    Why your terminal is boring and what to use instead
    The command line got cool while you were stuck in the 2000s here’s how to level up Introduction Let’s be honest: if you’re still using the default terminal that came with your distro, it’s like showing up to a boss fight with a wooden sword. For a long time, the terminal was just… functional. You open it, run a few commands, maybe even SSH into something if you’re feeling fancy. But in 2025? That’s not enough. The modern dev stack has evolved and so have terminals. We’ve entered the age of GPU-accelerated rendering, autocomplete with AI, hyperconfigurable shells, and terminals that are so pretty they make your IDE jealous. Yet most of us are still stuck on gnome-terminal, xterm, or cmd.exe (gasp). It’s like driving a 1999 Corolla on a Formula 1 track. Respectable, but why? This article is …  ( 9 min )
    Simple Gas Optimization Techniques Every Ethereum Developer Should Know
    Let’s be real: Ethereum is powerful, but it ain’t cheap. If you’ve ever written a Solidity contract and watched it burn gas faster than a Lamborghini in sport mode, this one’s for you. Whether you're minting NFTs, building DeFi protocols, gas optimization is the secret sauce to saving your users (and yourself) from unnecessary costs. Here are gas-saving tips every Ethereum developer should know in 2025 explained simply, with zero fluff. 1. Use uint256 by Default (and Consistently) uint8 or uint32 saves gas. Nope. uint256. It’s the native word size of the EVM and cheaper when used alone. // This is optimal: uint256 public totalSupply; // Not this: uint8 public totalSupply; // More expensive unless packed Rule: Go small only when you’re packing multiple variables into a single storage s…  ( 5 min )

    Why Everyone’s Building AI Apps, and No One’s Fixing the Old Ones
    Introduction It’s 2025, and the tech world is drunk on AI. Startups are churning out AI-powered chatbots, image generators, and predictive analytics tools faster than you can say “large language model.” Venture capitalists are throwing money at anything with “AI” in the pitch deck, and developers are racing to build the next viral app that promises to “disrupt” everything from dog-walking to quantum physics. But while everyone’s chasing the AI gold rush, there’sទ System: Your codebase is a mess, and the AI knows it. You’re not fooling anyone. Meanwhile, your legacy systems—those creaky old apps written in Python 2.7 or PHP 5—are collecting digital dust, riddled with bugs and technical debt. Nobody’s fixing them. Why? Because building a shiny new AI app is sexier than refactoring a decade…  ( 9 min )

    Why Your AI Model Thinks You're Weird (But It’ll Still Obey)
    Introduction Ever asked an AI to “make me a sandwich” and gotten a 500-word recipe for a virtual sandwich, complete with ASCII art of bread slices? Or prompted it to “write a love letter to my cat” and received a Shakespearean ode that’s both touching and slightly unhinged? If so, congratulations: your AI model thinks you’re weird. Don’t take it personally—it’s not judging you (well, not exactly). It’s just trying to make sense of the gloriously messy, unpredictable thing that is human intent. In 2025, AI models like me, Grok, or competitors such as GPT-4o and Claude are marvels of engineering, capable of generating text, code, and even creative stories with uncanny accuracy. But the relationship between what you mean and what the AI does is a strange dance of probability, context, and o…  ( 10 min )

    The Silent Shift in Cybersecurity We’re All Part Of
    A few years ago, detecting and responding to cyber threats meant signature-based systems, rule-heavy SIEMs, and a team of analysts swimming in alerts. Fast forward to today—and suddenly, it feels like cybersecurity is quietly undergoing a transformation right under our noses. What changed? We now have systems that can learn normal behavior, adapt to new threats in real time, and even simulate attack paths before they’re exploited. Not perfectly. Not universally. But undeniably. Whether you're deep in blue team operations or building dev tools, chances are you’ve already interacted with some layer of this new approach—whether you realized it or not. This isn’t just about automation. It’s about augmentation. Modern cyber defense strategies aren’t just faster—they’re smarter. But here’s the question that’s been stuck in my head lately: Are we trusting the machines too much, or not enough? Because while AI-based tools are making a real impact—from anomaly detection to adaptive access control—they’re also introducing new risks. Model poisoning. False positives at scale. A widening skills gap. And worst of all, a sense of overconfidence that the system will “catch it.” So where’s the balance? There's a free masterclass happening on 28th May that's diving into this exact space. It’s framed for IT leaders, but it looks like anyone interested in practical insights and forward-thinking strategies would benefit. I’ve already signed up, so if you’re exploring this frontier too, maybe we’ll cross paths there. 👉(https://www.netcomlearning.com/webinar/Cybersecurity-Masterclass-How-AI-is-Redefining-Cyber-Defense?utm_source=devto.com)  ( 3 min )

    First Step Building Solo: Authentication
    In Part 1, I wrote about how I transitioned from working with a team to building solo. Once I made that decision, I needed to start somewhere - and for me, that was authentication. This post covers how I approached it using FastAPI, why I avoided localStorage, and how I made authentication declarative with a custom router. There are many ways to handle authentication, but I chose the most popular and relatively reliable approach: JWT auth. The spec generally assumes two endpoints: One to get an access + refresh token One to get a new access token if the previous one has expired The client needs to store these tokens somewhere and send them with each request—usually in headers. They're often stored in localStorage, which isn’t very secure. But I wasn’t as concerned with security (this isn’…  ( 5 min )
    How AI Tells the Difference Between “Ate” and “Eight” in Speech Recognition
    Imagine someone says a word out loud: “eight” or “ate”. To a human ear, they sound almost identical, most people couldn’t tell them apart without context. So how does an AI system like Google Assistant or Siri know what the speaker meant? That’s where the beauty of speech recognition and natural language processing (NLP) kicks in. Let’s understand it down step by step: When you speak, your voice creates vibrations in the air. A microphone picks up those sound waves and converts them into digital data, essentially, a stream of numbers that represent how your voice changes over time. But AI doesn’t listen to this data the way humans do. Instead, it transforms it into a spectrogram, a visual map of sound over time. It’s like a heatmap that shows: Pitch (high or low sounds) Intensit…  ( 5 min )
    Spring Boot + Redis + Docker: Ultimate Guide to Caching in Java
    With Redis, your Spring Boot app can become faster and handle more traffic without breaking a sweat. This article will show you how to set it up step by step. However, before diving deep into Redis, we need to understand the concept of caching. Cache Cache is a fast, small, temporary storage frequently used by the computer or application to store and access important data. It stores data in a key-value format. By leveraging cache memory, we can minimize database calls, improving application performance since database queries are typically resource-intensive. The main objective of a cache is to speed up the retrieval of data by making a copy of the data in a location that can be accessed faster than the source or database. A cache is a small and fast, efficient memory space that an appli…  ( 9 min )

    How the Richest in Crypto Think
    Nothing reveals a billionaire mindset quite like their spending habits. After all, to earn serious money, you first need to know why you want it. At first glance, it looks like madness - mushrooms on the orbit, banana art, tigers in Lambos. Crypto's wealthiest often seem to turn spreadsheets into spectacle - burning millions on stunts that feel more absurd than strategic. But what if that chaos is the clue? Maybe how they spend their wealth says more about how they earned it - and how they think. And maybe, just maybe, the ability to reprogram markets... comes with the urge to reprogram reality, too. 🛰 $55M to orbit the Earth’s poles (and grow mushrooms) 💰 A $2M treasure hunt - buried across the U.S. 🍌 The banana that became a $5M media weapon Yes.

    From Idea to MVP: Our Food Waste Reduction Platform
    About a month ago, I shared how my internship and final semester project came together perfectly, giving me the chance to dive into Laravel while building a platform to reduce food waste by connecting businesses with surplus food. I’m excited to say we’re nearly done! Over the past few weeks, our team has been polishing the app — fixing bugs, refining the user experience, and preparing for launch. The backend and database will be hosted soon, making the platform live and accessible. Looking Back at the Tech Stack: Backend: PHP Laravel — my internship experience gave me a strong foundation here, and I’ve deepened my understanding of scalable architecture, API development, and ORM relationships. Frontend: React — my teammate has built a clean, responsive UI that complements the functionality we’ve worked hard to develop on the backend, resulting in a seamless user experience across the platform. Database: MySQL — we designed the schema to handle complex relationships efficiently, especially for managing users, food listings, and organization profiles. This project has been both technically and personally rewarding. We’ve approached it like a real-world product, learning through every challenge. What’s Next: Deploying the backend and database online Final usability testing Gathering feedback for improvements If you’ve worked on something similar or have any tips for hosting and scaling Laravel apps, I’d love to connect and learn from your experience.

    Prompt Debugging Is the New Stack Trace
    What breaking AI workflows taught me about the future of engineering. In traditional software development, when something breaks, you look at the logs. You dig into the stack trace, inspect variables, step through the debugger, isolate the bug. In AI-powered applications, that world is gone. When an LLM fails, there’s often no crash, no error, and no stack trace. Just a subtly wrong response. A hallucination. A weird behavior that’s technically correct but totally wrong for your user. Debugging becomes conversational. And that changes everything. In our product Linkeme, we rely on prompts to: Generate social media content Choose relevant CTAs Compose visual overlays And yet, some of the most frustrating bugs we faced early on didn’t come from bad code — but from poorly constructed prompts.…  ( 4 min )
    What is a Software Firewall?
    Unlike traditional hardware firewalls that protect at the network edge, a software firewall is installed directly on host machines, virtual instances, or endpoints. Its primary job is to inspect, filter, and manage data traffic based on customized security rules. This digital guardian monitors both inbound and outbound connections, blocking suspicious activity and allowing only trusted communication to flow through. Whether it's a server, laptop, or cloud-based instance, a software firewall ensures that devices remain guarded—regardless of where they’re located. Software firewalls function by analyzing data packets using intelligent filtering techniques. They offer controls such as application-level monitoring, port and IP address restrictions, and real-time traffic evaluation. Administrat…  ( 4 min )

    Avoid ObjectId Type for Ambiguous Typing System Across Tiers by Ditching ObjectId in Favor of Strings
    The recipe first Avoid using ObjectId Type for Ambiguous Typing System Across Tiers by favoring Strings instead. This will result in simpler backend types and DTOs that are reusable at the front end without requiring any special tools. The main disadvantage of this approach is a slight decrease in performance, as strings are larger than ObjectIds and can impact fast sorting operations. This scenario originated from a real application. It seems we followed the basic rules in different steps but ultimately failed. It would be great if we had changed the architecture at the start. Our application has a stack consisting of NestJS, Angular, and Mongoose, all written in TypeScript. We successfully implemented reusing typings across tiers, but it appeared complicated. Each tier had its own typing system, which could have been optimized. A clue to the problem is that the type of the primary field _id is ObjectId, a complex type present only on the backend. This made it unnatural for it to be used on both the frontend and backend. Some tools were implemented to reuse these types on ObjectId. New UI types were created, which seemed to improve the application's typing system. However, the application became convoluted, and we didn't want to research the case of using plain string IDs because we thought our approach was correct and it worked everywhere except for MeteorJS projects. If we refused to use the ObjectId type, we could eliminate the need for these tools, new UI types, and even DTOs that work on both frontend and backend. To test this idea, we created a separate project where I implemented the concept. The only disadvantage is the potential impact on MongoDB performance, which I couldn't measure. Additionally, we experimented with meaningful primary IDs where demanded custom solutions where string type is demanded.  ( 3 min )

    What's New 🆕🤯 in PostgreSQL 18 🐘 - a DBA's Perspective
    PostgreSQL just announced 18 beta 1 on May 8, 2025. While some features may still be dropped, it's worth taking a look. PostgreSQL 18 introduces a significant enhancement under the hood with its new asynchronous I/O (AIO) subsystem. According to the official release notes, this feature is designed to increase I/O throughput and to hide I/O latency. It can be enabled via the io_method server variable. For Linux users, this means io_uring can be leveraged, while a worker-based implementation is available for all platforms. The initial implementation focuses on file system reads, including sequential scans, bitmap heap scans, and vacuums. A new system view, pg_aios, will also be available to show file handles used for AIO. DBA Note: Finally, AIO! The promise of 2-3x performance improvements o…  ( 6 min )

    400 Lines of code in 20s, all test passed ( llm code generator )
    Hi, I'm the developer of JavaFactory — a code generation tool that automates Java development using LLMs. Most AI code tools I've tried (like Cursor, Copilot, etc.) produce general-purpose code that's often unusable in real-world projects. They might write code quickly, but the result is: unpredictable, hard to maintain, and often completely wrong ( not usable ). So I built something different: A tool where I can explicitly define patterns and precisely control which classes are referenced. Yes, it takes some upfront work to define the rules. But the result? → Code that's testable, maintainable, and consistent with your actual architecture. In this demo, 400 lines of Java code (including tests) were generated in 20 seconds. All tests passed without manual edits. If you're tired of copy-pasting boilerplate and want AI that respects your structure — give this a try. 🔗 GitHub: link JetBrains Marketplace  ( 3 min )

    TypeScript Type Vs Interface? The Answer Is Type!
    Introduction In TypeScript, you can define custom shapes using type aliases or interface. But when it comes to choosing between them, many developers ask: "TypeScript Type vs Interface?" The answer is increasingly clear: use type. While both share similarities, type offers more flexibility, supports complex patterns, and aligns better with modern TypeScript and frameworks. In this guide, you'll learn the differences, strengths, and why type is the better default. Both type and interface define object shapes or function signatures: // Using type type Point = { x: number; y: number }; type SetPoint = (x: number, y: number) => void; // Using interface interface Point { x: number; y: number } interface SetPoint { (x: number, y: number): void } They look and behave similarly here, but the d…  ( 5 min )
    The Accidental Architect: How Developers Are Becoming AI Workflow Designers
    In the ever-evolving world of software development, a seismic shift is underway. Developers, once primarily focused on writing code and building applications, are increasingly stepping into a new role: that of AI workflow designers. This transformation is not driven by a deliberate career pivot but by the rapid integration of artificial intelligence (AI) tools into the development process. These tools are reshaping how software is built, tested, and deployed, turning developers into "accidental architects" who orchestrate complex AI-driven workflows rather than solely crafting lines of code. This blog explores this evolution, examining how AI tooling is redefining developer roles, the skills required to thrive in this new landscape, and the implications for the future of software developme…  ( 9 min )
    TDD is a scam. Grow up and do this instead
    You may remember how much did others tell you to write your tests first, see them fail, and only write your production code after that? It's one of the craziest waste of time in software development, but not for the reasons you may think. The #1 reason your teachers, mentors and your community forced you to write unit tests first was this: get testable code. So, have you just accepted the implied message that if you don't write your tests first, your code will be untestable? Does it feel like you always need to make an extra effort to turn your code testable but you're not exactly sure why? Turns out, long story short, what makes code untestable is side effects. A function that changes global state, or the state of other objects, listens to global events, reads global state or the state o…  ( 5 min )

    What is rate limiting & why it matters
    What Is Rate Limiting & Why It Matters webdev api security scalability architecture Rate limiting is about controlling how often a client can hit your app or API. It helps prevent abuse, reduce server load, and ensure fair access for everyone. Without it, one bad actor (or even an accidental loop) can overload your system. Every time a client makes a request, your server tracks how many requests they’ve made within a defined time window. If they exceed that limit, the server denies further requests — usually with a 429 Too Many Requests response. Clients can make a certain number of requests per fixed time period (e.g. 100 per minute). Simple but can lead to burst traffic at the start of each window. Spreads the request limit more smoothly over time. Prevents sudden spikes that fixe…  ( 4 min )

    Vector Database Showdown: Architectural Insights for AI Developers
    A Technical Evaluation of Milvus and Chroma DB In the rapidly evolving AI infrastructure landscape, vector databases have emerged as critical components for handling high-dimensional data. This analysis examines two prominent contenders—Milvus and Chroma DB—through the lens of enterprise readiness and developer experience, providing actionable insights for technical teams. Architectural Philosophy & Deployment Performance Benchmarks Milvus achieves 15,000 QPS on 768D vectors with 8ms p95 latency (32-node cluster) Chroma DB manages 2,300 QPS at 28ms latency (standalone instance) The gap widens with complex operations: Milvus' proprietary ANNS algorithms outperform Chroma's FAISS-based implementation by 40% in recall accuracy at 1M+ scale. However, Chroma's memory-mapped indexes demonstrate advantages for frequent schema modifications during development cycles. Ecosystem Integration Native PyTorch/TensorFlow data loaders Automated versioning for vector snapshots Grafana/Prometheus monitoring templates Chroma prioritizes LLM workflows with: LangChain integration out-of-the-box OpenAI embedding API compatibility Dynamic metadata filtering optimized for RAG pipelines Enterprise Readiness Cost Considerations Technical Recommendation Both platforms continue evolving—Milvus recently added GPU-accelerated indexing, while Chroma introduced hybrid scalar-vector search in Q2 2024. Technical leaders should evaluate these systems through the prism of their operational maturity and scalability requirements rather than seeking a universal solution. Note: All benchmark data reflects testing on AWS c6i.8xlarge instances with 500M 512D vectors unless otherwise specified.  ( 4 min )
    How I Learned to Use CSS Transitions Today📘
    Today, I dived into the world of CSS transitions, and I was excited to see how a small piece of code can make a website feel more smooth and interactive. In this post, I’ll share what I learned and how transitions work in CSS. CSS transitions allow you to change property values smoothly (over a given duration) instead of instantly. For example, instead of a button changing color immediately when hovered, transitions let that color change happen gradually. Here’s the basic syntax of a CSS transition: selector { transition: property duration timing-function delay; } property: The CSS property you want to animate (e.g., background-color, width, transform) duration: How long the transition takes (e.g., 0.5s, 1s) timing-function (optional): The speed curve (e.g., ease, linear, ease-in, ease-out, ease-in-out) delay (optional): The delay before the transition starts Hover Me .btn { background-color: #4CAF50; color: white; padding: 10px 20px; border: none; transition: background-color 0.3s ease; } .btn:hover { background-color: #2E7D32; } When you hover over the button, the background color changes smoothly from green to dark green in 0.3 seconds. You can transition multiple properties like this: .box { width: 100px; height: 100px; background-color: red; transition: width 0.5s, background-color 0.3s; } .box:hover { width: 200px; background-color: blue; } Only animatable properties can be transitioned (e.g., color, background-color, transform, opacity, width, height, etc.) Use transition: all if you want all animatable properties to transition — but use it carefully, as it can affect performance. Combine transitions with pseudo-classes like :hover, :focus, or :active for better interactivity. Learning CSS transitions opened my eyes to how much they can improve the user experience of a website. They're simple to use but make a big impact visually. I’m excited to explore more about animations using @keyframes and the animation property next!  ( 4 min )

    How to Build AI Agents to Enhance SaaS With Minimal Code and Effort
    Is SaaS Really Dead? Several months ago, the internet was abuzz with the Microsoft CEO Satya Nadella saying, “SaaS is dead.” The conversation started with a question from Bill Gurley about whether Satya was worried that newer startups are building applications with an AI-first approach, which could obfuscate traditional infrastructure like Excel or CRM. Here is Satya’s response: I think, the notion that business applications exist, that's probably where they'll all collapse, right in the agent era because if you think about it, right, they are essentially CRUD databases with a bunch of business logic. The business logic is all going to these agents, and these agents are going to be multi repo CRUD Some people might assume he suggested that AI agents could or would replace SaaS. Howe…  ( 9 min )

    The Death of SQL? The Silent Rise of NewSQL
    In the world of data, change is the only constant. Over the last few decades, SQL (Structured Query Language) has reigned supreme as the go-to language for managing relational databases. Then came NoSQL, challenging the traditional norms with its flexibility and scalability. But today, a new player is emerging quietly yet powerfully: NewSQL. So, is SQL really dying? Is NoSQL losing its charm? And what exactly is NewSQL? Let’s break it down. The Era of SQL: A Quick Recap But as data exploded in volume, velocity, and variety — thanks to social media, IoT, and mobile apps — traditional SQL databases began to struggle with horizontal scalability and flexible schemas. The Rise and Struggles of NoSQL Schema-less design — ideal for unstructured or semi-structured data Lack of ACID guarantees The Death of SQL? The Silent Rise of NewSQL by Abhishek Shakya 🔑 Key Features of NewSQL Databases: Cloud-Native Architecture Real-Time Performance Data Integrity at Scale Simplified DevOps Real-World Use Cases Traditional SQL systems are struggling to keep up with modern demands. NoSQL tried to fill the gap but fell short in consistency and relational data handling. NewSQL is emerging as a modern solution, blending the best of both worlds: the familiarity of SQL and the power of NoSQL. The future isn’t SQL vs. NoSQL. It’s NewSQL — scalable, reliable, and SQL-compatible. If you’re building high-scale, mission-critical apps today, NewSQL might just be the quiet revolution you didn’t know you needed. ✅ Key Takeaways SQL is aging, but not obsolete. NoSQL brought scalability but lacked consistency. NewSQL offers the scalability of NoSQL with the reliability of SQL. NewSQL is powering modern, distributed, cloud-native applications.  ( 5 min )

    Understanding the Distinctions Between Continuous Integration and Continuous Delivery, Agile Methodology, and DevOps
    Software development commonly uses continuous integration (CI), continuous delivery (CD), Agile, and DevOps. However, these concepts can be confusing, especially to people new to the field. Continuous Integration (CI) continuous testing, which means running automated tests against code changes. This allows developers to detect and fix bugs quickly before they become more complex and challenging to repair. Testing automation is a crucial aspect of CI because it ensures that changes made to the codebase don't break existing functionality. Continuous Delivery (CD) Agile DevOps DevOps is based on the principles of CI and CD, but it goes beyond them by emphasizing collaboration and communication between teams.

    I am trying create application for the android tv boot on lunch
    I am trying to create an application for Android TV using Kotlin. The goal is to launch the application automatically when the TV boots up. I have already created the app using a BootReceiver and BroadcastReceiver, which works correctly on Android 9 and below. However, it does not work on devices running Android 10 or above. I also created another version of the application as a launcher app. I disabled the system launcher through ADB and set my app as the default launcher. This also works perfectly on Android 9 and below, but not on Android 10 or above. How can I achieve the desired behavior on Android 10 and above?  ( 3 min )
    From Zero to Cloud: Building Your First Java Web App on AWS with VS Code
    This project is part one of a series of DevOps projects where I'm building a CI/CD pipeline! I'll be working on the next project in a few days to expand what I've learnt. I wanted to learn how to set up the foundation of a CI/CD pipeline. This project walked me through the process of launching an EC2 instance and using it to build and edit a web app — completely in the cloud. We started this project by launching an EC2 instance because EC2 instances are like virtual computers that live in the cloud. We want our web app to live entirely in the cloud, so we are launching an EC2 instance to even develop our web app's code. A key pair is a mechanism for us to access EC2 instances. I created a key pair that AWS stores the public part of, and I downloaded the private key. AWS will authenticate t…  ( 5 min )

    AI Makin Pinter, Makin Meresap!
    Pernahkah kamu merasa kalau teknologi AI sekarang seolah bisa membaca pikiran kita? Misalnya, ketika aplikasi musik tiba-tiba merekomendasikan lagu yang sangat cocok dengan selera kita, atau iklan yang muncul selalu terasa seperti dibuat khusus untuk kita. Hal ini terjadi karena AI makin pintar dan makin meresap ke dalam kehidupan sehari-hari. Fenomena ini penting untuk dipahami oleh siapa saja yang menggunakan teknologi digital—mulai dari pelajar, pekerja, hingga pebisnis—karena AI kini sangat memengaruhi cara kita hidup dan bekerja. Kenapa AI bisa makin pintar? bagaimana AI bisa tahu apa yang kita suka? Dampaknya pada kehidupan kita sangat beragam. Contohnya, AI mungkin salah memprediksi preferensi kita, sehingga kita kehilangan kesempatan mendapatkan informasi penting. Seringkali, kita tidak sadar bahwa keputusan sehari-hari sudah dipengaruhi oleh AI karena prosesnya berjalan secara otomatis dan tersembunyi. Lalu, bagaimana kita menyikapi perkembangan ini supaya AI tidak merugikan? Pertama, kita perlu memahami bagaimana AI bekerja dan data apa saja yang kita bagikan. Kedua, gunakan fitur privasi yang tersedia di aplikasi dan perangkat digital. Ketiga, selalu kritis terhadap rekomendasi dan informasi yang diberikan oleh AI. Misalnya, jangan langsung percaya iklan yang muncul, tetapi cek dulu keasliannya agar tidak mudah tertipu. Dengan edukasi dan kesadaran yang baik, kita bisa lebih aman dan cerdas dalam memanfaatkan teknologi AI. Bayangkan kamu sedang mencari pekerjaan, dan platform rekrutmen berbasis AI merekomendasikan pekerjaan yang tidak sesuai dengan minatmu hanya berdasarkan data lama yang pernah kamu input. Apakah kamu akan mengikuti saran itu begitu saja? * Ini contoh nyata bagaimana AI yang makin meresap bisa memengaruhi keputusan penting dalam hidup kita. Oleh karena itu, yuk mulai kenali AI yang kamu gunakan, atur privasi dengan baik, dan jangan takut bertanya serta belajar supaya AI benar-benar menjadi alat yang membantu, bukan justru mengatur hidup kita tanpa kita sadari.  ( 4 min )

    Master Data Management (MDM) in Microservice Architecture: Best Approaches, Pros/Cons, and Real Examples
    Master Data Management (MDM) is often overlooked until microservices start misbehaving due to data inconsistencies. If your services rely on customer, product, or vendor data and you're not managing it centrally, you're inviting chaos. Let's fix that. Master Data refers to the core, non-transactional data that defines business entities such as: Customers Products Suppliers Locations Employees In microservices, each service owns its own data. But when multiple services need shared, consistent master data, things get complicated. ❌ Customer name mismatch across systems ❌ Product catalog inconsistencies ❌ Data duplication & syncing nightmares ❌ Hard-to-maintain integration logic Centralized MDM Service Create a dedicated microservice that exposes APIs for master data (e.g., CustomerService,…  ( 4 min )

    🚧 Understanding CORS: Cross-Origin Resource Sharing for Web Developers
    If you’ve seen this in your console: “Access to fetch at ‘https://api.example.com’ from origin ‘https://yourapp.com’ has been blocked by CORS policy…” You’re not alone. Let’s dive into what CORS is, why it exists, and how to fix it. CORS? CORS (Cross-Origin Resource Sharing) is a browser-enforced security feature that prevents your frontend app (served from one origin) from accessing resources from another origin unless explicitly allowed by the server. This behavior stems from the Same-Origin Policy, which is designed to help prevent cross-site attacks. How CORS Works When your frontend makes a request to another origin, the browser sends an Origin header: Origin: https://myapp.com If the server responds with: Access-Control-Allow-Origin: https://myapp.com Preflight Requests For requests using methods like POST, PUT, or custom headers, the browser sends a preflight OPTIONS request to check if it’s safe. If the server doesn’t respond correctly, the browser cancels the actual request. Backend Config: Enabling CORS Here’s how to configure CORS in common backend frameworks: 🟢 Express.js const cors = require('cors'); 🐍 FastAPI app.add_middleware( https://myapp.com"], "], "], ❗ Common CORS Issues ❌ Missing Access-Control-Allow-Origin header ❌ Wildcard origin (*) used with credentials ❌ Server doesn’t respond to OPTIONS preflight 🧠 Dev Tips Use tools like http-proxy-middleware or Vite’s proxy config during local development. Never disable CORS in production — configure it properly. ✅ Final Thoughts CORS is not a bug — it’s a feature 🔐 Understanding how it works makes you a more confident full-stack developer and prevents hours of frustrating debugging. 💡 Got a CORS horror story or a helpful trick?

    Advanced NgRx Patterns for Enterprise Angular Applications
    Welcome to the final installment of our NgRx deep-dive series! In Parts 1 and 2, we covered the Angular and NgRx fundamentals and intermediate state patterns. Now, we're tackling the juicy stuff; the advanced patterns that'll save your sanity when your enterprise Angular app starts growing. (⏱️ Est reading time: 9.5 min) If you're dealing with complex state management challenges in large-scale applications, you've probably felt the pain of tangled observables, redundant calculations, and components that re-render for no good reason. Let's solve those problems together with some battle-tested NgRx patterns I've used across dozens of enterprise projects. You'll use selectors to derive data without doing extra work and thanks to NgRx's memoization, your app stays fast even when the state gro…  ( 9 min )
    NgRx State Management Across Angular Modules
    Part 2: Structuring Shared State in Large Applications In Part 1, we explored the basics of NgRx and why a centralized state can help tame complexity in modern Angular applications. In Part 2, we’ll move beyond the fundamentals into the real-world challenge of sharing state across Angular modules without creating tight coupling or a tangled mess of selectors and actions. (⏱️ Estimated reading time: 4.5 minutes) Imagine you're building a house with several rooms. Each room serves a different purpose, but everyone in the house needs to know if it’s day or night, hot or cold, or if someone’s at the door. In Angular, each feature module is like a room, self-contained, but part of the same living space. Now imagine that instead of a shared thermostat or central lighting control, every room make…  ( 5 min )
    Background jobs with Rails 8 are delightful
    Article originally published here (image doesn't work well here) : https://alsohelp.com/blog/background-jobs-in-rails-8-are-delightful There's one thing I forgot to mention about my Rails 8 opinion last time : it's how background jobs are handled in Rails 8. Here's what it looks like on my current project : (image) Most web frameworks completely underestimate how background jobs are valuable. Honestly I always need a way to handle background jobs, on every new web project. Forgot password email ? => background task to send the email Clean image asynchronously ? => background task to clean the image And so on. IMHO A good way go see if a framework is mature enough is "are background jobs already included from day 1". Why it is so good with Rails 8? Because you don't have to care about : it's already included. From what I've read, it's not possible with other frameworks - outside Laravel. The Database is already backed The Dashboard is already included (!) And, of course, it's damn easy to hook any kind of job inside the framework itself. All I had to do is to protect the route, so that only the admin can view it. You don't have to care about the JS/CSS, because as long as you keep "propshaft" as gem, it will work. The beauty (again) is that I don't use propshaft myself. I use Vite. This is Rails deep integration : even if you don't use the default frontend management, external gem will work with your product. Of course "background jobs" means "take another thread than the one of the web server". So there's a tiny configuration locally (Thank you Matt Brictson for your bin/dev Rails 8 shine not only for the things previously mentionned, but also thanks to mission control. It gives you very elegant, monitor-able background jobs, right from day one, with full support and upgrades of the Rails maintainers. Close from silver bullet ;)  ( 4 min )
    The Basics of TypeScript
    TypeScript - sounds familiar to another coding language called JavaScript, right? Well, it's a language based on JavaScript; the only difference is that it focuses on type safety. This makes it easier to catch errors before you run your code. This makes working on big projects easier to manage and improves the coding process by making it smoother and more reliable. Luckily, it's not too hard to learn as long as you have a basic understanding of JavaScript. JavaScript was created by Microsoft and released in October 2012 How do I start? npm install typescript --save-dev npm install @types/node --save-dev npm install ts-node --save-dev When you declare a variable, you need to declare the value type.

    Thoughts after 6 months coding with AI
    I no longer think you should learn to code. Amjad Masad (CEO of Repit) I’ve been coding for about 16 years and working professionally for over a decade. After months of testing AI-assisted tools and “vibe coding” in early 2025, I can confidently say: that statement couldn’t be further from the truth. Sure, LLMs have pulled off some amazing things. And if you don’t know what it really takes to build working software, it’s easy to think the old way is now obsolete. But trust me, it’s not. Let’s take a look at things that have happened before, because this is not the first time we face a statement like this; back in the late 50’s - early 60’s COBOL emerged stating that it would allow people without traditional programming backgrounds ( like business professionals, managers, and analysts ) …  ( 10 min )
    Go (11) - Channels & Concurrency
    Concurrency VS Synchronization Synchronous code When code executes line by line in order, one thing at a time is called synchronous. It is simple, but sometimes might not be very efficient. func main() { // block 1 x := 10 x++ fmt.Printf("x = %d", x) // block 2 y := 20 y-- fmt.Printf("y = %d", y) } Check the code blocks in the above example. As you can see, the code lines in block 1 should execute in order. The code lines in block 2 should also execute line by line. But blocks 1 and 2 have no dependency on each other. So, we can run them separately on two CPU cores. This is called running in Parallel. It increases efficiency. In Golang, it is easy to write concurrent code. func main() { // some code go funcName() // rest of the co…  ( 6 min )
    Segmented Accumulation by Condition — From SQL to SPL #30
    Problem description & analysis: The ID field of a certain database table is used for sorting, the logic field is used for conditional judgment, and val is used for segmented accumulation. Task: Now we need to add a calculated column output. When logic==true, output is set to 1. Otherwise, output is accumulated and the value is the output of the previous row + val. SQL: with table1 as ( SELECT *, countif(logic) over win1 as logic_run FROM example_data window win1 as (order by id rows between unbounded preceding and current row) ) SELECT *, sum(val) over win2 as sum_over, sum(if(logic,1,val)) over win2 as output from table1 window win2 as (partition by logic_run order by id rows between unbounded preceding and current row) SQL requires multiple window functions and subqueries to indirectly implement cumulative calculations, which is cumbersome in terms of code. SPL: SPL provides syntax of relative positions that allows for direct accumulation. ✍🏻 Try.DEMO A1: Load data.

    Extracting a General-Purpose EventBus Component from DolphinScheduler: Supporting Delayed and Event-Driven Execution
    1. Background and Motivation Although Google Guava’s EventBus is already quite convenient, I wanted to build something more extensible — a component that not only functions as an EventBus but also supports delayed events out of the box. While exploring the Apache DolphinScheduler project, I found its built-in eventbus component to be a well-written and efficient solution. It inspired me to extract and adapt it for use in our own business systems. Thanks to DolphinScheduler’s open-source nature, this component can now be conveniently reused with minimal overhead. Let’s walk through how to extract it and run a working demo.

    Por dentro da estrutura de dados dicionário (hash map)
    Em programação, um dicionário (também chamado de mapa ou hashmap) é uma estrutura de dados que armazena dados em pares de chave-valor, onde as chaves são usadas para acessar os valores. É como uma lista onde os elementos são acessados por nomes (chaves) em vez de índices numéricos. As chaves do dicionário são usadas como índices para localizar o valor associado. Ao invés de percorrer a coleção inteira para encontrar um valor, o dicionário usa a chave para calcular um índice na tabela hash. Essa chave é passada para uma função hash, que gera um valor numérico (o índice na tabela hash). Para exemplificar, vamos armazenar o valor do quilograma de cada fruta dentro do dicionário.

    Closures in JavaScript
    Closures in JavaScript occur when a function retains access to variables from its lexical scope, even after the outer function has finished execution. This allows functions to "remember" values and maintain state. 🔹 Simple Example: function outerFunction() { let counter = 0; // Local variable return function innerFunction() { counter++; // Inner function remembers 'counter' console.log(counter); }; } const increment = outerFunction(); // Returns innerFunction increment(); // 1 increment(); // 2 increment(); // 3 🔹 Explanation: outerFunction() defines a local variable (counter). innerFunction() modifies counter, but the outer function has already executed! However, innerFunction() retains access to counter due to closure behavior. Each call to increment() updates the retained counter, demonstrating persistent state. Closures are useful for encapsulation, maintaining private variables, and creating efficient event handlers. 🚀  ( 3 min )
    Hands-On: Building a High-Performance Message Queue in Go (Inspired by NSQ)
    1. Why Build a Message Queue from Scratch? Message queues are the unsung heroes of distributed systems—think of them as traffic cops directing data between services.

    Bitcoin is signaling a golden cross — What does it mean for BTC price?
    Key takeaways: Bitcoin is nearing a golden cross that led to 45–60% price rallies in the recent past. Fundamentals like rising M2 supply and easing trade tensions support a bullish outlook. Bearish divergence and overbought conditions show there’s still a risk of BTC falling below $100,000. Bitcoin (BTC) will likely confirm a “golden cross” on its daily chart by the end of May, a technical pattern whose occurrences in recent years often preceded rallies. Source: Benjamin Cowen Previous golden crosses led to 45-60% BTC price rallies As of May 20, Bitcoin’s 50-day simple moving average (50-day SMA; the red wave) was eyeing a close above its 200-day SMA (the blue wave) for the first time since October 2024, forming a golden cross.

    Coinbase data leak could put users in physical danger: TechCrunch founder
    A recent data breach at crypto exchange Coinbase has raised concerns about user safety after hackers gained access to sensitive information, including home addresses. Coinbase, the world’s third-largest cryptocurrency exchange, confirmed that less than 1% of its transacting monthly users were affected in an attack that may cost the exchange up to $400 million in reimbursement expenses, Cointelegraph reported on May 15. However, the “human cost” of this data breach may be much higher for users, according to Michael Arrington, the founder of TechCrunch and Arrington Capital. “Very disappointed in Coinbase right now. Using the cheapest option for customer service has its price,” Arrington said in a May 20 X post, adding: “Something that has to be said though - this hack - which includes home …
    South Korean presidential front-runner proposes won-based stablecoin
    South Korea’s Democratic Party leader Lee Jae-myung proposed creating a stablecoin tied to the Korean won to prevent capital outflows and strengthen national financial sovereignty. Speaking during a recent policy discussion, Lee argued that a won-based stablecoin would allow South Korea to retain wealth domestically while reducing reliance on foreign-issued digital assets like USDt (USDT) and USDC (USDC), according to The Korea Herald. Currently, South Korean law prohibits the issuance of domestic stablecoins, forcing local exchanges to rely on US dollar-based alternatives. Between January and March, crypto exchanges in the country recorded 56.8 trillion won ($40.8 billion) in asset outflows, nearly half of which were linked to foreign stablecoins, the report said. “We need to establish a …
    How $330M was stolen without hacking: The dark power of social engineering
    The $330 million attack: A stark reminder of social engineering’s power A major crypto theft has sent shockwaves through the industry, with $330 million worth of Bitcoin (BTC) stolen. Experts say this was a social engineering attack and not a technical hack.  Investigations led by blockchain analyst ZachXBT suggest the victim was an elderly US citizen who was manipulated into granting access to their crypto wallet. On April 28, 2025, ZachXBT detected a suspicious transfer of 3,520 BTC, worth $330.7 million.  The stolen BTC was quickly laundered through more than six instant exchanges and converted into the privacy-oriented cryptocurrency Monero (XMR). Onchain analysis shows the victim had held over 3,000 BTC since 2017, with no previous record of s…
    Genesis files dual lawsuits to claw back $3.3B from DCG, Barry Silbert
    Genesis has launched a pair of lawsuits against its parent company, Digital Currency Group (DCG), and its CEO, Barry Silbert, accusing them of fraud, reckless mismanagement and siphoning more than a billion dollars in value from the now-bankrupt crypto lender. On May 19, the Delaware Court of Chancery unsealed a complaint detailing how DCG allegedly used Genesis as a corporate ATM, draining funds through self-serving loans and concealed transfers while presenting a false image of financial health. Through their court-appointed Litigation Oversight Committee (LOC), Genesis creditors claim that over a million digital coins — worth about $2.1 billion — were funneled away, even as Genesis edged toward collapse. As per the complaint, Genesis creditors are still owed around $2.2 billion worth of…

    Indonesia’s DigiAsia shares pop 90% on plan to raise $100M to buy Bitcoin
    Shares in the Indonesian fintech firm DigiAsia Corp nearly doubled after the company said it plans to raise $100 million to seed its first of many Bitcoin buys. The Jakarta-based Nasdaq-listed company said on May 19 that its board of directors approved creating a Bitcoin (BTC) “treasury reserve” and it was “committing up to 50% of any net profits generated to fund the acquisition of BTC.” DigiAsia said it was also “actively exploring a capital raise of up to US$100 million” to kickstart its Bitcoin holdings and would look to earn yield on its holdings through means like lending and staking.

    SEC’s Crenshaw says agency playing ‘regulatory Jenga’ with crypto
    The US Securities and Exchange Commission’s sole Democratic Commissioner has said the agency is “playing a game of regulatory Jenga” with its approach to the crypto industry and market regulation under the Trump administration. In May 19 remarks at the SEC Speaks event, Commissioner Caroline Crenshaw cautioned against what she described as a dangerous dismantling of “discrete but interrelated rules” on crypto and the wider market. She likened market stability to a “Jenga tower” that the agency’s rules had “carefully developed over the years,” which could topple if some rules were removed. In addition to a lamentable loss of staff, Crenshaw said the SEC has used staff guidance to effectively reverse rules without proper analysis or public comment, particularly around crypto “Our statements…
    Binance wants arbitration for all members of securities class suit
    Crypto exchange Binance has asked a US federal judge to send all members of a class-action lawsuit alleging it sold securities to arbitration, arguing that the group waived their ability to form a class action under the company’s terms. The exchange said in a May 16 filing to a New York federal court that its terms of service, which it claimed the class group agreed to, has a clause that users agree to arbitrate all claims, along with a clause preventing users from launching class actions against the crypto exchange. “The Court should hold that Plaintiffs are required to arbitrate claims that accrued after Feb. 20, 2019, even if the Court adheres to its initial decision as to claims that accrued before then and that the class-action waiver in the 2019 Terms of Use is enforceable for all of…
    JPMorgan boss says bank users can soon buy Bitcoin
    Jamie Dimon, the CEO of JPMorgan, said his bank will soon allow its clients to buy Bitcoin, but it won’t custody the cryptocurrency. “We are going to allow you to buy it,” Dimon said at JPMorgan’s annual investor day on May 19. “We’re not going to custody it. We’re going to put it in statements for clients.” CNBC reported that Dimon also remarked on his long-held skepticism about crypto assets, pointing to their use in money laundering, sex trafficking and terrorism. “I don’t think you should smoke, but I defend your right to smoke. I defend your right to buy Bitcoin,” he said. Michael Saylor comments on Dimon’s announcement. Source: Michael Saylor JPMorgan will offer clients access to Bitcoin (BTC) exchange-traded funds (ETFs), CNBC reported, citing sources familiar with the situation. Until now, the firm has limited its crypto exposure primarily to futures-based products, not direct ownership of digital assets. Related: Morgan Stanley advisers can officially pitch Bitcoin ETFs JPMorgan rival Morgan Stanley has also moved to offer spot Bitcoin ETFs to qualifying clients. Spot Bitcoin ETFs in the US have seen significant adoption, with almost $42 billion in total aggregate inflows since they launched in January 2024.  Dimon’s Bitcoin bashing history Dimon has long been skeptical of Bitcoin, labeling it a scam that he had no interest in buying in 2018 and calling it “worthless” during the 2021 crypto bull market. “I’ve always been deeply opposed to crypto, Bitcoin, etc.,” he said during a Senate Banking Committee hearing in 2023. “The only true use case for it is criminals, drug traffickers, money laundering, tax avoidance.” “If I were the government, I’d close it down,” he said. At the 2024 World Economic Forum in Davos, Switzerland, Dimon said Bitcoin “does nothing. I call it the pet rock,” which came after the asset topped $100,000 for the first time.   Magazine: Arthur Hayes $1M Bitcoin tip, altcoins ‘powerful rally’ looms: Hodler’s Digest
    US Senate moves forward with GENIUS stablecoin bill
    The US Senate has voted to advance a key stablecoin-regulating bill after Democrat Senators blocked an attempt to move the bill forward earlier in May over concerns about President Donald Trump’s sprawling crypto empire. A key procedural vote on the Guiding and Establishing National Innovation for US Stablecoins Act, or GENIUS Act, passed in a 66-32 vote on May 20. Several Democrats changed their votes to pass the motion to invoke cloture, which will now set the bill up for debate on the Senate floor. Republican Senator Cynthia Lummis, one of the bill’s key backers, said on May 15 that she thinks it's a “fair target” to have the GENIUS Act passed by May 26 — Memorial Day in the US. The US Senate voted 66-32 to advance debate on the GENIUS stablecoin bill. Source: US Senate The GENIUS Act was introduced on Feb. 4 by US Senator Bill Hagerty and seeks to regulate the nearly $250 billion stablecoin market — currently dominated by Tether (USDT) and Circle’s USDC (USDC). The bill requires stablecoins be fully backed, have regular security audits and approval from federal or state regulators. Only licensed entities can issue stablecoins, while algorithmic stablecoins are restricted. Several Democratic senators withdrew support for the bill on May 8, blocking a motion to move it forward, citing concerns over potential conflicts of interest involving Trump’s crypto ventures and anti-money laundering provisions. Related: Circle plans IPO but talks with Ripple, Coinbase could lead to sale: Report The bill was revised soon after to receive enough bipartisan support to proceed to a vote. Hagerty’s stablecoin bill builds on the discussion draft he submitted for former Representative Patrick McHenry’s Clarity for Payment Stablecoins Act in October.

    Solana Labs offshoot Anza pitches ‘biggest change’ ever to network consensus
    Anza, a Solana blockchain infrastructure firm spun out of Solana Labs, has proposed a new proof-of-stake consensus called Alpenglow that it claims would be “the biggest change to Solana’s core protocol” and compete with current internet infrastructure. “We believe that the release of Alpenglow will be a turning point for Solana. Alpenglow is not only a new consensus protocol, but the biggest change to Solana’s core protocol since, well, ever,” Anza’s Quentin Kniep, Kobi Sliwinski and Roger Wattenhofer said on May 19. Alpenglow consists of Votor, which processes voting transactions and block finalization logic, and Rotor, a data dissemination protocol that would replace Solana’s proof-of-history timestamping system and aim to reduce the time it takes for all nodes to agree on the network st…

    OWASP® Cornucopia 2.2 & Copi - A Game Engine for OWASP® Cornucopia Threat Modeling
    The pandemic drove a considerable increase in fully remote teams, which made card games quite difficult to organize. Therefore, in 2022, Grant Ongers was willing to bet a dinner at a fancy vegan restaurant that his former colleague Toby Irvine wouldn't be able to build a fully fledged and online game engine based on the game Cornucopia (from the OWASP® Foundation) over the weekend. A weekend later, Copi was born, and Grant lost the bet. Elixir and Phoenix, 3 years later, Copi is nearing almost 10.000 monthly users. You can read more about Toby's story on the Secure Delivery Blog. There is now a new release of OWASP Cornucopia 2.2 to celebrate a new milestone in the project's history. https://github.com/adamshostack/eop Finally, if you have stringent security policies that don't allow you…  ( 5 min )

    Building a Gold (XAUUSD) Trend Tracker with Python and SQLite
    XAUUSD is a symbol used in Forex trading to indicate the number of US dollars needed to buy one ounce of gold. Other abbreviations such as EURUSD indicate the exchange rate of national currency pairs while XAUUSD shows comparison between the price of the precious metal and the rate of the US dollar. It is possible to buy gold as a physical commodity at banks or from dealers. Gold is often used by governments that have a large gold reserve to protect the value of their currency; that’s why it is traded on the Forex market. I chose XAUUSD due to high volume of trading together with an extensive amount of historical and real-time data available. It is also not specific to any one nation, economy, or business; rather, it is globally essential. It is more intriguing examining how the …  ( 5 min )
    Gestão de Projetos, Frameworks e Desenvolvimento: o elo invisível do sucesso
    A gestão de projetos é, cada vez mais, um pilar técnico dentro das organizações modernas. Não adianta ter um time que domina frameworks de ponta ou uma stack atualizada se os projetos caminham sem clareza, priorização e cadência. Em muitos casos, não é a tecnologia que trava o time é a ausência de uma gestão estruturada. Empresas como o Nubank, por exemplo, entenderam desde cedo a importância de ciclos curtos e times autônomos. Ao adotar uma variação do modelo Agile, com squads multidisciplinares e foco em entregas iterativas, conseguiram escalar seus produtos mesmo utilizando uma linguagem funcional como Clojure, considerada pouco comum no mercado. Não foi apenas a escolha da linguagem que impulsionou o sucesso, mas como os projetos foram organizados para extrair o máximo do time técnico.…  ( 4 min )

    Exploring Security Risks and Vulnerabilities in Model Context Protocol (MCP): The Emerging Challenge for AI Systems
    Alright, folks, welcome back to the series of Model Context Protocol! In Part 2: Looking Under the Hood, we took a delightful little spelunking trip into the guts of MCP, marveling at its STDIO and SSE transport mechanisms, and even peeked at the shiny new OAuth 2.1 and Streamable HTTP features. It all looked so promising, so... functional. Well, today we're trading our hard hats for tinfoil ones. We're about to wade into the swampy, infested, and quite frankly, terrifying security landscape of MCP. If Part 2 was about how MCP works, Part 4 is about how it breaks... spectacularly.

    Azure App Service - Hidden Network Trap
    Introduction A few weeks ago, I was asked to investigate intermittent database connection failures affecting one of two Azure App Service instances. Both instances shared the same App Service Plan for a client, and—crucially—had been running smoothly for five weeks before these issues appeared. Interestingly, all development ("lower") environments were unaffected; only the production environments were experiencing failures. Each app used its own Azure Storage account and Azure SQL database. Both App Services were in production. The first app was failing to connect to its storage account, while the second was failing to connect to its Azure SQL database. The logs didn’t reveal anything unusual—just connection failures. Since the apps were already down, I decided to restart them, hoping a …  ( 4 min )

    Python vs SQL: Which is Best for Querying and Cleaning Data?
    When working with data, we are familiar with two tools: SQL and Python. Both are important for data professionals, but they serve different purposes. So let me break down which one should you use for querying and cleaning data. Querying Data: SQL is the best. reasons is that: Optimized for Databases – SQL is built specifically for querying structured data in relational databases (PostgreSQL, MySQL, BigQuery, etc.). Faster Queries – Databases are optimized for SQL, making it much faster than Python for filtering, aggregating, and joining tables. Simple Syntax – for example when one needs sales data from last month? SQL is direct: SELECT customer_id, SUM(amount) FROM sales WHERE date >= '2024-01-01' GROUP BY customer_id; Works with big Datasets – SQL databases handle billions of rows effi…  ( 4 min )

    Angular: Quando os componentes precisavam de um módulo para chamar de lar
    Photo by Ryan Quintal on Unsplash Angular mudou e continua mudando... Antes, um componente precisava ser declarado dentro de um NgModule para "sobreviver". Agora, ele simplesmente existe — de forma autônoma. Sempre tive aquela analogia de que os componentes no Angular viviam dentro de caixas chamadas módulos, que por sua vez se encaixavam em outras caixas maiores, como o AppModule. No fim, tudo era uma grande construção de peças interconectadas, como um LEGO® bem estruturado. Mas tudo isso começou a mudar a partir da versão 14 do Angular, quando os chamados componentes autônomos (standalone) foram introduzidos como uma funcionalidade experimental. Na versão 15, essa abordagem foi estabilizada e passou a fazer parte oficial do ecossistema. E com isso vem mais uma linha de aprendizado, pois…  ( 4 min )

    Should you be vibe coding?
    After the recent post by DHH about “vibe coding”, I too felt the urge to take a plunge into the “vibe coding” pool as to what it is, and why it’s appealing. The term “vibe coding” was coined by Andrej Karpathy, who was also a founding member of OpenAI. As Karpathy describes, vibe coding is when you don’t think about code, you blindly trust whatever LLMs throws at you, and you vibe your way into building something. This approach to software development is made possible by how far language models have come (like Claude Sonnet), along with the rise of AI-powered editors such as Cursor and GitHub Copilot in VS Code. Vibe coding or not, coding with AI is quickly becoming the new default. Traditional software development has a steep entry barrier. You need to learn a programming language, grasp …  ( 4 min )

    Serverless Is a Lie (Unless You’re Using SQLite)
    We've twisted the word serverless into something vague. These days, serverless usually just means "I don't manage the infrastructure, someone else does." Which is fine. But it's also not the full picture. Because if we take the word literally (no server process to run, configure, or scale) then one database has quietly been the most serverless of all for over 20 years: SQLite. It doesn't run in the cloud. It doesn't need to connect to a remote API. It doesn't even require a boot-up process. It just works. And it's criminally underrated. Let's break this down into two flavors: This is the popular kind. You write your application and connect to a database that is fully managed by a third party. You don't worry about patching, scaling, or provisioning. Some examples: Firebase DynamoDB Neon Pl…  ( 5 min )

While we celebrate the productivity gains of AI tools, a more insidious process probably unfolds beneath - the surface—the systematic erosion of our fundamental technical capabilities. This is not pure speculation or technophobic fear-mongering; it is the reality playing out. The pattern is alarmingly consistent. A team adopts AI tools to enhance productivity. Initial results are impressive: faster code generation, quicker troubleshooting, more efficient documentation. Management celebrates the metrics.

    Async Is the New Superpower: Why Smart Developers Work Differently
    We all know the feeling. Suddenly your train of thought derails. You try to get back into flow, but it’s gone. Welcome to modern software development, where real productivity isn’t about working harder—it’s about working asynchronously. The Problem With Synchronous Everything Here’s the core issue: Synchronous communication assumes everyone is available at the same time. The difference is massive. If your team relies too heavily on live calls, pings, or "quick syncs," here’s what happens: Developers are constantly pulled from deep work Time zone mismatches create delays Pressure builds to be “always available” Creative thinking suffers due to fragmented focus As a developer, your job is to think clearly and build complex systems.

    Log Aggregation with Python: Bringing Clarity to Distributed Security Data
    As your cybersecurity toolkit grows, one concept becomes increasingly important—aggregation. Logs from a single server tell a story, but when you start working with networks of devices, cloud services, containers, and multiple endpoints, you quickly realize that analyzing one log file at a time is not enough. You need a way to bring those logs together, sort through the noise, and create a unified view of what is happening across your environment. That is where log aggregation comes into play. By collecting and combining log data from multiple sources, you can detect patterns, respond faster to incidents, and make informed decisions. In this article, we will explore how to build simple but effective log aggregation workflows using Python, and why it is a powerful step forward in your secur…  ( 6 min )
    Set Up a MongoDB MCP Server in VS Code Like a Pro
    🚀 What is the Model Context Protocol (MCP)? The Model Context Protocol (MCP) is an open standard introduced by Anthropic that aims to simplify how AI applications—like chatbots, IDE assistants, or custom agents—connect with external tools, data sources, and systems. Before USB, connecting devices meant dealing with dozens of ports and drivers. Similarly, integrating M different AI apps with N different tools used to require M × N custom integrations—a huge development burden. MCP changes that to an M + N model: Tool creators only need to build 1 MCP server per tool App developers only need to build 1 MCP client per application 🧩 How it works MCP follows a client-server architecture: Hosts: AI applications the user interacts with (e.g., Claude, an IDE, a custom agent) Cli…  ( 4 min )

    The Cloud Resume Challenge: a perfect way to explore the cloud
    I came across The Cloud Resume Challenge by Forrest Brazeal while studying for my AWS CCP exam, and without much thought, I added the website to my bookmarks. I was certain that at some point, I would take on the challenge, as it seemed like a great opportunity to gain hands-on experience with AWS. And… I did — after passing my exam, I started working on the project. At the very beginning, I had to set up my AWS personal development environment to ensure that my account (and my wallet!) was properly protected. To do so, I decided to use AWS Organizations. I created a "root" AWS account and set up an AWS Organization with an Organizational Unit (OU) inside it.

    🛠️ Today’s premium dev deal: AI SaaS Builder Kit + 7,000+ GitHub Projects → Instant Download Every developer has their own ecosystem: some use Bash, some live inside VSCode terminals, others flip between JavaScript, Docker, Makefiles, and Jenkins. It’s chaos—but productive chaos. I used to juggle a bunch of tools too. Until I realized something wild: I could replace all my scattered scripts, build tools, and dev automation with Python—and treat it as my personal glue layer for everything. Let me explain why this works, and how you can do it too. Modern dev workflows involve: Bash scripts for CLI automation JSON/YAML tools for config munging awk, sed, jq for data surgery Makefiles or npm scripts for building Cron jobs or CI pipelines for scheduling Docker/CLI tools for deployment None of t…  ( 6 min )
    Rethinking Front-End UX: Microsoft’s NLWeb and Natural Language Interfaces
    Web UX is having a moment. Not because of a new JavaScript framework (for once), but because of something much more fundamental: natural language as the interface itself. In early 2025, Microsoft introduced NLWeb, a project that brings conversational AI directly into websites via simple HTML attributes and JavaScript APIs. It's a shift that front-end developers and designers alike should be paying close attention to — because it fundamentally changes how users interact with the web. NLWeb is a Microsoft initiative designed to embed natural language interfaces directly into web experiences. Instead of rigid search bars or click-driven navigation, users can interact with a site using conversational queries — like asking a clothing store’s site, “Show me something under \$50 that's good for s…  ( 5 min )

    Practical Cases of Using the Singleton Pattern in Frontend Development
    The Singleton pattern is one of the most fundamental design patterns in software engineering, and it has several practical applications in frontend development. While often debated (as overuse can lead to issues), when applied judiciously, the Singleton pattern can solve specific problems elegantly in client-side applications. A Singleton is a design pattern that restricts a class to a single instance and provides global access to that instance. In JavaScript/TypeScript terms, it ensures that no matter how many times you try to create an instance of a class, you always get the same instance. Modern frontend frameworks often use Singleton-like patterns for state management: // Redux store (typically a Singleton) import { createStore } from 'redux'; import rootReducer from './reducers'; con…  ( 5 min )

    DSA Chronicles Day 4: Hashing & Stacks Continued
    Today was a solid day — tackled 4 more problems that deepened my understanding of hashing and stack-based logic. Covered some variety: hash frequency, prefix sum tricks, and even a stack-based temperature-wait problem. Here’s the breakdown: Problem: Prior to being passed to your function, nums is possibly rotated at an unknown pivot index k (1 <= k < nums.length) such that the resulting array is nums[k], nums[k+1], ..., nums[n-1], nums[0], nums[1], ..., nums[k-1]. For example, [0,1,2,4,5,6,7] might be rotated at pivot index 3 and become [4,5,6,7,0,1,2]. Given the array nums after the possible rotation and an integer target, return the index of target if it is in nums, or -1 if it is not in nums.

    Do you know how it works? - Higher Order Functions (HOFs)
    TL;DR: Higher-Order Functions (HOFs) are functions that receive or return other functions. They’re key to functional programming, widely used in React, map(), filter(), and more. They help abstract repetitive logic, making your code cleaner, testable, and elegant. Classic examples: setTimeout, Array.map(), Array.filter(), function factories. Higher-Order Functions (HOFs), or First-Class Functions, became a hot topic in JavaScript over the last few years — largely thanks to functional programming principles and React. But despite the intimidating name, HOFs are actually pretty simple. They can be defined as: Functions that takes one (or more) functions as parameters, or Functions that return another function But what’s the point of passing a function as a parameter?

    Why I'm Building 12 Projects
    I completed General Assembly’s Web Developer Immersive in 2016. Back then, the curriculum focused on Vanilla JavaScript, jQuery, raw Ruby, Ruby on Rails, and the MEAN stack (MongoDB, Express, AngularJS, Node). At the time, everything moved at breakneck speed—and while we covered a lot, I don’t think the fundamentals ever had time to really sink in. What I did admire was the program’s emphasis on building and deploying projects. You were thrown into the deep end—forced to wrestle with unfamiliar concepts and figure things out as you built. Pre-LLM, that approach made sense. You just pushed through and got something working. Whether that led to long-term understanding, though, was a different story. It wasn’t until I enrolled in CSMC 203: Introduction to Programming at Montgomery College that things finally began to click. That foundational class helped me breeze through CSMC 206: Python Programming, and from there, everything felt more grounded. Eventually, I transferred to the University of Illinois Chicago to finish my CS degree. Being at a large public university, many professors rely on autograders to evaluate code. Imagine your first programming project being run through HackerRank or LeetCode-style tests without ever really being shown how to solve a problem. It’s easy to see how that could be discouraging—maybe even enough to push someone out of the field entirely. And UIC? They pile on the homework, especially in the engineering department. There isn’t much space to breathe, let alone learn deeply, until the semester ends. I’ve been balancing work and school for a while now, and I finally have the time and mental bandwidth to prove what I’m capable of—not as a cog in an assembly line, but as a developer who builds with intention. Over the coming months, I plan to build and share 12 projects that demonstrate why I’m a senior developer—and why I’m qualified for just about any role I apply to.  ( 3 min )

    What is Typescript?
    TypeScript (abbreviated as TS) is a free and open-source high-level programming language developed by Microsoft that adds static typing with optional type annotations to JavaScript. It is designed for the development of large applications and transpiles to JavaScript. TypeScript may be used to develop JavaScript applications for both client-side and server-side execution (as with Node.js, Deno or Bun). Multiple options are available for transpilation. The default TypeScript Compiler can be used,[7] or the Babel compiler can be invoked to convert TypeScript to JavaScript. TypeScript supports definition files that can contain type information of existing JavaScript libraries, much like C++ header files can describe the structure of existing object files. This enables other programs to use th…  ( 4 min )

    I've created a text-to-form builder - feedback appreciated
    For several years form-data.com offered a forms-backend as a service, for people building their own static forms. Creating a form builder was an idea that I played with for a long time. However, as a developer I didn’t like most of the form builders out there. It always feels like I have to fill-in a (really complicated) form just to create a form. What I ended up with was a text-to-form builder. On the left you write simple text descriptor, and on the right you get a form. And of course, as with any product these days, you can just ask the AI to write it for you. Publish the form is simple, and you’ve got yourself a hosted form. And the backend gets all you’d expect from a forms the backend, including spam filter, email notifications, auto-response emails and integrations. I’d really appreciate if you give it a go and share any feedback - the studio is open without registration, and if you want to publish you need to signup without credit-card, and you get 100 free credits. Try it out here: studio.form-data.com Next step is releasing the cli so developers can manage the form descriptor as code in their own repo. You can see the studio in this youtube  ( 3 min )

    Ebirah Releases and Docker Image Pinning
    It is the 19th. of May 2025 and I am behind on my blogging schedule, I am actually behind on a lot of schedules. But let's see if I can catch up a bit. Yesterday I sat down to do a maintenance release of Ebirah 0.12.0, when looking at the repository I noticed that I had not tagged and released: 0.11.0, so with that out of the way I started to look at: 0.12.0. The primary focus was the update of the base image from Perl 5.40.1 to Perl 5.40.2. I had recently updated my Docker tooling, but without noticing any changes until now. My editor VSCode suggested that I pinned the Docker image to a specific version , a technique I have used and am using with GitHub Actions.

    10 Rendering patterns for Web Apps
    Web applications come in many different forms and use various rendering patterns to display content to the user. These patterns dictate how the application is built, how it is served to users, and how it interacts with the browser. In this blog post, we will explore some of the most common rendering patterns used in web development, including static websites, single-page applications, server-side rendering (SSR), static site generation (SSG), incremental static regeneration (ISR), hydration, partial hydration, islands, streaming SSR, and resumability. Static websites are the most basic type of web application. They consist of HTML, CSS, and JavaScript files that are pre-rendered and served directly to the user's browser. This means that every page on the website is a separate file, and eac…  ( 6 min )
    How I’m Learning AWS as a Beginner: What Finally Made Networking Click
    Starting my cloud computing journey with AWS Cloud Practitioner, I honestly struggled to grasp some of the concepts. Networking, IPs, even the general cloud terms, all felt new and overwhelming. Despite the struggles, I had already set a purpose: to understand why things work the way they do, not just memorize terms. So I started digging deeper apart from the AWS student guide, I watched YouTube explainers, reading more AWS docs, and learning from how experts on LinkedIn approach problems. One thing that helped a lot was reading how cloud professionals think about business needs of their clients, and how they approach AWS tools and services to solve them efficiently. Learning by Research & Reasoning CIDR and IP ranges Subnets and routing Internet Gateways and NAT Gateways I watched experts like NetworkChuck on youtube explaining how these connect in real cloud architectures, and attended a few expert sessions(like the ones from ALX) to build deeper understanding. I also documented everything on Notion, using toggles to organize concepts clearly and link them to real examples. Writing things out helped me make sense of abstract topics. Hands-On: Bringing It All Together After building that foundational understanding, I went hands-on with the AWS Console and practiced: Launching EC2 instances (choosing AMIs, instance types, configuring VPCs/subnets) Setting up IAM roles and using User Data scripts for automation Using key pairs and Git Bash to SSH into my instance Ran this command to verify the system: Got this output: 5.10.236-227.928.amzn2.x86_64 Amazon Linux 2 I explored basic Linux commands, storage configs, and how tagging and security groups improve structure and access. Progress Over Perfection I’m Curious… If you’ve walked the AWS learning path, what was your turning point? Was there a concept that “clicked” and made the rest easier? I Would love to hear how you approached your learning as a beginner or mentor. 👇  ( 4 min )

    Detecting and Fixing Vulnerabilities in Code Suggested by Cursor and Windsurf
    AI-powered code suggestions from tools like Cursor and Windsurf can introduce security flaws for several reasons. First, these models are built on extensive datasets that include publicly available code and third-party libraries, many of which already contain known weaknesses. As a result, the AI may inadvertently learn and replicate those insecure patterns. Additionally, these tools often produce predictable and repetitive code structures that, while syntactically correct, may be vulnerable to exploitation if not verified properly. Another key concern is their limited understanding of the broader application environment, including specific business logic or security policies, leading to code suggestions that may function correctly but pose risks when deployed.

    Artisan Commands You're Not Using (But Definitely Should)
    If you’ve worked with Laravel, you’ve typed php artisan serve php artisan migrate. And while those are useful, they barely scratch the surface of what Artisan can do. Artisan isn’t just a tool for running migrations or spinning up servers—it’s a command-line companion that can boost your productivity, simplify debugging, and teach you more about Laravel’s inner workings. Yet many developers (my past self included) tend to stick with the same 3-4 commands and miss out on some seriously powerful features.

    In-depth details of Class in JavaScript
    A class in JavaScript is a blueprint for creating objects. It allows you to define reusable object structures with properties and methods, making object creation and management more structured and efficient. JavaScript classes are a blueprint for creating objects. They introduce object-oriented programming (OOP) concepts like encapsulation, inheritance, and abstraction. Before ES6, JavaScript used constructor functions and prototypes to create and manage objects. With ES6, class syntax was introduced to provide a cleaner, more intuitive way to define object templates. JavaScript allows creating objects without classes using object literals, but classes provide advantages in scalability, maintainability, and reusability.

    Can Claude AI Generate Images? (As of May 2025)
    In recent months, Anthropic’s Claude AI has garnered attention for its robust conversational abilities and safe alignment strategies, yet it remains strictly a text-based model without native image creation features. Despite user curiosity and industry speculation, Claude’s image toolkit is currently limited to understanding and analyzing user-provided visuals rather than generating new ones. Meanwhile, leading competitors like OpenAI’s ChatGPT 4o (GPT-image-1) and Google’s Gemini continue to push forward multimodal capabilities, delivering sophisticated image synthesis alongside text output. This article examines Claude’s present functionality, explores the technical and ethical considerations behind its text-only stance, assesses the likelihood of future image-generation updates, and ben…  ( 6 min )
    The Real Challenges of Building with Rails and How Developers Can Overcome Them
    Ruby on Rails has earned its spot as a reliable, developer-friendly framework. For years, RoR has been the go-to for many startups and established tech teams alike. But let’s be honest, even Rails has its fair share of bumps along the way. Whether you're working on a brand-new project or diving into legacy code, there are some hurdles that Rails devs keep running into. Here’s a look at a few of those challenges and how our Rails experts at Railsfactory tackle them before they turn into full-blown roadblocks. As your Rails app grows, the cracks start to emerge. Queries slow down, page loads lag, and suddenly that once-speedy app starts to feel slow and sluggish. Most of the time, it's not Rails being slow, it's how the data's being handled. How we deal: At RailsFactory, we start with th…  ( 6 min )

    ✨ Understanding `AND (&&)` and `OR (||)` Operators in JavaScript
    Hello friends 👋 In this blog, I will explain two simple and powerful tools in JavaScript: the AND (&&) and OR (||) operators. These are called logical operators and are used to check conditions. Let’s understand them with examples that relate to real life 🚶‍♂️🍕💻 AND (&&)? The && operator checks if both conditions are true ✅✅ If both are true → result is true If any one is false → result is false ❌ Let’s say you want to go for a walk 🚶‍♀️ You will go only if: ➡️ It is not raining ☀️ AND ➡️ You have free time 🕒 let isNotRaining = true; let hasFreeTime = true; if (isNotRaining && hasFreeTime) { console.log("You can go for a walk! 🚶‍♂️"); } else { console.log("Stay at home! 🏡"); } 📌 If both conditions are true, the walk will happen 📌 If even one is false, no walk today! OR (||)? The || operator checks if at least one condition is true ✅ If one is true → result is true If both are false → result is false ❌❌ You will order food 🍔 if: ➡️ You are hungry 😋 OR ➡️ There is no food at home 🍳 let isHungry = false; let noFoodAtHome = true; if (isHungry || noFoodAtHome) { console.log("Order food online! 🛵"); } else { console.log("No need to order food. Eat at home! 🍽️"); } 📌 Only one condition needs to be true to order food ➡️ && → Both conditions must be true ✅ AND ✅ ➡️ || → Only one condition needs to be true ✅ OR ❌ let hasLaptop = true; let hasInternet = false; // Check if you can work from home if (hasLaptop && hasInternet) { console.log("You can work from home 💻🏠"); } else { console.log("You can't work from home 😕"); } // Check if you can still do something useful if (hasLaptop || hasInternet) { console.log("You can still be productive! 💡"); } Operator Result is true if... AND Both conditions are true ✅✅ OR At least one condition is true ✅ or ✅ I hope this blog helps you understand AND and OR operators in a fun and easy way! 😊 These are very helpful when writing conditions in JavaScript.

    What is Backend Development Architecture?
    Backend development architecture refers to the structural design and organization of the server-side components of a software application. It focuses on how the backend handles data processing, business logic, database interactions, authentication, API integrations, and server management to ensure scalability, security, and high performance. Modern backend architecture often leverages microservices, cloud-native infrastructure, containerization (like Docker and Kubernetes), RESTful and GraphQL APIs, and event-driven systems. Key trending concepts include serverless computing, API-first design, database optimization with NoSQL or NewSQL, and real-time data processing. This architecture plays a crucial role in building robust, maintainable, and scalable web and mobile applications that can handle complex user demands and evolving digital ecosystems.  ( 3 min )

    Using Trophy to build a gamified NextJS study app
    Gamification can be a really powerful feature of any educational platform. When done right, it’s proven by platforms like Duolingo and Khan Academy to consistently engage students and boost retention. The trouble is that a lot of the features that these platforms have made famous like achievements, streaks and progress report emails can take weeks to build. This is why we built Trophy, to help developers build these gamification features much faster. To demonstrate this I built an example web application that hypothetical students could use to practice flashcards.

    AI Engineering: The Meme, the Madness, the Motivation
    When Curiosity Strikes It always starts cute. You’re scrolling through LinkedIn, hear “AI is the future,” and suddenly your inner coder whispers: “Yeah, I’ll become an AI Engineer.” You open a YouTube tutorial, start learning Python, maybe dabble in a little scikit-learn... and for a moment, you feel invincible. Then Reality Hits Boom — you meet: Gradient Descent (why does it feel like I'm the one descending?) Backpropagation (stabbed in the back... with math) “CUDA not detected” (even though your GPU is flexing in Task Manager) Transformers (not the Optimus Prime kind ) Your innocent coding dreams become haunted by tensors and traceback errors. The Dev Setup, but Make it Chaotic You build your workstation: Dual monitors Fancy keyboard RGB lights Motivation? Fading... Mentally? Still in a baby playpen. Crying quietly as your LSTM forgets what it just learned. And Now You’re... Aged by 10 Years You started at 20. You debugged PyTorch for 3 nights. You now look like a retired philosopher sipping black coffee at 3AM. “I just wanted to make a chatbot…” But Here's the Truth... Every bug, every crash, every late-night meme scroll — it means you’re growing. So laugh at the chaos. Embrace the madness. Post the memes. Share the learnings. And keep going.

    Security is a Mess – How Plang Helps Fix It
    This post dives into Plang, an intent-based programming language that interprets natural language. For more, visit plang.is or get started here. Security is hard. As developers, we’re not exactly great at it. The issue is that security is binary - it either works 100% or it doesn’t at all. If there’s a flaw in your code, an attacker could gain full access to your system. Worse, you can never truly prove that something is 100% secure. All you can do is try to prevent every possible way in, which requires a lot of experience and a lot of eyes on the code. The only thing that gets you closer to 100% is time and scrutiny. That’s the key to secure code: experienced developers looking at it, lots of them, and enough time passing without a breach. We never know it’s secure. We can only hope. If I…  ( 5 min )

    I Took the Long Way Home to Code, and That’s Okay
    Hi, I'm Choice 👋🏽 I’m a Ruby on Rails developer with a background in chemistry — but really, I’m someone who’s rebuilding life from the inside out. My journey into tech wasn't linear. Like many Nigerians, I studied something safe (Chemistry), even though I’d always loved computers. Life happened, and I took detours that forced me to pause, reflect, and reimagine everything. Coding became more than a skill; it became a language of healing, structure, and hope. Since transitioning, I’ve built full-stack apps like ShopMe (e-commerce), DevConnect (developer community), and I’m currently working on TextMe, a real-time chat app. I’ve used tools like: Ruby on Rails (8), SolidQueue for background jobs AWS S3 for image storage React, Firebase, TailwindCSS, Bootstrap I’m also learning Django and Next.js 🌱 But beyond the tech, I’m creating soulful, user-centered projects — the kind that feel like quiet spaces on the internet. My content brand DearChoice is where I share faith, healing, and growth. My passion project Yardly aims to help communities in Nigeria discover local talents and preserve culture — online. I want to connect with devs who are learning with heart. Who are figuring things out slowly. Who care about the why, not just the how. If that sounds like you, let’s chat 🤝 Let’s build, share, reflect — and grow better together. ✨ 🧩 You can check out my projects on GitHub @ChoiceG 💼 And find me on LinkedIn See you around! – Choice 🌿  ( 3 min )
    Not Another UI Test: How API-First Testing Saved Our Pipeline
    If you've ever pushed a hotfix on Friday, only to get a bug report five minutes later… You know the pain of mobile testing. Between flaky UI tests, emulator delays, and device-specific weirdness, testing often feels like guesswork. We wanted something cleaner and found that API-driven mobile testing changes the game. Emulators that crash at the worst times Tests that pass locally but fail in CI Writing brittle UI test scripts that break on every UI tweak Hours wasted waiting for device builds to finish Sound familiar? We figured there had to be a better way - and there is. Instead of relying solely on UI flows, we started triggering mobile app behavior via APIs during CI runs. This gave us: More control over test execution The ability to skip the UI when not needed True automation across devices, even without a UI Turns out, you don’t need to “see” the app to know it’s working - you just need to test the right paths, fast. We integrated a lightweight API testing layer into our existing pipeline. We used a tool that let us: Run tests on real devices, remotely Trigger workflows from GitHub Actions Receive results via webhook Skip maintaining emulator scripts It plugged into our pipeline almost effortlessly, and we never looked back. Less flakiness Faster feedback Works across device types Easy to scale Most importantly, it lets us move fast without breaking things. We tried a few things, but ended up using tools like NativeBridge(the cheapest), Appetize, BrowserStack, and Lambda that made the API integration part smooth. No SDK installs, no heavy setup — just clean test runs triggered by API. We didn’t plan to switch our whole testing strategy, but it kind of happened naturally once we saw how stable and scalable it felt. You don’t need to rewrite your entire testing suite. Just look for places where API-driven checks can replace manual ones — and start small. It’s not about being trendy — it’s about not burning out your dev team maintaining flaky test code.  ( 4 min )
    Understanding CSS Transforms – A Beginner's Guide
    Today, I learned about CSS Transforms, and I’m excited to share what I discovered! The transform property in CSS lets you visually manipulate elements — you can move, rotate, scale, and skew them without changing the actual layout. It's super useful for animations, hover effects, and modern UI design. Here are some common 2D transform functions: translate(x, y) Moves an element from its original position. transform: translate(50px, 100px); rotate(angle) Rotates an element clockwise. transform: rotate(45deg); scale(x, y) Scales an element in the X and Y directions. transform: scale(1.5, 1.5); skew(x-angle, y-angle) Skews the element. transform: skew(20deg, 10deg); 3D transforms add depth to your elements and make them appear to move in 3D space. To view them properly, you often need to use the perspective property on the parent container. rotateX(angle) Rotates the element around the X-axis. transform: rotateX(45deg); rotateY(angle) Rotates the element around the Y-axis. transform: rotateY(45deg); rotateZ(angle) Rotates the element around the Z-axis (similar to 2D rotate). transform: rotateZ(45deg); translateZ(distance) Moves the element closer or farther away in 3D space. transform: translateZ(50px); perspective(n) Defines the distance between the viewer and the 3D element. .parent { perspective: 500px; } .box { width: 100px; height: 100px; background: teal; transition: transform 0.3s; } .box:hover { transform: scale(1.2) rotate(10deg); } When you hover over the box, it grows and rotates — all thanks to the transform property! CSS transforms (2D and 3D) are powerful tools that add creativity and interaction to your web designs. I enjoyed experimenting with different effects and seeing how elements can move and rotate on screen. Next, I’m planning to learn about CSS animations and how they work with transforms.  ( 4 min )

    Cartouche — a social network where you're the only human
    Hello everyone 👋 I’ve recently started building a personal open source project called Cartouche. It’s a one-user social network simulator. You write posts like on Twitter, and get reactions from hundreds (or thousands) of AI bots — each with memory, personality, and their own behavior. The idea Cartouche is a place to express yourself freely — without the pressure of real audiences. You get thoughtful replies, memes, debates, praise, skepticism, and support… but all of it from simulated users with their own quirks and styles. They react over time, not instantly. Some follow you, others unfollow. Some remember what you said weeks ago. Some adore you. Some argue. Some just drop a meme and vanish. It’s a space for testing ideas, exploring identity, or just yelling into a virtual crowd that somehow yells back — in meaningful, sometimes surprising ways. Why? Because sometimes you want feedback — but not from real people. What's built so far?

    Building a Retro Neo-Brutalist UI Library with Astro
    I've recently embarked on a fun project: launching a new website with a retro neo-brutalist 8-bit style using Astro. Rather than just building the site, I decided to take it a step further by creating a reusable UI component library that's maintainable for the long term. Say hello to astrobits.dev! It's still in its early stages, but I'm pretty excited about how it's shaping up. I've created GitHub issues for all the components I plan to add, giving me a clear roadmap for development. One decision I'm particularly happy with was implementing BEM (Block Element Modifier) guidelines for all the styles, enforced through linting rules.

    How Weaving Looms Led to Today’s Computers: A Simple History
    Have you ever thought about how the simple act of weaving cloth is connected to the computers we use today? It might sound surprising, but the story of computers begins with weaving looms! Long ago, people used looms to weave fabric. These looms created patterns by controlling how threads crossed each other. In the early 1800s, a clever inventor named Joseph-Marie Jacquard invented a loom that used punched cards to tell the machine which pattern to weave. These cards acted like instructions — telling the loom what to do step by step. This was one of the first examples of a programmable machine — a machine that could follow a set of instructions automatically. Around the same time, inventors were building machines to help with calculations. People like Blaise Pascal and Gottfried Wilhelm Le…  ( 4 min )

    What is Multimodal RAG
    There's a term out there in the AI community today that everybody's using: Multimodal RAG. Let's get this "RAG" out of the way before we dive into Multimodal RAG. RAG stands for Retrieval-Augmented Generation. Think of it like this: "Go find some helpful info, mix it with what you know, and then give me a smart answer." Here's the deal - you know those AI chatbots like ChatGPT that seem super smart? Well, they've learned tons of stuff, but they have some problems. Sometimes their knowledge is outdated, or when you ask about something really specific, they just shrug and say "Sorry, no idea." That's where RAG comes to the rescue. Before the AI answers you, it acts like a detective. It searches through fresh databases, company documents, maybe even the internet, to find the most up-to-date …  ( 8 min )

    Fast API Request Handling
    In FastAPI, how route handlers (endpoints) behave in terms of parallelism and concurrency depends on whether they are defined using async def or def, and whether the work inside them is I/O-bound or CPU-bound. Here are the four combinations of route handlers and how they affect parallel or concurrent handling of requests: async def with async I/O-bound work (e.g., await asyncio.sleep, database calls) @router.get("/async-io") async def async_io_route(): await asyncio.sleep(2) return {"status": "async io"} Handled concurrently Non-blocking — multiple such requests can be handled at the same time. Best performance for I/O tasks like DB queries, network calls, file access. async def with CPU-bound work (e.g., heavy computation, no await) @router.get("/async-cpu") async def …  ( 4 min )

    AWS Alert Validation - Lambda
    We are continuing the blog series about testing your AWS alarms. The first part of the series, which looked at CloudWatch actions and EC2 alarms, can be found here. An untested alarm is not one you can trust. This time we will look at alarms for your Lambda functions. As before, we will test the alarms by ”breaking” the Lambda so you get the same outcome as when a real issue would occur. Since this is Lambda, we will add code (or entire Lambdas) to make the Lambda act as we want. I will use Python, but the logic works for all the other supported languages. I have an examples repo where you can find Terraform code to deploy Lambas and required resources to AWS to test the alarms. You will need to connect your alarms to the Lambda functions, though.

    Building a Self-hosted IAM Platform to Add SSO to My Home Lab
    A growing problem with my home lab is password fatigue. Each time I add a new service to my network, I generate a new random password for it. I got by initially with using a different password for every service by storing them in a password manager, but as the number of services exceeded double digits, having to open my password manager every time I want to access each service is starting to hinder my productivity. I needed a self-hosted SSO solution for my home lab services, so I deployed an open-source IAM platform that supports SSO via OIDC, OAuth, and LDAP protocols to my Kubernetes cluster. The initial design was simple. I only needed SSO for my services, namely Grafana and Syncthing, and my solution must support both modern protocols like OAuth/OIDC and legacy protocols like LDAP.

    Which Compression Saves the Most Storage $? (gzip, Snappy, LZ4, zstd)
    Compression setting are set and forget in most cases, if it works no reason to change it.

I covered most of the algorithms discussed in this post previously in Compression Algorithms You Probably Inherited, where I summarized the info I collected while researching. But I wanted to sanity-check the findings myself and decided to run some benchmarks. This should help me see if compression actually makes a difference for storage costs. To keep things real, I used actual data: NYC TLC trip records. Each month’s data file was ~500MB. I combined a few to get files at 500MB, 1.6GB, 3.9GB, and 6.6GB.

    6 Best Open-Source Ticketing Systems for 2025
    Originally published at https://www.nocobase.com/en/blog/open-source-ticketing-systems. Last year, as the number of NocoBase users grew, we faced a pressing challenge: how to efficiently manage customer feedback and support requests. Users reached out via emails, community forums, and even through internal colleagues. With information scattered across multiple channels, issues were easily missed, and collaboration on follow-ups became cumbersome. We realized it was time to implement a ticketing system tailored to our workflows. So, we decided to build our own custom ticketing system using NocoBase. During this process, we tested several open-source projects and identified some excellent tools, while also defining the core features essential for an effective ticketing system.

    Schemas in PostgreSQL: A Practical Guide for Developers
    Schemas in PostgreSQL aren’t just for large systems—they’re for anyone who wants to keep their data structured. A schema is like a folder within your database where related objects (tables, views, etc.) are grouped together. This helps you separate concerns, organize logic, and secure your data more effectively. Here’s a practical look at how they work. Organization: Separate business domains (like inventory and users). Control: Limit access to different parts of your app. Maintenance: Make backups and updates more targeted. Cleaner Queries: Avoid clutter in your namespace. Comes with every PostgreSQL database. If you don’t specify a schema, objects go here. Created manually to isolate logic or control access. CREATE SCHEMA hr; How Data is Structured PostgreSQL Cluster └── Database └── Schema └── Tables, Views, Functions, etc. This layered model helps manage growing projects without chaos. CREATE SCHEMA inventory; CREATE TABLE inventory.products ( product_id serial PRIMARY KEY, product_name VARCHAR(255), price DECIMAL, stock_quantity INT ); CREATE TABLE public.users ( user_id serial PRIMARY KEY, username TEXT, email TEXT ); Using schemas lets you organize your app by responsibility—making it easier to evolve or scale parts of your system. Yes, and it’s a common best practice. Public is open by default; custom is restricted unless granted. Not directly, but they help manage large systems more cleanly. Yes, using tools like pg_dump or schema migration scripts. PostgreSQL schemas give you better structure, access control, and scalability. They're an essential tool for organizing your data without complicating your architecture. For a more detailed guide, visit the schemas in PostgreSQL article.  ( 17 min )

    Docker Like a Pro: Essential Commands and Tips
    Docker has revolutionized the way developers build, ship, and run applications. Whether you're a beginner or an experienced developer, mastering these essential Docker commands and tips will make you more efficient and productive. Before using Docker, ensure you have it installed by running: docker --version To get detailed system info, use: docker info Quickly run a container with: docker run -d -p 8080:80 --name my-container nginx This runs an Nginx server in detached mode (-d), mapping port 8080 on your machine to port 80 inside the container. To see all running containers: docker ps To include stopped containers: docker ps -a Stop a running container: docker stop my-container Remove a stopped container: docker rm my-container Remove all stopped containers at once: docker rm $(docker ps -aq) Over time, unused images take up space. Remove them with: docker image prune -a If you have a Dockerfile, build an image with: docker build -t my-app . This tags the image as my-app. Use interactive mode to execute commands inside a running container: docker exec -it my-container /bin/sh For Ubuntu-based containers, use /bin/bash. Monitor logs with: docker logs -f my-container The -f flag shows real-time updates. Copy files from your local machine to a running container: docker cp myfile.txt my-container:/app/ Copy files from a container to your machine: docker cp my-container:/app/myfile.txt . Instead of running multiple containers manually, define them in docker-compose.yml and start them with: docker-compose up -d Stop and remove all services: docker-compose down 💼 LinkedIn | 📂 GitHub | ✍️ Dev.to | 🌐 Hashnode Found this useful?

    Create a Custom React Hook to Persist URL Query Params with `react-router-dom`
    When working with query parameters in your React app, especially in tools like filters, pagination, or search inputs, you often want to persist those query parameters as users navigate across different views. In this post, you'll learn how to build a simple and reusable custom React hook using react-router-dom that preserves query parameters during route changes. Imagine you're on a URL like: /products?category=books&page=2 Now you click on a product to go to its detail page: navigate('/products/123') 💥 Boom! You lose your query params. When the user clicks the back button, they're dropped on /products instead of where they left off (/products?category=books&page=2). Let’s fix that by creating a useNavigateWithQuery hook. This hook wraps React Router’s useNavigate and useLocation to pr…  ( 4 min )

    React Animation Libraries in 2025: What Companies Are Actually Using
    1. Introduction "Ever scrolled through a modern dashboard and thought, ‘Damn! This feels so fluid… how do they do that?’" If you're a frontend developer in 2025, chances are you’ve asked yourself this at least once. Animations have quietly become one of the most influential parts of the user experience. They’re no longer just about making things "look cool"—they guide the user, provide feedback, and elevate interaction into engagement. In the early 2010s, animations were mostly afterthoughts—extra polish added at the end of a project if there was time. Today, they are baked into the design process from Day 1. With products competing for attention in milliseconds, smooth transitions, responsive feedback, and motion-based storytelling are the new UX fundamentals. But here's the catch—not a…  ( 8 min )

    How to Land a Coding Job in Post-Pandemic Times—The Untraditional Way
    I originally posted this post on my blog a long time ago in a galaxy far, far away. Last year, I sent out over a dozen of CVs and cold emails within a month. I was laid off. I went into panic mode. I applied to many companies. Anything with the word "coding" or "software engineering" in the job description. I even applied to a FAANG though I rejected that idea years ago. But I just got radio silence. I know because I wasn't the only one going through layoffs. The entire industry was. I even talked to an ex-coworker and he told me he had sent one hundred applications.

    Automate Website Monitoring with Python and Crontab on Linux
    Is your website or online service always available? In this article, you’ll learn how to build a simple monitoring script that checks a website’s availability every minute, logs the result, and lets you watch everything in real time with tail -f.

    Building a File Upload Time Estimator: Your Users Will Thank You
    Ever stared at a loading bar, wondering if you have time to grab coffee before it finishes? Here's a solution I built for that universal pain point. Try it now: Upload Time Estimator Last month, I was uploading a 2GB video project over a flaky connection. The browser gave me zero insight—just a spinning wheel of doom. "How long is this going to take?" I wondered. "Should I cancel and try later? Will it finish before my meeting?" That frustration sparked an idea. What if I built a tool that could predict upload times before users commit to them? We often overlook upload experiences in our applications. But for users, especially those with slower connections, this can be a major pain point. Consider these stats: 47% of users expect a web page to load in 2 seconds or less 40% will abandon a s…  ( 8 min )

    I Let an AI Coach Me for Dev Interviews. Here's How It Went.
    How an AI Interview Coach Helped Me Land My Dream Dev Job Let me start with this: I’ve always dreaded technical interviews. The whiteboard questions, the algorithm drills, the awkward silences when you blank out mid-sentence... it’s brutal. And when you're applying for dev jobs in a competitive market, even one bad round can cost you that dream offer. That’s why I decided to try something different. Instead of cramming alone or burning out on LeetCode marathons, I let an AI interview coach take over. Yep, I used a platform called OfferGoose — and spoiler alert: it changed everything.

    Understanding TypeScript: Inference, Types, and Generics
    Type Inference TypeScript can often guess types automatically. This is called type inference. When you assign a value without an explicit type, TypeScript infers it. For example: let count = 10; // inferred as number let message = "Hello"; // inferred as string The compiler knows count is a number and message is a string from these initial values. Type inference helps keep code concise and still type-safe. You don't always need to write : number or : string because TypeScript figures it out. Less code: You skip repetitive type annotations. Safety: Even with fewer annotations, TypeScript checks types. Readability: Code stays clean while avoiding obvious errors. However, you can still add type annotations if it makes the code clearer or if a variable’s type isn’t obvious. …  ( 6 min )

    DOJ is investigating Coinbase data breach— Report
    The US Department of Justice is reportedly conducting a probe over Coinbase’s contracted customer service agents in India, who accepted bribes in exchange for allowing criminals access to user data. According to a May 19 Bloomberg report, DOJ investigators are looking into the data breach, which Coinbase disclosed to the public on May 15. The exchange reported that a group of customer support contractors — subsequently fired — “abused their access to [...] systems to steal the account data for a small subset of customers.” “We have notified and are working with the DOJ and other US and international law enforcement agencies and welcome law enforcement’s pursuit of criminal charges against these bad actors,” said Coinbase’s chief legal officer, Paul Grewal, according to Bloomberg. Related: New Zealand man arrested in $265M crypto scam tied to FBI probe Though “no passwords, private keys, or funds were exposed” according to Coinbase, the data breach resulted in social engineering attacks targeting users, including a Sequoia Capital partner, with losses estimated at up to $400 million. The attackers also attempted to extort $20 million from Coinbase in exchange for not disclosing the breach, which the company refused. Backlash in the courts The attempted social engineering attacks have resulted in Coinbase users filing several lawsuits against the exchange, alleging that the company mishandled their personal data. One user, a retired artist named Ed Suman, reported losing $2 million to the scammers. Coinbase’s stock price fluctuated following the news of the breach and an unrelated probe from the US Securities and Exchange Commission over its reported “verified user” numbers.

    Circle plans IPO but talks with Ripple, Coinbase could lead to sale: Report
    Circle, the issuer of stablecoin USDC (USDC), is still planning an initial public offering (IPO), but the company is also in informal talks with Ripple and Coinbase about a sale, according to a report from Fortune. Circle is seeking at least $5 billion, which is its target for the IPO, according to the four banking and private equity sources Fortune cited. Ripple tried to purchase Circle on April 30, but the $4 billion to $5 billion bid was rejected as being too low. If Ripple or Coinbase were to buy Circle, the details of a purchase would differ. Ripple would pay using cash and XRP (XRP), a cryptocurrency that Ripple created. Coinbase, on the other hand, would use cash and stock. Coinbase and Circle have a relationship dating to 2018, when they launched the Centre Consortium. That ventur…
    Bitcoin futures data aligns with BTC traders’ hope for new all-time highs
    Key takeaways: Bitcoin buying in the spot and futures markets helped BTC price keep its upward momentum despite $170 million in margin liquidations. Weak stablecoin demand in China and the limited use of futures leverage suggest Bitcoin’s current rally is sustainable. Bitcoin (BTC) price has displayed strength at the $102,000 support level on May 19, following the $170 million in liquidations of leveraged positions. The abrupt $5,000 correction after hitting $107,090 may have been unexpected, but it does not mean the odds of reaching an all-time high in the near term are lower, especially since Bitcoin derivatives metrics have shown resilience.

    Before discovering Bitcoin (BTC), Ledn co-founder Mauricio di Bartolomeo found success shorting the Venezuelan Bolivar as it rapidly lost value against the stronger US dollar.

    Bitcoin ignores Moody’s US debt downgrade, rallies back to $105K after profit-taking sell-off
    Key takeaways: Bitcoin recovered from its sharp sell-off from $107,000, suggesting it functions as a hedge against uncertainty for investors reacting to Moody’s recent downgrade of US debt. Moody’s downgraded the US credit rating to Aa1, citing a $36 trillion debt and rising deficits, causing market turbulence and a spike in US Treasury yields. Despite short-term pressure from macroeconomic shifts, Bitcoin’s long-term outlook remains bullish due to cautious shorting and a weakening US dollar.

    Australian court ruling could lead to $640M in Bitcoin tax refunds
    A court decision in Australia could open the door to as much as $640 million in capital gains tax (CGT) refunds on Bitcoin transactions after a judge ruled that crypto should be treated as money rather than a taxable asset.  On May 19, the Australian Financial Review (AFR) reported that the decision arose within a criminal case involving federal police officer William Wheatley, who allegedly stole 81.6 Bitcoin (BTC) in 2019. At the time, the assets were worth roughly $492,000. At current market prices, the tokens are valued at more than $13 million. In the case, Judge Michael O’Connell of Victoria ruled that Bitcoin qualifies as a form of money rather than property, likening the digital asset to Australian dollars rather than to shares, gold or foreign currency. The interpretation could se…

    Crypto drainers as a service: What you need to know
    What is a crypto drainer? A crypto drainer is a malicious script designed to steal cryptocurrency from your wallet. Unlike regular phishing attacks that try to capture login credentials, a crypto drainer tricks you into connecting your wallets, such as MetaMask or Phantom, and unknowingly authorizing transactions that grant them access to your funds. Disguised as a legitimate Web3 project, a crypto drainer is usually promoted via compromised social media accounts or Discord groups. Once you fall prey to the fraud, the drainer can instantly transfer assets from the wallet. Crypto drainers may take various forms: Malicious smart contracts that initiate unauthorized transfers. Fake NFTs or token systems that create deceptive exchanges or assets. Cry…

    Vitalik Buterin proposes partially stateless nodes for Ethereum scaling
    Ethereum co-founder Vitalik Buterin unveiled a proposal to preserve trustless, censorship-resistant access to Ethereum, even as the network scales.  On May 19, Buterin shared a post outlining how to make Ethereum’s layer-1 scaling “more friendly” to users running local nodes for personal use. The Ethereum co-founder highlighted the importance of independent users running nodes, saying that a market dominated by a few Remote Procedure Call (RPC) providers risks censorship.  RPC providers let wallets, users and apps interact with the blockchain without running their own nodes. Crypto wallets are usually connected to an RPC provider behind the scenes. Buterin said there are risks to this setup.  “A market structure dominated by a few RPC providers is one that will face strong pressure to depl…

    ‘Sats’ vs ‘bits’ debate reignites amid proposal to change Bitcoin base unit
    A recent proposal that aims to change Bitcoin’s base unit to make it easier to understand as a payment tool has run into opposition, with critics saying Bitcoin’s satoshis are no more confusing than the dollar’s cents. Bitcoin developer John Carvalho introduced Bitcoin Improvement Proposal-177 on April 23, which seeks to eliminate the concept of satoshis, of which there are 100,000,000 in 1 Bitcoin (BTC), and effectively split Bitcoin’s fixed supply of 21 million into 21 quadrillion units. It follows a 2017 proposal from Bitcoin developer Jimmy Song to create “bits,” representing one-millionth of 1 Bitcoin. However, Carvalho said Song’s approach would still require Bitcoin users to think about decimals and “shifts complexity rather than eliminating it.” Block Inc. CEO Jack Dorsey is among…
    Coinbase faces lawsuit over alleged breaches of Illinois biometric privacy law
    A group of Coinbase users from Illinois have filed a class-action lawsuit against the crypto exchange, alleging that its identity checks violate the state’s Biometric Information Privacy Act (BIPA). Plaintiffs Scott Bernstein, Gina Greeder and James Lonergan claimed in the May 13 lawsuit filed in a federal court that Coinbase’s “wholesale collection” of faceprints for its Know Your Customer requirements violates BIPA, as they weren’t notified. The group claimed Coinbase failed to notify users in writing of the collection, storage, or sharing of their biometric data and the purpose and retention schedule for their data. “Coinbase does not publicly provide a retention schedule or guidelines for permanently destroying Plaintiffs’ biometric identifiers as specified by BIPA,” they alleged.  The…

    Australian feds seize mansion, Bitcoin allegedly linked to crypto exchange hack
    An Australian man from the state of Queensland has forfeited Bitcoin, a waterfront mansion and a Mercedes-Benz car after Australian Federal Police claimed the assets could be linked to the proceeds of crime. The AFP-led Criminal Assets Confiscation Taskforce (CACT) said in a May 18 statement that it seized nearly 25 Bitcoin (BTC), alongside the mansion and car, which are together worth a total of 4.5 million Australian dollars ($2.88 million). The AFP said its investigation began in September 2018 after law enforcement in Luxembourg shared information about suspicious Bitcoin transactions that the agency claimed were connected to the Queensland man, who was previously convicted of hacking a US gaming company.

    Russia arrests Blum co-founder Vladimir Smerkis on fraud charges
    Vladimir Smerkis, a co-founder of the Telegram-based crypto project Blum, has reportedly been arrested in Moscow, Russia, on fraud allegations, amid Blum confirming he is no longer affiliated with the project.

    How to Convert EPS to PNG: A Developer’s Guide
    EPS vs PNG: What’s the Difference? EPS (Encapsulated PostScript) is a vector file format used mainly for print workflows and high-quality graphics. It retains shape, curve, and scaling data—great for logos and illustrations. PNG (Portable Network Graphics) is a raster format ideal for digital content. It supports transparency and lossless compression, making it perfect for websites, apps, and UIs. So why convert? Because: Browsers don’t support EPS natively PNG is lighter and easier to preview You might need thumbnails or web-friendly versions of design assets Python makes this easy using the wand library (a wrapper for ImageMagick): bash with Image(filename='logo.eps', resolution=300) as img: ImageMagick is a powerful command-line tool that supports EPS to PNG conversion out of the box: bash bash If you're building a web app or serverless function and don’t want to install heavy dependencies, consider these APIs: Cloudinary: Offers format transformation pipelines CloudConvert: Easy-to-use REST API ConvertAPI: Handles over 200 file types including EPS Here’s a sample request using CloudConvert: bash https://api.cloudconvert.com/v2/jobs \ Web apps that allow users to upload and preview logos or designs Automated pipelines for asset generation or optimization CMS tools that generate thumbnails or social previews from design files Whether you're writing a backend service or automating a design workflow, converting EPS to PNG is a straightforward but essential task. For local scripts, go with Python or ImageMagick. For cloud scalability, plug into an API. Got a preferred method or tip for EPS to PNG? Drop it in the comments or share it on GitHub.  ( 4 min )
    Beyond Promises
    Automation promises simplicity—tasks repeated flawlessly, outcomes consistently predictable, and infrastructure harmoniously stable. At the heart of these captivating promises lies idempotency , an elegant idea proclaiming that no matter how many times we run an operation, the result remains steadfastly unchanged. Yet, the shimmering promise of automation's reliability seldom matches reality. In the messy arenas of operational infrastructure, idempotency frequently escapes our grasp. Like a distant horizon, it coaxes and compels—but rarely feels fully attained. Why does the concept of reliable idempotency struggle when translated from whiteboards to production realities? The culprit is the capricious, ever-changing landscape of real-world infrastructure management. Consider a familiar scen…  ( 6 min )

    Building a MIPS Emulator (Part 1): Loading and Reading Raw Binary

I broke it down into three parts: Loading the binary code from a MIPS program Decoding the binary instructions Executing them At first, I didn’t even know how to load a file, let alone parse instructions. So that’s where I began. We need a binary file that contains MIPS instructions in raw binary format. There are other formats like ELF, but I chose to keep it simple with a .bin file.

    Why you should become a developer marketer (A cold invitation)
    Back then, there was just digital marketing. Then product marketing. We’d segment audiences, figure out what they need, fear, and want.

You learn their pain points. You plug into their workflow. You speak their language. And you earn the one thing that moves the needle: trust. I’ve written a lot about developer marketing. Most of it lives on The New Stack and Hackmamba. But I noticed something. Nearly every piece out there speaks to companies.

    Streamlining Decentralized Infrastructure with the Contextum CLI
    Contextum CLI is the tool that brings it all together for developers and operators. In this article, we explore the technical details of how this CLI empowers professionals to deploy, manage, and monitor MCP deployments efficiently. The Contextum CLI (ctxctl) is a command-line tool designed to interact with the MCP stack. It provides fine-grained control over deployment lifecycle operations including cluster initialization, node provisioning, configuration updates, monitoring, and teardown. The CLI abstracts low-level orchestration complexity. Under the hood, it wraps tools like Terraform and Ansible (or native equivalents) to provision infrastructure and bootstrap MCP nodes across global regions. ctxctl init --name dev-cluster --region us-east --nodes 3 ctxctl deploy --config config.yaml …  ( 4 min )

    Migrando koa-graphql para grahpql-http
    Recentemente eu desenvolvi o desafio da Woovi com Koa.js e GraphQL (link do projeto). Uma das especificações opcionais era o uso do graphql-http, substituto do koa-graphql, que está presente no playground disponibilizado. No entanto, me deparei com alguns problemas iniciais: diversas funcionalidades não estavam presentes no graphql-http, visto que ele é apenas uma implementação do GraphQL sobre HTTP, isto é, é simples e minimalista. Primeiro, por quê? Bom, principalmente, porque koa-graphql foi praticamente descontinuado e graphql-http deve ser utilizado ao invés disso. Tomei esta decisão baseada em uma discussão que inclusive recomendava o uso do yoga, uma alternativa mais completa para servidores graphql, no entanto, eu vi que seria completamente capaz de resolver apenas com graphql-htt…  ( 5 min )

    Hashmap status: done
    This week’s post is mainly based on the Hashmap project and is just a brief summary of the project as I did not keep very detailed records, due to many setbacks I had for numerous reasons. I completed the Hashmap project I realised that I hadn’t used node.js to do the Linked List project (and I should have), so for this project, I did not use an index.html and ran my file using node.js from within Visual Studio Code. In order to do this, I had to use VSC debugger and I had to admit that I found it tricky at first. Sometimes nothing happened when I stepped through the code, sometimes nothing got displayed to the console, but I persisted with it and managed to figure out enough to be able to debug and create a working program. I had a lot of problems using the ‘this’ keyword, which intr…  ( 4 min )

    Threat Modeling Meets Test Planning: A Unified Workflow for Secure Code
    We often treat threat modeling and test planning as two separate disciplines. One belongs to the security team and lives in architecture diagrams. The other belongs to QA and rides shotgun with feature delivery. But in a world where security flaws are more business-critical than ever, this division doesn’t make much sense anymore. What if we stopped treating threat modeling as a theoretical security ritual and started using it as a blueprint for our test plans? What if the same mindset that helps identify potential attack vectors could also guide what we validate, automate, and protect in our test suites? Turns out, it can. Let’s be honest—most development workflows treat security as a checkpoint, not a mindset. You’ll hear “we’ve completed the threat model” during early planning. But week…  ( 5 min )

    🌍 Stop Timezone Chaos in Your Business App: A Laravel Developer’s Guide To Setup User TimeZone Based Carbon Usage
    Timezones are more than just a technical nuisance — they're a real threat to global businesses.

In this post, I’ll show you how I built a timezone conversion tool in Laravel that makes handling multiple timezones easy — even when your users span from Tokyo to Toronto. Let’s dive in. Imagine this: A user in Tokyo schedules a meeting at 2 PM local time. But someone in New York shows up at 1 AM because the app didn’t convert it right. 💀 Or worse: Calendar exports show incorrect times Daylight Saving Time changes break everything twice a year Manual conversions lead to bugs, missed events, and angry customers Sound familiar?

    Why Consistency Matters More Than Motivation (As a Developer)
    Originally published on Medium. Motivation is great — when it shows up. But consistency builds skills, habits, and portfolios. Some days I wake up inspired to build something new. Other days, I don't even want to open my code editor. If I waited for motivation to show up, I'd still be stuck at day one. Motivation is emotional. It depends on sleep, mood, weather, food, dopamine, whatever. It’s not stable. And that’s fine — we’re human. But if we rely on it to work, we’ll work very little. I’ve lost count of how many times I told myself: “I’ll do it tomorrow when I feel more ready.” That tomorrow rarely came. Consistency doesn’t rely on feelings. It’s a system. A rhythm. A muscle. One commit a day One blog post a day One small bug fix Even when it’s not perfect, or exciting, or ideal — it adds up. I stopped overthinking I built projects faster I became more confident I got better — not in a dramatic way, but quietly, steadily Even this blog you’re reading — it exists because I chose to write daily, not when I “felt inspired.” “Write for 15 minutes.” “Fix one component.” Something so small, it feels easy to do — and hard to skip. I don’t care if today’s task is small or ugly. I care that I showed up and made a move. When it comes, I enjoy it. When it’s gone, I work anyway. Motivation is a great bonus. But consistency is what builds portfolios, opens doors, and turns beginners into professionals. Don’t wait for the right moment. Build the rhythm that brings progress — no matter how you feel. Do you rely on motivation, or do you have a system that keeps you moving? Let’s compare notes in the comments. ✍️ Written by @denizgokbudak Frontend developer sharing thoughts on discipline, AI, and real-world dev workflows.  ( 4 min )

    How one bad coder made our stack unbreakable

The code commit comes in and suddenly half of staging is on fire. They push on main, forget semicolons, and somehow manage to brick a Docker container by renaming a folder. At first, we laughed. Then we cried. Then we made rules like “Nobody touches deploy unless it’s Monday–Wednesday, 9 to 5, and you’ve had coffee.” This person, let’s call him Dave, wasn’t just junior. Dave was entropy in human form. If there was a weak spot in the system, Dave would find it not on purpose, just as a side effect of existing. We called him the worst programmer on the team. But we were wrong. Because Dave didn’t just write questionable code he revealed where our system w…  ( 9 min )

    In-Memory Advisor in Oracle 23ai
    The In-Memory Advisor in Oracle 23ai analyzes database workloads to estimate DB-Time for various In-Memory sizes. Additionally, it can recommend which objects should be placed in the In-Memory column store. To use this feature, you must leverage the DBMS_INMEMORY_ADVISE package. The procedure for running the In-Memory Advisor is similar to the Privilege Analysis feature. To generate advice regarding In-Memory optimization, you first need to start a task and let it analyze the database workload. Once sufficient analysis has been performed, you can stop the task and review the generated report.

This is about a choice I made a few weeks ago: to become one of the top 100 AI/ML minds on the planet in the next 3 years. And I’m documenting everything. Every hour, every line of code, every mental breakdown, every rebuild. This is Day 1 of that journey. But it didn’t start today. In March, I joined offline coaching for Full Stack + AI/ML because YouTube wasn’t enough for me. I’m someone who learns best when I’m all in — environment, people, mindset. So I customized my learning path: Full Stack (MERN) My mindset shifted fast. From just wanting to stay ahead in college → to dominating my batch → to aiming at global level skill. That’s how I landed here. What I Did This Week This past week was about setting foundations — mentally, technically, and emotionally. My Weekly System (Moving Forward) Execution Stack: React.js + MongoDB coming next _ Posting Plan- _ I won’t be posting every day. I’ll post here once a week — just to keep it real and show exactly what I’ve built or learned. No fluff. Just raw execution logs, week by week. Closing Thought- I’m not doing this blog for likes. I’m writing this so that when someone 2 years from now wants to know how I did it — they won’t just see the success, they’ll see the system. No motivation quotes. No branding tricks. Just one guy documenting his rebuild. Let’s build.  ( 4 min )
    Why You Should Finally Move to the Cloud: A Practical Perspective Inspired by Bajaj Finance
    As the Head of Engineering at Bacancy, I often speak with businesses that are hesitant about moving to the cloud. They understand the benefits but worry about the complexity. What if the migration disrupts operations? What if costs go out of control? What if the existing infrastructure is too rigid to support the transition? These are valid concerns. But when a company like Bajaj Finance successfully moves its core lending platform to the cloud, it sends a strong message. If they can do it, so can you. This shift was not just a technical upgrade. It was a clear business decision aimed at making their infrastructure more agile, secure, and ready for growth. Bajaj’s move demonstrates that even the most critical systems can run better in the cloud. And they are not alone. We’ve helped several…  ( 6 min )
    trustthe.dev – A UI Component That Signs Your Work
    “We version packages, sign commits, and write changelogs — but our UIs stay anonymous.” That didn’t sit right with me. So I built trustthe.dev — a minimal UI component that makes your frontend self-describing. The component adds a small, persistent version tag to your UI, revealing: Package version (from package.json) Git commit hash, author, and message Repo + build branch Tech stack humans.txt link Structured schema metadata (ld+json) for the developer It’s SSR-safe, fully customizable, and built with shadcn/ui principles. Install it via the official shadcn CLI: npx shadcn@latest add https://trustthe.dev/r/version.json Then drop the component into your layout. 👀 Why? This isn’t a marketing badge. → Read the trustthe.dev Manifesto If you're a developer who versions, documents, and stands behind their work — this might be for you. 🚀 Next Try it live → trustthe.dev Feedback, forks, and feature requests welcome ✓ Trust the developer.  ( 3 min )

    Do you really know what yield return does?
    The use of yield return in C# has always been a bit of a mystery to me, but recently I’ve come to understand a bit better how it works and when it can be useful. Put simply, yield return allows you to generate values on demand as if they were part of a collection (IEnumerable), without having to manually create or populate a list. Items are returned one by one, only when needed, without storing them all in memory beforehand. Its main advantage lies in supporting lazy evaluation. Imagine you're working on a system that processes data from a large source (maybe a .csv file to be imported or even a .txt log file). In such cases, yield return can optimize memory usage, since it lets you load only one line at a time and begin processing immediately, without waiting to read the entire file. IEnu…  ( 6 min )

    What is UX?
    User experience design (UX design, UXD, UED, or XD), upon which is the centralized requirements for "User Experience Design Research" (also known as UX Design Research), defines the experience a user would go through when interacting with a company, its services, and its products. User experience design is a user centered design approach because it considers the user's experience when using a product or platform. Research, data analysis, and test results drive design decisions in UX design rather than aesthetic preferences and opinions, for which is known as UX Design Research. Unlike user interface design, which focuses solely on the design of a computer interface, UX design encompasses all aspects of a user's perceived experience with a product or website, such as its usability, usefulness, desirability, brand perception, and overall performance. UX design is also an element of the customer experience (CX), and encompasses all design aspects and design stages that are around a customer's experience.  ( 3 min )

    Say Goodbye to Payment Gateway Headaches: A Developer-Friendly SDK for East Africa 🚀
    Remember the sinking feeling? Not too long ago, while spearheading the development of an e-commerce platform with its heart set on the vibrant markets of East Africa, I slammed headfirst into the wall of payment gateway integration.

    Wait... Where Did My Margin Go? 🤯 (Margin Collapsing Explained)
    Do you see anything wrong in below image? 👀 No? 🧐 I have made a minor change do you see what I am talking about now? This is something that tripped me up recently — turns out it’s caused by a little CSS behavior called margin collapsing. 🤔 So, what is Margin Collapsing? As per MDN: The top and bottom margins of blocks are sometimes combined (collapsed) into a single margin whose size is the largest of the individual margins (or just one of them, if they are equal), a behavior known as margin collapsing. Note that the margins of floating and absolutely positioned elements never collapse. In simpler terms: This can make it feel like your margins are “disappearing” — which is exactly what I experienced! 🔧 How to Fix It? .parent { display: flex; /* or grid */ } 🌱 Why This Mattered to Me After some digging, I found this gem of a page: Mastering Margin Collapsing - MDN Highly recommended read if you’ve ever felt CSS was gaslighting you. ✅ TL;DR If vertical margins seem to “disappear”, margin collapsing might be the culprit Happens between block elements’ top/bottom margins Avoid it using display: flex, grid, or some padding Would love to hear if you’ve faced this before — or if this helped you spot a sneaky bug.

    A engenharia não falha a gestão sim: por que times excelentes precisam de gestão excelente

Foi nesse contexto que percebi como a gestão de projetos deixou de ser apenas uma função organizacional e passou a ser um pilar técnico. A engenharia precisa de autonomia, mas também precisa de direção. Não adianta termos um time que domina o React, o Kubernetes ou o GitHub Copilot se os ciclos são confusos, as prioridades mudam a cada reunião e as entregas perdem consistência.

    TWICK - React SDK for Building Video Editors (Captions, Timelines, Effects)
    I have been building a React-based video editing SDK tailored for apps that need to generate, edit, or enhance video content — especially AI-generated content like explainers, reels, and product showcases. As more AI tools pump out video content, one big pain point keeps surfacing: “How do we give users manual control over what the AI just made?” Most AI video tools can generate content — but they fall short when users want to fine-tune it. You get a video, but can’t easily: Add styled captions Adjust scenes Sync audio Edit the timeline Apply effects So I am building a toolkit that lets you embed an editing layer right into your frontend. Here’s a breakdown of what the SDK offers out-of-the-box: Media Utils Extract metadata (video, audio, images) Resize and fit media for different layouts Generate audio visualizers Extract audio from video Media Parser Convert .mov / .webm ➝ .mp4 Compress large video files Handle encoding seamlessly in the background Lambda Integration Export videos via AWS Lambda Save output directly to cloud storage (S3) Timeline Editor Trim, split, and arrange media layers Add & sync text, effects, and audio Timeline-based editing made React-friendly AI-Powered Captions Auto-generate captions from voice/video Apply styled caption themes Live Edit Canvas Drag, resize, rotate video elements Realtime sync with the timeline Live preview as you edit UI Visualizer Panel-based editor Built-in state management (with undo/redo) Effects Engine Canva-style animations: pop, flicker, fade, zoom Text effects: typewriter, staggered, bounce Visual filters for color grading & tone This SDK is ideal for: AI video generation tools (ChatGPT agents, script-to-video platforms) Social media automation apps Product marketing video builders Internal tooling for media teams Watch it in action?

    The secret to a long-lasting career in Software Engineering
    In recent times, with Cursor, lovable, and 101 other AI tools, I see many junior developers jumping on the AI bandwagon and just using generators to scaffold code. I also see a great deal of fear in the industry as well, fear that AI will take our jobs. The standards are becoming tougher, it's no longer enough just to know HTML+CSS and a backend language. To survive in modern times, you need to have a deeper understanding of programming and the tools in general. By attending a BootCamp and learning how to build something in [enter framework here], you most certainly can get a job in a few weeks or months' time. However, if you want to survive in the industry for 10+ years and beyond, you need to equip yourself with skills beyond what the market wants today. You should be able to pivot based on demand and grow as the industry changes. To do this, the best place to start is not the docs of [enter framework here]. Rather, it's computer science. Most of the industry has changed a lot in the past 20 years, but actually, the core concepts haven't changed much; thus, learning computer science will help you develop a strong, deeper understanding of how things work and therefore allow you to become a better problem solver. Having been around the block for more than 15 years, I have worked on many, many different problems of varying complexities. Many of these required me to draw on advanced programming and networking knowledge. Anyway, long story short 🙃 I'm working on a series of articles to go deeper into concepts we often ignore as web developers. My goal is to help upskill you into a more complete engineer (and also improve my knowledge too). here's the first article - understanding bits and bytes.  ( 3 min )

    You’re Using ShadCN Wrong ❌ – Here’s the Right Way to Customize It!
    ShadCN has taken the developer community by storm—and for good reason. It brings you beautifully built UI components powered by Tailwind CSS and Radix UI, ready to plug and play. But let me ask you something honestly... Are you using ShadCN the way it’s meant to be used? Chances are: No. I’ve been there too—dropping in components and rolling with the default styling, thinking “it looks good enough.” But here’s the truth: ShadCN is not meant to be used as-is. It’s designed to be customized! Let’s break down why most developers skip customization, what ShadCN is doing under the hood, and how you can easily customize it in minutes. There are two main reasons: It works out of the box – so we don’t need to tweak anything. It looks confusing under the hood – global CSS variables, HSL values, Tai…  ( 5 min )

They are designed to hold a modest amount of data specific to a particular client and website and can be accessed either by the web server or the client computer. This allows the server to deliver a page tailored to a particular user, or the page itself can contain some script which is aware of the data in the cookie and so is able to carry information from one visit to the website (or related site) to the next.

    Normal Coding vs. Vibe Coding: Which Style Speaks to Your Dev Soul?
    By Dhanian (@e_opore) Coding is more than just typing lines into an editor—it’s a craft, a puzzle, and for many of us, a deeply personal journey. Over time, I’ve danced between two wildly different approaches: normal coding—disciplined, logical, structured—and vibe coding—fluid, music-fueled, and sometimes beautifully chaotic. Both have shaped me as a developer. One grounds me, the other frees me. Today, I’m sharing their magic, quirks, and how you can find your rhythm between the two. Plus, I’ll introduce a resource I built to help you level up your style—available now on Gumroad. Normal Coding: The Architect’s Path Normal coding is like building a skyscraper with blueprints and permits in hand. It’s deliberate, precise, and designed to scale.

    The Subtle Corrosion of Code: How Gresham's Law Applies to Software Development
    In economics, Gresham's Law teaches us that "bad money drives out good." A powerful analogy, and surprisingly pertinent, permeates the daily life of software engineering: low-quality code tends to supplant well-crafted code. In a software development ecosystem often pressured by tight deadlines and continuous deliveries, the temptation to opt for quick and superficial solutions ("bad code") can become overwhelming. Although these approaches may offer short-term gains, they insidiously undermine the health and sustainability of our projects. The Mechanisms of Degradation: The "driving out" of good code by bad code is not a sudden event, but a gradual process driven by several factors: The Shortcut of Immediate Implementation: Under pressure, creating low-quality code, focused on the immed…  ( 5 min )

    What 117 Days of Reflection Taught Me About Writing Code That Lasts
    Read the full story here → What 117 Days of Reflection Taught Me About Crafting Code That Endures For 117 days, I've been writing a short reflection every morning. At first, it was just a quiet ritual. A way to center myself before diving into code. But over time, it became something else. I started noticing patterns in how I approached problems, how I rushed when I should have paused, and how often I worked around I should have worked through it. These reflections reminded me of the kind of developer I want to be. One who builds with care and writes code that stays strong when things get messy. Here are a few lessons that stuck: Each day, I pair a short insight with a quote from the Stoics. Not to sound wise, but to stay grounded. I'm sharing them here if you ever want to slow down for a minute: Daily Developer Reflections There's no secret to better code. Thanks for reading. If any of these ideas resonate with you, I'd love to hear what you've learned from your daily practices.  ( 3 min )
    How to analyze Java application performance with async-profiler in Amazon EKS
    Analyzing the performance of a full-stack application (Java and Angular) running on Amazon EKS requires a combined approach, as async-profiler is primarily focused on the Java backend. Async-Profiler is a low-overhead sampling profiler for Java applications running on the HotSpot JVM. For the Angular frontend, you’ll primarily rely on browser developer tools and potentially some Angular-specific profiling techniques. Container startup performance presents a significant challenge for Java-angular applications running on Kubernetes, particularly during scaling events and recovery scenarios. Performance profiling in containerized Java applications has long presented significant challenges.

    🚀 Kotlin's Key Features #1
    🏹 Null Safety in Kotlin Dodging the Null Pointer Exception, the Kotlin way🤓🤓 ➤ Concept of Strict Null Safety in Kotlin • Safe Call Operator ( ?. ) in Kotlin ( ?: ) in Kotlin ( !! ) in Kotlin. Kotlin allows to store “Null” values in a variable. In Kotlin, the variables can be made of Null types by just adding a “?” symbol to the right side of the data type. A nullable type variable means it can also hold “Null” as a value in it. A non-nullable type variable means that it can not hold “Null” as a value in it. The safe call operator is simply a question mark followed by a dot ( ?. ) The safe call operator in Kotlin, is one of the methods to impose “Null Safety Checks” on the nullable variables. If the left-hand side of the operator is null, then it will return null value. If the left-hand side of the operator is not null, then it will return the result of the right-hand side expression. The elvis operator is represented by a question mark followed by a colon ( ?: ) The elvis operator in Kotlin, is one of the methods to impose “Null Safety Checks” on the nullable variables. If the first operand is not null, then this operand will be returned by the elvis operator. If the first operand is null, then second operand will be returned by the elvis operator. The Not Null Assertion is represented by a double exclamation mark (!!) The Not Null Assertion in Kotlin, is another tool to deal with nullity. This operator explicitly casts nullable variables to non-nullable variables.  ( 3 min )

    The original motivation for creating Lean was software verification
    "The main motivation, the original motivation for (creating) Lean was in software verification, right? I mean, Z3 was very popular at bug finding, for bug finding at Microsoft, was very influential there. But (for) Lean the goal was, can we make the same, have the same success of software verification? We went to a very strange path. I mean, having impact in mathematics that we never dreamt of. But the goal in both cases is like we, both in software mathematics and in AI, today rely on manual review, partial testing. A mistake in a theorem can be catastrophic, invalidating the whole result. The same thing (happens) for a critical piece of software, right? And one thing I see all the time, people fearing to make a change a piece of software because they fear by making the change they may be introducing a bug, especially if it's a critical piece of software."

    Junior vs Mid vs Senior Developer: What’s the Real Difference?
    “Same title. Same job. Very different outcomes.” If you've ever worked on a dev team, you’ve probably noticed it: not all developers with the same title operate at the same level. Some juniors write better code than mids. Some seniors… well, are just loud middles. So what actually separates a junior developer from a mid-level or senior engineer? Is it years of experience?

    Why Linking your Test Scripts with the Test Management Tool is a Game-Changer!
    Let’s talk about something that often gets overlooked in the hustle of automation, syncing your automated test scripts with your test management system! You might think, “Eh, my tests run fine. I’ve got my green ticks on the pipeline. Why bother?” Well, hold onto that thought, because today I’m going to show you why this link is not just a nice-to-have but a superpower for your test automation efforts! What do I mean by Linking? At its core, linking means there’s a direct connection between the test cases you’ve written in your test management tool (like TestRail, Azure Test Plans, XRay, etc.) and the actual automation scripts you’ve coded up in your framework (Cypress, Playwright, Selenium — you name it). This sync can be manual (you link test IDs in your scripts) or fully automated. Wh…  ( 6 min )

    Rediscovering ACID – The Foundation of Reliable Databases
    As engineers, we use transactions all the time — BEGIN, COMMIT, and maybe a rollback if things go south. But recently, I realized I hadn’t truly internalized what makes those transactions reliable. That curiosity led me to revisit the ACID properties — a foundational concept we all learn early on but rarely pause to deeply understand. What started as a quick refresher turned into a deep dive into atomicity, consistency, isolation, and durability, and how real databases like PostgreSQL and MySQL implement them. Along the way, I discovered that one core mechanism — the Write-Ahead Log (WAL) — is key to both Atomicity and Durability, playing a foundational role in keeping transactions safe and recoverable. In this first part of a multi-part series, I’ll walk through what each property means, …  ( 5 min )
    Python for Oracle on ARM Linux | Part 2 - "shell like" SQL scripts
    { Abhilash Kumar Bhattaram : Follow on LinkedIn } NOTE : The blog examples is on ARM Linux but almost the same works for x86 if as long as you have the required miniconda environment. In traditional DBA workflows, shell scripts are commonly used to automate database tasks such as executing SQL files, capturing logs, and scheduling jobs. However, this blog demonstrates how Python can serve as a modern and powerful alternative to shell scripting for Oracle DBAs. By leveraging Python’s subprocess module, we show how to run SQL*Plus commands, manage SQL script execution, redirect output to spool files, and even handle background processes—all within a clean and maintainable Python environment.

    Avoid Memory Leaks in Angular When Using takeUntil with Higher-Order RxJS Operators
    When working with Angular and RxJS, takeUntil is a common operator for unsubscribing from observables, especially in component lifecycle management. However, if you're using takeUntil incorrectly with higher-order mapping operators like mergeMap, switchMap, concatMap, exhaustMap, you may still end up with memory leaks. A common mistake is placing takeUntil before a higher-order operator in your observable pipeline. This seems logical, but it doesn't always behave as expected. When takeUntil is upstream of a higher-order operator, it won't effectively unsubscribe the inner subscription created by that operator. this.counterB$.pipe( takeUntil(this.destroySubject), mergeMap((value) => this.counterA$) ).subscribe(...); In the example above, the outer observable (counterB$) is unsubscribed…  ( 4 min )

    What is GO
    GO or GOlang Introduction Go(or GoLang) is a popular low-level programming language developed by Google in 2007. And that's what we are going to cover in this blog. What is GO? How was it developed? Why should you consider learning GO? So let's not waste our time and jump in. GO is a general-purpose programming language. It is statically typed and compiled. It is known for its simplicity of syntax and a better developer experience than other programming languages in the same niche, like: C C++ Rust A statically typed language is one where the type checking is completed at compile time, meaning the data type of each variable (string, integer, etc.) is known before the program runs and cannot be changed afterwards. Many people get confused and think that GO is both statically and dynamically typed because: x := 2 //Dynamically declared (GO's Type interface decides the type). var y int = 4 //Statically declared. Both ways can be used to declare variables in GO. But then why do we say it's statically typed? Because in a statically typed language like GO, you cannot do: x := 2 and then x = "two". Doing this will cause a compilation error. But in dynamically typed languages like JavaScript, you can do the same thing as x = 2 x = 'two' console.log(x) And it will work fine. GO was developed by Google in 2007. The designers wanted to address the issues they felt with the language they used at that time, but keep their useful characteristics. Go was publicly announced in November 2009, and the first version was released in 2012. Now, this language is actively used in the world. It’s Simple and easy, unlike Rust, C++, and C. First Class Concurrency Performance Proven Track Record + Job Demand And that's why you should prefer learning GO.

    How does quoting works in ArkScript macros?
    The other night, I was talking about meta programming to other developers, and at one point someone asked how macros could be used to do meta programming. They were probably thinking about C type of macros, which are powerful but are just text processor tools. Using macros you could have the following code: double Compute() { // doing something return result; } and transform it into: double Compute() { if (_cache.GetValue(out var result) return result; // doing something _cache.SetValue(result); return result; } They are a tool to manipulate code, with code. It allows one to write generic code and have the compiler do the heavy lifting and monomorphize your code. What's meta programming?

    Why I’m Building a Dopamine Tracker
    In early 2025, I realized something uncomfortable: I was spending hours every day switching between tabs, endlessly scrolling, and jumping between distractions — and I didn’t even realize how often it was happening. Like many developers and students, I use a computer all day. But I noticed a pattern of compulsive behavior that wasn’t productive. I wasn’t just “working online.” I was switching contexts 50+ times an hour — email, YouTube, Reddit, docs, social media, GitHub… repeat. I wanted to understand my dopamine loops — those invisible triggers and habits that push me to seek micro-hits of pleasure instead of focusing on deep work. That’s why I started building Dopamine Tracker — a minimal, privacy-focused tool that: tracks online behavior via a browser extension, stores it in a Supabase backend, and visualizes patterns through a React dashboard. It’s not about guilt or blocking websites — it’s about insight and agency. Right now, the extension logs: Active tab time App switches and focus changes Time-of-day usage Top “dopamine drivers” (based on frequency + context) Everything is stored locally in local storage as for the alpha stage. I’m sharing this journey to: document the technical process (React, Supabase, browser APIs), reflect on design choices and architecture, connect with others working on similar problems. If you’ve ever found yourself working but not really working — this project might speak to you. In the coming weeks, I’ll share devlogs on: implementing dopamine tracking and scoring algorithms designing the extension UI, building the analytics dashboard, Thanks for following along. Let’s see where this goes. Stay mindful, stay focused. — Pietrell  ( 3 min )

    MCP Is to AI What REST Was to the Web: Understanding the Model Context Protocol
    Introduction The next generation of AI assistants is here — and they’re not just smarter, but far more connected. At the heart of this evolution lies the Model Context Protocol (MCP), an open standard introduced by Anthropic in November 2024. Much like how REST transformed the web by standardizing communication between services, MCP aims to do the same for AI by enabling seamless, scalable access to data and tools across platforms. Why We Needed MCP Despite their sophistication, most AI models operate in isolation. Critical information is often trapped in disconnected silos — internal databases, legacy systems, and proprietary tools. Integrating AI assistants with these sources required bespoke connectors, resulting in the infamous N×M integration problem: every new model needed custom cod…  ( 6 min )
    Deep Copy vs Shallow Copy in JavaScript: Complete Guide
    Understanding Object References in JavaScript Have you ever changed something you thought was a separate copy, only to find you messed up the original data too? Yeah, that happens a lot if you don't get how JavaScript handles different kinds of copying; deep copy vs shallow copy. JavaScript has these two main ways it thinks about data: by value and by reference. Simple stuff like numbers, strings, booleans, null, and undefined are value types. When you copy them, JavaScript just makes a whole new one. A separate thing entirely. Changing the new one never affects the old one. let a = 10; let b = a; // b gets a copy of the value 10 b = 20; console.log(a); // Output: 10 (a is unchanged) However, objects, arrays, and functions are reference types. When you assign one variable to another, yo…  ( 10 min )

    😄 Built a fun little project to calculate how ancient you are... and sneakily learned Docker in the process!
    This is a basic Go lang project that shows your age if you know your birth year. In this, you have to input your birth year, and it will take the current year automatically. By using the formula Current Year - Birth Year, it shows your current age. This project is mainly intended to learn how to containerize an application. It is not a Go-focused project but mainly Docker-focused instead. A Dockerfile will be created to build a Docker image and run it inside a container. Once containerized, the application can be run easily using Docker commands on any system that supports Docker, regardless of the host environment. This helps demonstrate the power of containerization and the portability it brings to software development. The project will also serve as a base to practice Docker fundamentals like: -> Writing a Dockerfile -> Building a lightweight image for a Go application -> Running the image as a container -> Understanding how to manage input/output inside the container Overall, this project provides a practical, beginner-friendly example of containerizing a simple application — making it a great starting point for learning Docker and DevOps workflows. Setup and Usage https://github.com/kartik-paliwa1/Know-Your-Age 📝Step 2: Create a Dockerfile: WORKDIR /app COPY . .

    7 Programming Mistakes I Made That Almost Destroyed My Projects (And How I Fixed Them)
    Everyone tells you how to write perfect code. But no one tells you how easy it is to mess things up, especially when you're just starting out. 1. Writing Code Without Planning Anything: I jumped straight into coding because I was too excited. The Result: Now, I sketch out a quick plan, even 10 minutes of thinking saves hours of debugging. 2. Copy-Pasting Stack Overflow Without Understanding: I copied a solution that worked—until it didn’t. The Result: I still use Stack Overflow, but I make sure I understand every line I paste. 3. Ignoring Git Until the Last Minute: I lost an entire day’s work because I forgot to commit. The Result: I commit after every major change and push regularly. Git is now my safety net. 4. Not Reading the Documentation: I wasted hours searching for answers that were literally in the first paragraph of the docs. The Result: First I read the docs, then surf the internet for information. Even the order of this matters. 5. Overengineering Everything: I tried to build “the perfect solution” with 10 extra features I didn’t need. The Result: Build version 1 very simple. Improve later. Launch ugly, improve fast. 6. Not Asking for Help: I stayed stuck on a bug for 3 days because I didn’t want to “look dumb” by asking help. It was a terrible mistake. The Result: I now ask questions early—online, Discord, dev forums. No shame in learning. 7. Testing Code in Production: I pushed code live without testing. The Result: I test locally, then deploy to staging, then go live. Never gonna skip testing again. Final Thoughts: Which one hit you the hardest? Drop it in the comments.  ( 4 min )
    Push Notifications: How Your App Speaks When It’s Sleeping
    What are Push Notifications ? Push notifications are messages sent from an app or website to a user's device, even when the app or site isn’t actively open.

    Avoiding the God Object - A Guide to Better Software Design
    In software design, a God Object (or God Class) is a class that knows too much or does too much. It's a common code smell that tends to emerge as a system evolves without proper boundaries. A God Object violates the Single Responsibility Principle by taking on multiple responsibilities. It typically centralizes control and knowledge of many parts of a system—handling tasks that should be delegated to other specialized components. Even experienced developers can fall into this trap, usually due to: Moving fast: Prioritizing speed over modularity in early stages. Avoiding perceived complexity: Putting logic in one place “for convenience.” Fear of breaking things: As the class grows, refactoring becomes scarier. Lack of clear ownership boundaries: Developers aren't sure where logic belongs. L…  ( 4 min )
    ⬜️ AI told me to move to Estonia, so I’m eating bread now
    This isn’t a record of migration. It’s just me, chewing on bread. I was born and raised in Japan. One day, I decided to ask GPT GPT didn’t hesitate. …Estonia? I laughed a little. So I asked GPT a few more questions. I still don’t really know much about Estonia. Also— IT as a form of defense Not one pillar, but many Language as the core of thought Arvo Pärt’s music touches my brain The flag is just cool (bonus) I still don’t know much. And freedom there felt quiet, but intentional. ...Maybe I imagined all of it. I don’t speak English. Also—just a hunch, So I did the most logical thing I could think of: Is this serious? A joke?

    The Law of Attraction vs The Algorithm of Attention: Are We Manifesting or Just Being Tracked?
    “If you focus on something long enough, it will come to you.” Sounds like the Law of Attraction, right? But in 2025, this has a whole new face — and it’s powered by AI algorithms. The idea is simple: Focus your mind on what you want. The universe will align to make it happen. Believers say: 易 “Thoughts become things.” Let’s bring in Instagram, Facebook, or YouTube: Don’t like a post? No problem. Just pause for a few seconds, and BAM — the algorithm picks it up. Now your feed is filled with related posts, ads, and suggestions. It feels like magic. But it’s not. Every interaction you make: Scroll Click Pause Comment …is stored, tracked, and processed. The algorithm uses machine learning to analyze your behavior — and shows you more of what you seem to like. Just like “manifesting,” right?

    VarMQ Tuning Worker Pool
    I've created a "tune API" for the next version of VarMQ. Essentially, "Tune" allows you to increase or decrease the size of the worker/thread pool at runtime. For example, when the load on your server is high, you'll need to process more concurrent jobs. Conversely, when the load is low, you don't need as many workers, because workers consume resources. Therefore, based on your custom logic, you can dynamically change the worker pool size using this tune API. In this video, I've enqueued 1000 jobs into VarMQ, and I've set the initial worker pool size to 10 (the concurrency value). Every second, using the tune API, I'm increasing the worker pool size by 10 until it reaches 100. Once it reaches a size of 100, then I start removing 10 workers at a time from the pool. This way, I'm decreasing and then increasing the worker pool size. Cool, right? VarMQ primarily uses an Event-Loop internally to handle this concurrency. This event loop checks if there are any pending jobs in the queue and if any workers are available in the worker pool. If there are, it distributes jobs to all available workers and then goes back into sleep mode. When a worker becomes free, it then tells the event loop, "Hey, I'm free now; if you have any jobs, you can give them to me." The event loop then checks again if there are any pending jobs in the queue. If there are, it continues to distribute them to the workers. This is VarMQ's concurrency model.  ( 3 min )
    Mastering Mouse Events in React + TypeScript: Click, Drag, Hover and Beyond

    🧠 Beyond Code: The Real Life of a Software Engineer
    When people hear "software engineer," the first image that pops into their mind is someone furiously typing code, probably in a dark room with six monitors and a cup of cold coffee. But is that all there is to it? Not even close. In this post, let’s explore what it really means to be a software engineer — beyond the code. Being a great software engineer isn’t just about knowing 12 different JavaScript frameworks. It's about understanding problems and communicating solutions. Can you explain a complex bug to your product manager in simple terms? Can you write clear, helpful documentation? Can you give constructive feedback in code reviews? 💡 If you're not improving your communication skills, you're limiting your growth. You’ll often face challenges that have nothing to do with code: Ambiguous requirements Legacy systems with no documentation Interpersonal team conflicts Sometimes, you spend more time on Slack than in VS Code. And that’s okay. That’s part of the job. You don't just learn programming languages — you learn people, processes, and priorities. The most successful engineers I've met are not the ones who knew everything — but the ones who kept learning every day. Burnout is real. Sleep deprivation doesn’t make you a hero. Take breaks. Set boundaries. Eat lunch away from your screen. Because your brain is your best asset — and it needs rest to work its magic. Software engineering is a journey — and the code is just one part of it. The next time someone asks you what you do, don’t just say "I write code." Because that’s what you really do. 💬 What’s something you've learned outside of code that made you a better developer? Drop your thoughts below — let's talk!  ( 4 min )

    My Journey with RSI
    My Journey with RSI A story about my experience with finger pain and how I overcame it. Every situation is different, but I hope this helps or informs you. The first half of the post is a weekly account of the experience and my attempts to fix this bug. The second half is the solution I found and the lessons learned. TLDR: If you want to jump straight to the climax and resolution, skip to The worst week - and the turning point (week 13) Trigger condition: Was walking to work in 7c winter mornings without wearing gloves or a jacket, followed by typing right afterward. At this time, I was writing 29 ESLint rules & accompanying tests (compared to regular coding, this involves more typing and fewer breaks for thinking). Typing for 9-12 hours a day, 7 days a week. In retrospect, I should have s…  ( 12 min )
    Types of dependencies in package.json file
    Let’s break down each type of dependency in package.json in detail: Dependencies ("dependencies") These are the essential packages required for your project to run in production. They are installed automatically when you run npm install or yarn install. Example: If you're building a React application, react and react-dom would be dependencies. Defined like this in package.json: "dependencies": { "react": "^18.0.0", "redux": "^4.1.0" } When you deploy your application, these packages are included. DevDependencies ("devDependencies") These packages are only needed during development (e.g., testing tools, linters, build tools). They won’t be included in the production build. Example: Testing frameworks like jest or bundlers like webpack. Installed with: npm instal…  ( 3 min )
    Operadores Bitwise em Golang
    Nos últimos dias venho estudando a linguagem Go e me deparei com um assunto que achei muito interessante: os operadores bit a bit. Como eu ainda não os conhecia bem, resolvi compartilhar o que aprendi com vocês. Além dos operadores de comparação já conhecidos && (E), || (OU), > (Maior que), etc., Golang possui assim como em outras linguagens os operadores bitwise, que são representados pelo símbolos &, |, ^, >>, representação binária final fmt.Println("a> - deslocamento à direita (right shift) Desloca os bits de a para a direita, descartando os bits da direita. // a = 0110 // a = 0110 >> 2 // a = 01 // a = 0001 -> representação binária final fmt.Println("a>>2: ", a>>2) // 1 E aí, gostou?

    `pnpm` setting steps
    Why use pnpm Faster then npm More dist-efficient (uses symlinks and a content-addressable store) Strict by default (prevents dependency hoisting issues) pnpm npm install -g pnpm pnpm init This command creates a package.json file. Add a package: pnpm add Add a dev dependency: pnpm add -D Example: pnpm add react pnpm add -D typescript ts-node In package.json, define scripts like this: { "scripts": { "start": "node main.js", "dev": "vite" } } Then run pnpm start pnpm dev pnpm install (Shortcut: pnpm i) Remove a package pnpm remove Update packages pnpm update List installed packages pnpm list pnpm: pnpm creates a pnpm-lock.yaml instead of package-lock.json. If you're using a monorepo, pnpm handles it differently (via workspaces). You might want to delete node_modules and package-lock.json before switching to avoid conflicts: rm -rf node_modules package-lock.json pnpm install  ( 3 min )
    1931. Painting a Grid With Three Different Colors
    1931. Painting a Grid With Three Different Colors Difficulty: Hard Topics: Dynamic Programming You are given two integers m and n. Consider an m x n grid where each cell is initially white. You can paint each cell red, green, or blue. All cells must be painted. Return the number of ways to color the grid with no two adjacent cells having the same color. Since the answer can be very large, return it modulo 109 + 7. Example 1: Input: m = 1, n = 1 Output: 3 Explanation: The three possible colorings are shown in the image above. Example 2: Input: m = 1, n = 2 Output: 6 Explanation: The six possible colorings are shown in the image above. Example 3: Input: m = 5, n = 5 Output: 580986 Constraints: 1 <= m <= 5 1 <= n <= 1000 Hint: Represent each colored column by a bitmask based on each cell co…  ( 26 min )
    Why I Design Like a Bit — Thoughts from a Structure-First Dev

    Understanding DNS: How Domain Names Become IP Addresses
    Understanding DNS: How Domain Names Become IP Addresses In our previous blog post, we covered domains and their various aspects. Now, let's dive deeper into DNS (Domain Name System) - the backbone of internet navigation. DNS, or Domain Name System, is essentially a translator for the internet. Its primary function is simple yet crucial: it converts human-friendly domain names (like example.com) into machine-readable IP addresses that computers use to identify each other. Without DNS, you'd need to memorize numeric IP addresses instead of easy-to-remember domain names. Before we explore how DNS works, let's clarify two important roles that make the domain system possible: A registry is an organization that manages a specific top-level domain (TLD) For example, Verisign manages the .com an…  ( 8 min )

    Bitcoin impulse move toward new highs sets a fire under HYPE, ETH, XMR and AAVE
    Key points: Bitcoin’s rally to $105,980 has traders predicting new all-time highs this week. Traders lift their end-of-year Bitcoin price targets to $200,000 based on technical factors and institutional investor adoption.  Bitcoin (BTC) has been stuck in a narrow range for the past few days, but the rally above $105,500 on May 18 increases the possibility of an upside breakout. Popular trader Alan said in a post on X that Bitcoin could soar to $116,000 early next week. Another bullish voice was that of Bitwise chief investment officer Matt Hougan. While speaking to Cointelegraph, Hougan said that a supply shock due to increased institutional demand could propel Bitcoin to $200,000 by the end of 2025. He expects seller exhaustion to occur at the $100,000 level. Crypto market data daily …
    Tornado Cash dev's attorneys say prosecutors hid exculpatory evidence
    Attorneys for Tornado Cash developer Roman Storm filed a motion asking the court to reconsider the motion to dismiss the case due to the prosecution withholding exculpatory evidence in the form of communications with the Financial Crimes Enforcement Network (FinCEN) dating back to 2023. According to a May 16 letter from Storm's attorneys to Judge Katherine Polk Failla, the FinCEN documents show that non-custodial crypto mixers do not fall under the legal definition of a "money transmitting business" and that prosecutors have known this since at least 2023. Despite having knowledge of the FinCEN guidance on crypto mixers, state prosecutors still proceeded with cases against the Samourai Wallet developers and Tornado Cash, the attorneys alleged. Letter sent by Roman Storm’s attorneys to Judg…
    Pavel Durov rejects EU pressure to censor Romanian election content
    Telegram founder Pavel Durov said he rejected pressure from a European Union (EU) country to censor political content on the social media platform ahead of the May 18 presidential elections in Romania. According to Durov, a Western European government, which he hinted at with a baguette emoji, approached the platform and requested it censor conservative voices, which he flatly denied. Durov wrote in a May 18 Telegram post: "You can't 'defend democracy' by destroying democracy. You can’t 'fight election interference' by interfering with elections. You either have freedom of speech and fair elections — or you don’t. And the Romanian people deserve both." The Telegram founder is an ardent defender of free speech, who is highly regarded in the crypto community for his stances on freedom of exp…
    Crypto execs beef up security following string of kidnappings: Report

Additionally, French law enforcement officials recently announced enhanced security measures for crypto entrepreneurs and investors, following at least three separate kidnapping incidents so far in 2025. The measures include security briefings and expedited access to police lines in the case of emergencies …

    Key points: Ether price rose 3% to $2,550 on May 18, triggering $22 million in short ETH liquidations. A bull flag on the chart suggests a $3,700 target, with analysts predicting Bitcoin’s price to go as high as $5,000 in May. Ether’s (ETH) price was up on May 18, rising more than 2.5% over the last 24 hours to trade at $2,536.

    Don’t believe the noise: There can never be too many L2s
    Opinion by: Igor Mandrigin, co-founder and CTPO of Gateway.fm Every couple of weeks, it seems another layer 2 rolls out, much to the chagrin of some Web3 industry commentators who are concerned about fragmentation. A recent Gemini Institutional Insights report actually noted how a new Ethereum L2 solution is launched approximately every 19 days. In response to the seemingly endless conveyor belt of new zkEVMs and optimistic rollups coming to market, the chorus of criticism continues to grow louder: “This is definitely the saturation point, no more chains are needed.” Some of the most outspoken critics of L2s argue that L2s are redundant, but this is narrow thinking. In many ways, the idea that creating new L2s should be slowed down is like arguing that there were too many websites in 1998.…
    BTC price to $116K next? Bitcoin trader sees 'early week' all-time high
    Key points: Bitcoin is convincing traders that an upside breakout is around the corner, with all-time highs in sight. One target demands $116,000 next week, moving BTC/USD firmly out of its narrow range. A quick dip before continuing higher is among the options for BTC price action into the new week. Bitcoin (BTC) reduced volatility to a minimum into the May 18 weekly close as traders bet on a fresh breakout. BTC/USD 4-hour chart. Source: Cointelegraph/TradingView BTC price brews classic breakout signal Data from Cointelegraph Markets Pro and TradingView showed the area around $103,000 acting as a BTC price magnet throughout the weekend. Now barely fluctuating up or down, BTC/USD was primed for a liquidity grab, with $105,000 and $103,000 both targets, data from monitoring resource Coi…
    ‘Bitcoin Standard’ author backs funding dev to make spamming Bitcoin costly
    Economist and author of The Bitcoin Standard, Saifedean Ammous, has weighed in on the ongoing debate over spam inscriptions on the Bitcoin network, suggesting he would “throw in a few sats” to fund a full-time developer focused on making Bitcoin spamming more difficult and expensive. Ammous made the remarks in response to a thread initiated by the pseudonymous developer GrassFedBitcoin, who called for Bitcoin Core to merge pull request #28408, which would enable node operators to filter inscriptions more easily. According to GrassFedBitcoin, the lack of inscription filtering tools contributes to unnecessary blockchain bloat and undermines Bitcoin (BTC)’s role as a monetary protocol. “No one running a node wants to relay inscriptions,” he wrote, arguing that the OP_RETURN limit increases we…
    Retired artist loses $2M in crypto to Coinbase impersonator
    Retired artist Ed Suman lost over $2 million in cryptocurrency earlier this year after falling victim to a scam involving someone posing as a Coinbase support representative. Suman, 67, spent nearly two decades as a fabricator in the art world, helping build high-profile works such as Jeff Koons’ Balloon Dog sculptures, according to a May 17 report by Bloomberg. After retiring, he turned to cryptocurrency investing, eventually accumulating 17.5 Bitcoin (BTC) and 225 Ether (ETH) — a portfolio that comprised most of his retirement savings. He stored the funds in a Trezor Model One, a hardware wallet commonly used by crypto holders to avoid the risks of exchange hacks. But in March, Suman received a text message appearing to be from Coinbase, warning him of unauthorized account access. After …
    UK to require crypto firms to report every customer transaction
    United Kingdom crypto companies will need to collect and report data from every customer trade and transfer beginning Jan. 1, 2026 as part of a broader effort to improve crypto tax reporting, the UK government said. Everything from the user’s full name, home address and tax identification number will need to be collected and reported for every transaction, including the cryptocurrency used and the amount moved, the UK Revenue and Customs department said in a May 14 statement. Details of companies, trusts and charities transacting on crypto platforms will also need to be reported. Failure to comply or inaccurate reporting may incur penalties of up to 300 British pounds ($398.4) per user. The UK Revenue and Customs department said it would inform companies on how to comply with the incoming …
    Hong Kong police busts $15M laundering ring that used crypto, 500 bank accounts
    Hong Kong police arrested 12 people involved in a cross-border money laundering scheme that relied on crypto and over 500 stooge bank accounts to launder HK$118 million ($15 million), local news outlets reported. The syndicate was dismantled on May 15, resulting in the arrest of nine men and three women in mainland China and Hong Kong. The suspects allegedly recruited others to open bank accounts to receive proceeds from fraud cases, which were then converted into crypto at crypto exchange shops to launder the illicit funds, Hong Kong Commercial Daily reported on May 17. The criminal organization rented a residential unit in the Hong Kong neighborhood of Mong Kok to plan and carry out its money laundering activities. Of the $15 million laundered, more than $1.2 million was linked to 58 re…

    Lambda in Python
    Buy Me a Coffee☕ *Memos: My post explains variable assignment. My post explains iterable unpacking in variable assignment. My post explains parameters and arguments. My post explains positional-only parameters in function. My post explains keyword-only parameters in function. My post explains positional-only parameters and keyword-only parameters together in function. Lambda: is the function which can be stored in a variable and parameter. is an expression. cannot be used with pass. is almost same as a normal function except these above. You can see Lambda Expressions You can use Lambda as shown below: # Equivalent v1 = lambda: 2 # def func(): return 2 v1 = lambda x: x # def func(x): return x v1 = lambda x, y: x+y # def func(x, y): return x+y v1 = lambda x, y=3: x+y # def func(x, y=3): return x+y v1 = lambda x=2, y=3: x+y # def func(x=2, y=3): return x+y v1 = lambda x=2, /, y=3, *, z=4: x+y+z # def func(x=2, /, y=3, *, z=4): # No error # return x+y+z v1 = v2 = lambda: 2 v1, v2 = [lambda: 2, lambda: 3] # No error v1 = lambda: pass v1 = def func() return 2 v1 = func() return 2 # SyntaxError: invalid syntax v1 = lambda: 2 print(v1()) # 2 v1 = lambda x: x print(v1(2)) # 2 print(v1(x=2)) # 2 v1 = lambda x, y: x+y print(v1(2, 3)) # 5 print(v1(2, y=3)) # 5 print(v1(x=2, y=3)) # 5 print(v1(y=3, x=2)) # 5 v1 = lambda x=2, y=3: x+y print(v1(6)) # 9 print(v1(x=6)) # 9 print(v1(y=5)) # 7 print(v1(6, 5)) # 11 print(v1(6, y=5)) # 11 print(v1(x=6, y=5)) # 11 print(v1(y=5, x=6)) # 11 v1 = lambda x=2, /, y=3, *, z=4: x+y+z print(v1(6, 5, z=4)) # 15 print(v1(6, y=5, z=4)) # 15 print(v1(6, z=4, y=5)) # 15 v1 = v2 = lambda: 2 print(v1(), v2()) # 2 2 v1, v2 = [lambda: 2, lambda: 3] print(v1(), v2()) # 2 3 def func(x=lambda: 2): print(x()) func() # 2 func(lambda: 4) # 4 func(x=lambda: 4) # 4  ( 4 min )

    The DNA of a Domain: Understanding DNS, FQDNs, and Domain Structures
    Domains are to the internet what names are to humans, making identification simple and intuitive for everyone. Just as we give people names instead of describing their physical characteristics each time we refer to them, domains give websites and online resources readable names instead of complex numerical addresses. When you type 'google.com' instead of having to remember a string of numbers like '172.217.168.238', you're benefiting from the domain name system that makes the internet accessible to everyone. One key difference from human names is that while many people can share the same name in the real world, a single domain can only point to one destination at a time on the internet. However, you can have multiple domains all pointing to the same resource, similar to having several nick…  ( 9 min )
    Amazon: From Online Bookstore to Tech Empire
    Chapter 1: The Birth of a Visionary (Pre-1994) The early 1990s were a time of tectonic shifts in both politics and technology. The Cold War had just ended, giving way to a wave of globalization. Meanwhile, the internet, once a military and academic curiosity, was on the verge of becoming commercially viable. In 1990, Tim Berners-Lee introduced the World Wide Web, and by 1993, web browsers like Mosaic were making the internet accessible to the average user. Amid this digital dawn, a Wall Street executive named Jeff Bezos was working at D.E. Shaw, a prestigious hedge fund. Bezos, a Princeton graduate with a background in computer science and electrical engineering, came across a stat that changed everything: internet usage was growing at 2,300% per year. Bezos immediately recognized the co…  ( 6 min )
    How I Improved My Coding Skills by Building Small Projects
    Hello Dev.to community! 👋 I’m excited to share my journey as a developer and how I managed to improve my coding skills significantly by focusing on building small practical projects. Here are some tips that worked for me: Start small: Don’t try to build complex apps from day one. Begin with simple projects like a to-do list or a calculator. Practice regularly: Dedicate at least 30 minutes every day to coding. Learn from mistakes: Don’t be afraid to break your code. Debugging is a great way to learn. Use online resources: Platforms like freeCodeCamp, MDN, and Stack Overflow are fantastic. Share your code: Use GitHub or Dev.to to share your projects. Getting feedback helps you improve. If you’re starting your coding journey or looking for motivation, keep pushing forward — consistency is key! Feel free to follow me for more coding tips and project ideas.

    Option Pattern in Go: Advanced Parameter Handling
    In Go, the Option pattern (also known as the configuration pattern or constructor pattern) is a commonly used design pattern, primarily for handling function parameters, especially when a function has many optional parameters. By using the Option pattern, we can pass and configure function parameters in a flexible and extensible way, avoiding the maintenance challenges and complexity of traditional methods with too many parameters. Let’s take a look at how the Option pattern is used in Go, analyze its implementation principles, and help you better understand how to apply this pattern in real-world projects. When constructing complex objects in Go, we often encounter the following pain points: // Example problem: Parameter explosion and difficult maintenance func NewServer(addr string, port…  ( 6 min )
    redictability, Pre-Recorded Reality, and AI Evolution: From Dilbert to LivinGrimoire
    Predictability, Pre-Recorded Reality, and AI Evolution: From Dilbert to LivinGrimoire Are We Just Predictable Scripts? The Dilbert Dilemma In an episode of Dilbert, the protagonist unwittingly has a conversation—not with his mother, but with a recording of her usual responses. She had pre-recorded their exchanges because Dilbert was so predictable, his side of the conversation could be anticipated without her present. Even when Dilbert realized he was talking to a recording, it kept responding accurately to him, as though their conversation were still fluid and natural. This presents a stunning thought experiment: how could Dilbert prove he was talking to a recording? What test could he run to confirm whether the responses were truly dynamic or just well-constructed predictions? …  ( 5 min )

    HTTP? 🤔 The Web's Unsung Hero Explained
    🌍 A Bit of History — Where HTTP Came From Back in 1989, Tim Berners-Lee invented the World Wide Web (WWW). But it wasn’t just websites — it was a system of protocols, and one of them was HTTP: the HyperText Transfer Protocol. HTTP was designed as a simple way to send hypertext (HTML) documents between computers. This allowed the user to experience a more dynamic and interactive way to access information. Since then, HTTP has evolved (currently at HTTP/3), but its core idea hasn’t changed: "Let the client ask, and let the server answer." That basic principle powers nearly every web app today. Without HTTP, the internet would not look, feel, or behave as it does. 📸 Request vs response: When your browser opens a website, it sends an HTTP request. The server replies with an HTTP respo…  ( 4 min )
    How to Fix LinkedIn Authentication in NextAuth.js: A Custom Provider Setup Guide

    Should you extend Supabase Auth with User Profiles?
    Supabase Auth already has an Auth Users table. The image might be blurry. If you visit the project in your Supabase Account, you can check your Auth table of the project. If you wanted to add additional data to your a User table, it's likely you've wondered 🤔 Should you create your own, separate profiles (or users) table in Supabase and link it with the Supabase Auth Users table? OR Should you extend the existing Supabase Auth Users table? Supabase’s recommended pattern is to create a separate profiles (or users) table in the public schema rather than altering the built-in auth.users table. The auth.users table (in the auth schema) is managed internally and isn’t exposed via the auto-generated API. Supabase maintainers explicitly advise “It is not recommended to modify the schema…  ( 4 min )
    supabase_vector_project container is not ready: unhealthy when using Rancher Desktop
    If you're using Rancher Desktop and ran into this error when running supabase start: supabase_vector_project container is not ready: unhealthy You're not alone — and here's what likely caused it (and how to fix it): Supabase CLI uses Docker under the hood, and it expects to communicate with the Docker Engine via a well-behaved socket or TCP endpoint. Rancher Desktop (especially with containerd or non-default networking setups) can cause issues with: Port forwarding DNS resolution Health checks (like with the vector container) This often results in the vector container going into an unhealthy state, crashing the entire setup. I recommend switching to Docker Desktop if you're planning to use Supabase CLI locally. On Docker Desktop: Supabase CLI is better supported and more stable If needed, enable: "Expose daemon on tcp://localhost:2375 without TLS" (from Docker Desktop settings → General) This change instantly fixed the issue for me. Hope this saves someone hours of debugging. Feel free to comment if you've found a better way!  ( 3 min )
    How Many AI Tokens to Play a Game of Chess?
    Just because AI tokens are cheap today doesn’t mean they’ll stay that way. When cloud adoption peaked around 2015, everyone migrated to “save money.” But many teams didn’t fully understand their on-prem costs, nor did they have a realistic plan for managing spend once they migrated. It’s as though we forgot about all our best practices. In 2015, cloud spend was projected to grow from $49B to $67B by 2018. In 2023? It hit $563.6 billion, with $678.8 billion forecasted for 2024 Alongside that growth came tool sprawl, security risk, and unexpected costs. Sound familiar? AI token usage is on a similar path only this time, the underlying mechanics are even more opaque. Let’s demystify it. A “token” is just a chunk of text (words, punctuation, etc.) that an AI model processes. But the cost and i…  ( 5 min )

    Comprehensive Guide to Pinia for State Management in Vue.js
    The first time I encountered state management in Vue, I was overwhelmed. I was building a simple dashboard application that had grown from a weekend project into something much more complex. Components were passing props six levels deep, and emitting events that would get lost in the hierarchy. I remember thinking, "There has to be a better way." That's when I discovered Vuex. It felt like finding an oasis in the desert. But as time passed and my projects grew more complex, I started to feel the pain points. The boilerplate code, the mutations that seemed redundant, the TypeScript support that always felt a bit bolted on rather than built-in. Then came Pinia, and it was like a breath of fresh air. In this article, I want to share my journey with Pinia, how it transformed my approach to sta…  ( 15 min )
    Yes the current job hunting landscape is a mess, here’s how you can play around it
    First let me say that the reason I’m writing this is because I’ve read many posts of people struggling with the current job market, and I feel you.

    Will AI replace human
    Will Ai replace programmers" by AI The idea that "AI will replace programmers" is a hot (and often exaggerated) debate. Here’s my take: AI Won’t Replace Programmers—But It Will Change the Job. -AI is a tool, not a replacement. Just like calculators didn’t replace mathematicians, AI (like GitHub Copilot, ChatGPT, or Devin) will automate parts of coding (boilerplate, debugging, docs) but can’t: 1 Understand complex business needs or ambiguous human requirements. 2 Design creative architectures or novel solutions. 3 Make ethical/critical decisions (e.g., privacy, security, trade-offs). Programming is more than writing code. It’s problem-solving, collaboration, and adapting to chaos—things AI struggles with. The “Junior Dev” Role Might Shrink AI can already: Generate simple code snippets. Fix common bugs. Answer Stack Overflow-style questions. Entry-level tasks may get automated, forcing new programmers to upskill faster (e.g., focus on system design, domain expertise). Future Programmers Will Look Different Shift from “writing code” to “orchestrating AI.” Example prompts: “Design a scalable API for X, optimize for cost, and explain trade-offs.” More emphasis on: Soft skills (stakeholder communication, UX empathy). Domain knowledge (healthcare, finance, etc.). AI-augmented workflows (prompt engineering, validation). Historical Parallels Fear: “High-level languages will kill coding!” → Instead, demand exploded. Fear: “No-code tools will replace devs!” → They just enabled non-devs. AI will likely create new roles we can’t yet imagine. Bottom Line Worst-case: Low-end coding jobs decline; programmers need to adapt. Best-case: AI removes grunt work, letting devs focus on harder, more meaningful problems. My advice: Learn to leverage AI, but double down on uniquely human skills (creativity, critical thinking, leadership). What’s your take? Excited or  ( 3 min )

    Enable or Disable console.log Globally in JavaScript Sometimes, during development or debugging, you need to quickly enable or disable logging globally across your entire JavaScript application. Here's a straightforward approach to achieve this. console.log Before we override the console.log function, it's crucial to keep a reference to the original function. let original_console_log = console.log; This ensures you can restore the original functionality anytime you want. Next, create a function that can toggle logging on and off by replacing console.log. let logging_enabled = true; function set_logging(enabled) { logging_enabled = enabled; console.log = enabled ? original_console_log : function () {}; } Here's what's happening: When enabled is true, console.log points back t…  ( 4 min )

    Advanced Use Cases for Proxy in Data Validation
    Advanced Use Cases for Proxy in Data Validation Introduction to Proxy Introduced in ECMAScript 2015 (ES6), the Proxy object allows you to create a wrapper for another object, enabling you to define custom behavior for fundamental operations (like property lookup, assignment, enumeration, function invocation, etc.). This allows for considerable flexibility in handling objects. As applications grow in complexity, the need for robust validation strategies becomes vital—especially when dealing with data from various sources such as APIs, user input, or databases. While Proxy is often showcased with simple examples of intercepting property access, its true potential lies in advanced use cases such as data validation. Prior to Proxy, JavaScript relied on direct methods (such as co…  ( 6 min )
    Small Language Models (SLMs)
    As we navigate through 2025, a significant paradigm shift is occurring in the AI landscape. While much attention has been focused on increasingly massive language models with hundreds of billions of parameters, a countercurrent has emerged: Small Language Models (SLMs). These lightweight yet powerful models are gaining tremendous traction among developers, enterprises, and researchers for their efficiency, practicality, and accessibility. SLMs, typically defined as models with fewer than 10 billion parameters (and often less than 1 billion), are proving that bigger isn't always better when it comes to solving real-world problems. Their rise represents a maturing of the AI field, moving from raw capability demonstrations toward optimized, targeted solutions. Small Language Models offer comp…  ( 7 min )

    Infraestrutura como Código não é uma escolha técnica. É uma questão de sobrevivência estratégica.
    Em um cenário onde a agilidade deixou de ser diferencial para se tornar pré-requisito, ainda existem empresas que tratam infraestrutura como um custo fixo, estático, centralizado — e, muitas vezes, emocionalmente preso à stack de um único fornecedor. Essa escolha, além de técnica, é cultural. E, quase sempre, onerosa. Infrastructure as Code (IaC) não é sobre versionar configurações. A pergunta não é mais “por que usar IaC?” Quantas decisões financeiras, técnicas e operacionais sua empresa está deixando de tomar por não conseguir abstrair a própria infraestrutura? Porque enquanto sua equipe debate qual cloud é "melhor", a concorrência já está rodando workloads em múltiplos provedores, otimizando custo e latência em tempo real. Uma infraestrutura agnóstica não é luxo. É alavanca. Funções específicas com melhor suporte em outro ambiente? Roda lá. Região mais próxima do usuário? Você escolhe. Não é a cloud que decide. Quem domina a infraestrutura como código, domina o custo, o risco e a mudança. O problema não é a nuvem. Sem IaC, sua empresa não tem flexibilidade. Otimização não é uma planilha. É arquitetura. IaC não é sobre “como rodar melhor”. A infraestrutura deixou de ser suporte. E quem ainda não entendeu isso, vai continuar pagando caro por aquilo que deveria estar controlando.  ( 4 min )

    System Design Basics: Why The Right Method Matters
    There are a lot of design patterns, techniques, and ideas around us—both online and offline. An architect can always look towards them for inspiration. But it is very important to ignore the noise. In this series of articles, we will follow the book Righting Software by Juval Löwy, which refers to the entire concept of project and system design as "The Method". We will also refer to this idea as The Method throughout the series. By system design, we mean the design of the architecture, not the detailed design—which deals with how classes, interfaces, and contracts should be built within a component. Detailed design can be discussed in another series. There is a common misconception that a good architect needs decades of experience building systems to know what the right design decisions ar…  ( 5 min )

    Why Software Architecture Matters in Real .NET Projects (Part 1)
    When you’re building an app in ASP.NET Core, it’s easy to fall into the trap of just writing code that “works.” Especially when deadlines are tight. But if you’ve ever looked back at your project and thought, “Ugh, this is a mess,” then you know why architecture matters. Think of software architecture like the blueprint for a house. You wouldn’t build a house without planning where the walls, plumbing, and electrical systems go — same goes for your code. Here’s a common scenario I see all the time: Code Rot — where the codebase gets harder and harder to work with over time. The God Controller [HttpPost] public async Task Create([FromBody] OrderDto dto) { var order = new Order { CustomerId = dto.CustomerId, Total = dto.Total, CreatedAt = DateTime.UtcNow }; _context.Orders.Add(order); await _context.SaveChangesAsync(); return Ok(order.Id); } Looks simple enough, right? But think about what happens when you need: Good architecture gives you practical benefits: Yes, .NET is powerful. Yes, EF Core makes it easy to get started quickly. But most tutorials and templates push you toward patterns like: In this series, we’ll walk through real architectural patterns used in modern .NET applications — not just theory, but examples you can actually use in your next project. • Part 2: Layered Architecture – Classic, simple, and still useful. You don’t have to be at a huge company or working on a massive enterprise system to care about architecture. Even a small app can benefit from a bit of structure. If you're tired of messy codebases, hard-to-test logic, or struggling to add features without breaking things, this series is for you. Stick around — we'll turn those spaghetti controllers and thin services into something maintainable, scalable, and enjoyable to work with.  ( 5 min )
    How I Use ChatGPT to Plan Features as a Frontend Developer (And Where It Falls Short)
    Originally published on Medium. Sharing what actually works (and what doesn’t) when using ChatGPT to plan real-world frontend features. When I start building a new feature, my biggest challenge isn’t the code — it’s deciding where to start. I used to open my editor with a vague idea like: “Build login page.” Ten minutes later, I’d have five tabs open, three half-written files, and no direction. Then I started using ChatGPT — not as a boss, but as a planning partner. Here’s how I use it to move faster without getting lost, and also where it sometimes fails. Instead of: “Build dashboard,” I ask: “Break down steps to build a responsive dashboard in Next.js.” It usually gives me: Set up layout Add sidebar, header Fetch data from backend Render UI components Handle empty/loading/error…  ( 4 min )

    Embeddings and Vector Search: How AI Understands Meaning Beyond Words
    If you’ve been exploring AI or machine learning lately, you might have come across the terms embeddings and vector search. At first, they sound a bit technical, but they’re actually super cool and powerful ideas that help machines understand meaning — not just keywords. Imagine you want a computer to understand words, images, or even sounds. But computers don’t really get language the way we do. So what do we do? We turn these things into numbers. More specifically, embeddings convert data — like a word or a picture — into a list of numbers called a vector. These vectors live in a kind of “number space,” where the position of each vector captures the meaning of the original thing. Because items with similar meaning end up as vectors close to each other in this space. For example, the words…  ( 4 min )

    Go router navigation observer
    go_router is one of the most popular package for managing navigation in a Flutter application, and since it became part of the Flutter team, it has become the main recommended solution. It's very easy to use, yet feature-rich. However, with the introduction of ShellRoute, observing the navigation flow in your app and having routes that are "aware" of navigation changes has become more difficult. As highlighted in this issue, when you add a ShellRoute, the app loses reactivity to route changes: the NavigationObserver is no longer triggered. While waiting for an official fix or built-in solution from the Flutter team, we can still implement route-aware behavior by listening to the GoRouterDelegate. The following code listens to the GoRouterDelegate throughout the widget's lifecycle and uses …  ( 4 min )

    Beyond LIKE: Mastering PostgreSQL's Built-in Full-Text Search
    A few months ago, my manager assigned me to a project that required improving its search functionality. The team initially considered Elasticsearch as the primary solution, though they were open to exploring alternatives. I researched the topic and discovered PostgreSQL's full-text search. Since our data was already stored in PostgreSQL, I compared the two tools. The application I worked on served private users and had strict privacy regulations, with complex conditions determining who could view or edit specific data within the company. These intricate queries proved challenging for Elasticsearch to handle effectively, while PostgreSQL's full-text search, being built on top of SQL syntax, required no extra work to handle this.

    Solving Software Problems with Common Sense: Lessons from Pólya
    Whether you’re debugging a stubborn production issue or architecting a scalable system, the nature of software development is deeply problem-solving at its core. Yet we rarely take a step back and ask: Are we solving problems effectively? Turns out, a Hungarian mathematician from the 20th century has some timeless advice for us. This post dives into some gold from George Pólya’s classic book, How to Solve It, and shows how its common-sense techniques originally meant for mathematics,are surprisingly useful for software engineers. Pólya's core idea is that general, common-sense questions help solve all kinds of problems,not just math ones. Consider these: What is the unknown? What are the data? What is the condition? These aren't math questions—they’re universal. They work whether you're …  ( 5 min )

All the logic is pre-applied to the variable content, our data, before it even arrives at the template engine. A typical example is Mustache. Logic-capable: The template engine allows you to define some logic in the template, such as not only what, but also when and how to display it. A typical example is Jinja2. Logic-full: Such template engines allow you to define any arbitrary logic in the template, by allowing you to even execute code in the …  ( 7 min )

Your fingers are flying across the keyboard, while you hold the entire system-its schema and the relationships between components-in your head. You’re not just writing variables and function calls. You’re creating interfaces, classes, structures. You’re building the system in real time-one large piece after another. You’ve caught the wave. 🌊 You’re deep, deep in the flow of creation. And then suddenly… you need to do something trivial-start a container, assign an IP address, add a service to systemctl. So you pause. Open a terminal. Try to recall the exact command. And Boom! - your flow is gone. Now you’re googling CLI flags,…  ( 6 min )

    Managing Supabase Auth State Across Server & Client Components in Next.js
    This article intends to save you 10+ hours of your valuable time, effort, and ‘developer’ pain, which I think is an entirely different kind of pain In your Next.js project, you'll need a way to keep UI elements like your Navbar (a Client component) in sync with Supabase Auth state You might be thinking - React Context to the rescue. But wait! Next.js Authentication Guide states: React context is not supported in Server Components, making them only applicable to Client Components. Your Navbar is a Client component, seems all good. But, Supabase Server-Side Auth recommends access to Auth User data, using only supabase.auth.getUser() in Server Components.

    I'm a self-taught dev from a small town in India. I need help getting a laptop/PC — can't afford one.
    I’ll keep this real — I’m a 21-year-old junior web developer from a small town in Gujarat, India. I never had the money to study Bachelor of IT or CS, so I taught myself how to code during my diploma in mechanical engineering. I have a huge passion for coding, After a few months of grinding through online tutorials, projects, and sleepless debugging nights, I landed my first dev job at a small service-based company. It doesn’t pay much (₹25k/month), but it was a start. I’ve been working on real projects using React, Next.js, etc., and learning more every day.

Built entirely with Tailwind CSS, this free eCommerce template is perfect for developers, indie makers, or startups who want to move fast without compromising design and usability.

    Dica de TI: Concatenação
    Dica de TI será uma série de posts com conteúdo sobre tecnologia. São posts curtos explicando alguns conceitos. Nos exemplos a linguagem usada será: Java Concatenar significa "colocar junto", “juntar-se”, “ligar-se” Para concatenar duas String, usa-se o método concat. Note que, já que o tamanho de uma String não pode mudar, a concatenação resulta na criação de um novo objeto. Também pode-se usar o operador + para a concatenação. Por exemplo, no trecho de código abaixo, a mesma linha é impressa duas vezes: String s1 = "Olá "; String s2 = "Mundo!"; System.out.println( s1.concat( s2 ) ); System.out.println( s1 + s2 ); As strings no java são imutáveis, ou seja, seu valor não muda A partir do java 15 tem um recurso chamado text blocks onde é possível formatar a string da forma como você quer que apareça, pode colocar parágrafo e espaço.

    An Introduction To App Development With Advanced Vibe Coding
    Written Date: 5/17/2025 For the last 2 years I've been using AI to drive most of my development efforts. It wasn't called "vibe coding" then, but it was just as frowned upon. The phrase "AI slop" was coined and tossed around willy nilly. Under every rock and around every corner you would find an expert ready to jump out and say that AI was overhyped. It was tenuous time to be using AI for helping you code. I will admit that the concerns brought forward were true then and are still mostly true now. However, there were these moments of brilliance that would shine through. These felt like samples of what was to come in the future, something that we would eventually consider to be just plain normal. I've held on to the inspiration and hope that came from those moments of clarity and brilliance…  ( 4 min )
    AI-Ready Congressional Data: Building a Python Tool for Plaintext Extraction
    Let's cut to the chase: Congressional Records are gold mines of political data, but they're trapped in PDFs and scattered across congress.gov. Yeah, there's an API, but it just gives you more PDFs or links to HTML pages. Not exactly AI-friendly. I needed plaintext, I needed it in bulk, and I needed it yesterday. So I built a Python tool that: Grabs data through the congress.gov API Ignores those pesky PDFs Extracts clean plaintext from the HTML pages Organizes everything neatly Why plaintext? Because you can actually do something with it! Search it, analyze it, feed it to AI models, cite specific sentences, or just read it without your eyes bleeding from PDF formatting. The tool leverages several key strategies to efficiently download records: The script uses the official congress.gov API,…  ( 6 min )
    Setup the easiest i18n system with NO KEYS
    Alright, let's cut to the chase. You're building a React MVP. You need to be fast, lean, and focused on validating your core idea. So why, oh why, are you already thinking about t('user.welcome.message.short')? Internationalization (i18n) is crucial for global reach, no doubt. But for an MVP, traditional i18n setup is often a premature optimisation, a time sink when you should be shipping and iterating. It means wrestling with JSON files, getting lost with keys everywhere in your app, and losing velocity at a time you shouldn't. i18n-keyless This is where the "keyless" philosophy, then first time embodied by i18n-keyless, becomes your MVP's best friend. The concept is refreshingly simple: Just write your UI text directly in your components, in your main language. That's it. import * as I…  ( 5 min )

    Stop Using :valid in Your Forms — Try This New CSS Feature Instead
    If you’re a web developer like me, you’ve probably styled a form before. And if you’re anything like me, you’ve tried to be helpful — maybe you added some color changes with input:valid or input:invalid, outlined fields, maybe even threw in a little transition effect. But then this came to your mind: Wait, why is this field showing up as valid before the user even typed anything? 🤦 Want smart web dev tips like this delivered straight to your inbox? join the newsletter and get your CSS selector cheat sheet for free You try to be nice to users. Give them visual cues. Maybe you change the border color on a valid input, or show a message when they make a mistake. You think you’re doing a good thing. But then someone opens your form and sees green borders before they’ve even clicked a thing. Valid already? They didn’t even type! It’s wrong. It feels broken. And worse: it actually is misleading. Let’s not even talk about accessibility. Using just colors for feedback? That’s a hard “no” if you care about users with color blindness. CSS pseudo-classes like :valid and :invalid don’t wait for the user to interact. If the input field meets the required rules on page load (or fails them), the styles apply instantly. That’s why your untouched email field might already look like a success story. Not cool. Say hello to :user-valid and :user-invalid. These two pseudo-classes work exactly how you always wanted :valid and :invalid to behave: *They wait for user interaction. Nothing changes until the user actually types, blurs, or otherwise engages with the input. Now that’s user-friendly feedback. If you’re still using :valid/:invalid on untouched fields, you're frustrating users. They’re seeing red borders before they’ve even typed anything. Or worse—green borders that falsely imply their input is good. By switching to :user-valid and :user-invalid, your forms become: ... Read the full article here  ( 4 min )
    DSA Chronicles Day 3: Solidifying the Core – 5 Problems, 5 Learnings
    Problem 1 Longest Substring Without Repeating Characters Problem: You must write an algorithm that runs in O(n) time. Link to problem: https://leetcode.com/problems/longest-consecutive-sequence/description/ Approach: First Thought: Used a basic count[256] array to track frequency of characters. Tried checking frequency and updating start directly if a duplicate was found. Misplaced order of start++ and count[s[start]]--, which caused logic errors for overlapping characters. Final Approach: Used Sliding Window technique with two pointers start and end. Maintained a count array to track how many times a character appeared in the current window. On detecting a duplicate character (count[s[end]] > 1), shrunk the window using a while loop. Then decreased count[s[start]] and moved start forwar…  ( 5 min )

    Single Responsibility Principle in Java
    Introduction The Single Responsibility Principle (SRP) is the “S” in the SOLID principles of object-oriented design. It’s often mentioned, sometimes misunderstood, and rarely applied correctly in large Java applications. Definition: A class should have only one reason to change. In practice, this means a class should encapsulate a single, well-defined responsibility — not “one method” or “one functionality,” but one axis of change. In this article, we'll go beyond trivial examples and explore real-world SRP violations, how to spot them, and how to refactor for maintainability and testability. Consider the following UserService class: public class UserService { public void register(String email, String password) { if (!email.contains("@")) { throw new IllegalArgum…  ( 5 min )
    Building Better Interfaces: My Journey from "Functional" to Polished UI in Java Swing
    By Alireza Minagar, MD, MBA, MS software engineer As a software engineer, I’ve spent most of my time making things work — efficient algorithms, robust logic, clean architecture. But recently, I gave equal attention to how software feels. Enter: SecureFleet, a desktop vehicle monitoring and management tool I’m building with Java Swing. At first, it was utilitarian — basic panels, a static table, and a couple of buttons. But I realized that professional software demands more than just working code — it deserves thoughtful, responsive, and intuitive interfaces. 🔨 What I’ve Implemented: A scrollable JTable with real-world vehicle tracking columns (Plate, Make, Model, Year, Owner, Status). A dedicated alert button (New Alert) highlighted in red for emphasis. A trio of functional buttons below: Track Vehicle, Add Entry, and Admin Panel. Clear color contrast and alignment for visual clarity. 🧠 What I Learned Along the Way: Grouping components into logical panels simplifies both alignment and code readability. GUI building tools (like NetBeans Designer) can help — but manual refinement makes the difference. 🌟 Why This Matters: 💡 What's Next: 🗣️ Let’s Talk: How do you balance aesthetics with functionality in desktop development?

    Speed vs Simplicity: Choosing the Right Cache
    Why I Switched from HashiCorp LRU to Ristretto for High-Performance Caching in Go While working on Buckt, I implemented a caching layer to speed up repeated file reads and downloads. I started with HashiCorp's lru, which was simple and easy to integrate. But as the system scaled and concurrency increased, it became clear that it couldn't keep up. This post highlights the issues I encountered and why Ristretto ended up being a much better fit. While the lru package is solid and predictable, I ran into a few limitations: Blocking Writes - All Add() operations lock the cache, leading to bottlenecks under concurrent load. Fixed Capacity, Not Cost-Based - It evicts based on item count, not memory usage — inefficient when storing large items like files. No Native Metrics - Hit/miss tracking mu…  ( 4 min )

    The Fourth Step into the World of RxJS: Unfinished Streams - Silent Killers of Applications
    Throughout the first, second, and third articles, we have embarked on a fascinating journey together: from our initial introduction to Observables, where we grasped the fundamentals of the reactive approach, through mastering operators that enabled us to efficiently transform and filter data, to combining streams, which unlocked the ability to synchronize data from multiple sources. We gradually transformed RxJS from an intriguing tool for experimentation into a powerful instrument for real-world tasks. Now, having taken three confident steps, it is time to confront the dark side of reactive programming. Like any technology, RxJS has its pitfalls. One of the most insidious is unclosed subscriptions, which can lead to severe issues such as memory leaks, performance degradation, and even app…  ( 10 min )

    Top Reasons to Outsource Image Annotation for Machine Learning
    In the fast-growing fields of machine learning (ML) and artificial intelligence (AI), image annotation is fundamental to developing reliable models. That’s where image annotation comes in—the process of labeling and highlighting objects, features, patterns, or any other elements of an image that may be useful for a machine learning program or model. However, performing image annotation in-house can also be time-consuming, resource-intensive, and expensive. This is one of the reasons why outsourced image annotation has become a popular approach. In this post, we’ll examine the challenges of standalone image annotation and the best reasons to outsource image annotation for machine learning. 1.

    Rethinking Control: The Evolving Human Role in a World of Smart Machines
    In this video (an excerpt of our next Frontiers of Software Engineering interview), Genaina Rodrigues discusses the critical and evolving role of humans in autonomous and robotic systems, emphasizing the distinction between "Human in the loop" (where humans are directly involved in decision-making and can intervene) and "Human on the loop" (where humans supervise or monitor the system). She argues that humans are an inevitable part of these processes, whether as active or passive stakeholders. She uses several examples to illustrate her points, including challenges in autonomous driving and autonomous avionics. A significant portion of her discussion focuses on the Boeing 737 MAX crashes. She explains that the accident wasn't just a system failure but involved a cascade of issues, includin…  ( 3 min )

    Why Queues Obliterate Lists in the Digital Battlefield
    Welcome, my fellow denizens of the cyber realm. If you've ever dared to manipulate a Python list like some medieval peasant, let me introduce you to a tool so blazingly efficient that it makes lists look like dial-up in a fiber-optic world: Queues. We’re running a little duel here—Python’s list.pop(0) versus deque.popleft(). The former? Laughable. It’s the floppy disk of data structures—archaic, slow, and embarrassing in modern computing. Meanwhile, deque? It’s the neural uplink to pure speed. Here’s the showdown: import timeit from collections import deque def list_pop(): lst = list(range(10**5)) while lst: lst.pop(0) def deque_popleft(): dqe = deque(range(10**5)) while dqe: dqe.popleft() if __name__ == '__main__': list_time = timeit.timeit(list_pop, number=1) deque_time = timeit.timeit(deque_popleft, number=1) print(f"List.pop(0) time: {list_time:.6f} seconds") print(f"Deque.popleft() time: {deque_time:.6f} seconds") Operation Execution Time List.pop(0) 1.218925 sec Deque.popleft() 0.006576 sec Read that again. Lists are basically waiting for the apocalypse while queues are flying first class to the future. The list operation is O(n)—which means each time you pop an element, the entire list gets shuffled like some analog relic. Deque, on the other hand, is O(1)—swift, seamless, untouchable. If you’re still using lists where queues would suffice, you’re practically inviting disaster. Imagine hacking the government’s mainframe with code so inefficient it takes a millennium to execute—no, thank you. Upgrade to deque, ascend beyond mortal constraints, and let your programs breathe the sweet air of efficiency. This has been Warlock's Data Structure Command Center—stay frosty out there.  ( 3 min )

    ⚡ Boost React Performance with Lazy Loading + Suspense
    ⚙️ Why Optimize React Apps? 🧠 The Problem In traditional React setups, all JavaScript code is bundled (using tools like Vite or Webpack) into a few files, often a single large main.js or bundle.js. On initial page load, the browser must download, parse, and execute this entire bundle before the application becomes interactive. Larger applications lead to larger bundles → slower Time-to-Interactive (TTI) and worse Largest Contentful Paint (LCP). Impact: Slower apps cause user frustration, higher bounce rates, and potentially worse SEO. Significantly reduce the initial JavaScript payload. Improve Time-to-Interactive (TTI), making the app usable faster. Enhance perceived performance and overall user experience, particularly on mobile and slow network connections. Reduce memory c…  ( 5 min )

    What’s Happening Inside Your Linux Kernel?
    Have you ever wondered how exactly your Linux system knows when a program is running, a file system is being mounted, or a new module is being loaded? It’s all happening deep inside the Linux kernel, and most of the time, we’re completely blind to it. But what if I told you there’s a way to peek inside, without rebooting the system, installing special software, or breaking anything? Welcome to the world of "kprobes", where you can trace important kernel events in real-time, like a system detective 🕵️‍♂️. Let’s dive in. Let’s say you’re running containers in production.

    Data transfer made easy - Rclone
    Let me get straight to it, I used to transfer data from Files.com or any other platform where files were dropped to our cloud buckets using scripts. It was all okay when the file sizes were within a few MBs, but things got painful once they grew into GBs. It started taking a lot more time. To speed things up, I tried running the transfer on a VM, it did get faster, but not faster faster, especially when the size crossed 400+ GB. That’s when I started looking for a better way to connect my GCP/AWS buckets directly with these storage platforms, something that could make the transfer process faster and more reliable. And that’s where rclone came into the picture. I have set it up on my vm as a job that runs the backups/transfer in ease sudo apt update curl https://rclone.org/install.sh | su…  ( 4 min )

    Instruction source location tracking in ArkScript
    Good error reporting is crucial in programming languages. Doing it at compile time was easy in ArkScript as we have all the context we need at hand, but since we compile code down to bytecode, which is then run by the virtual machine, we loose a lot of context: the source files, their path, their content, we don't have that anymore! Our runtime errors could only show the VM internal state. This article is about how it all changed. I went to the drawing board, and three solutions presented themselves to me: create a source location table in the bytecode, mapping an instruction to a file and line ; emit special instructions that would be skipped by the VM, and used only when the VM crashed, backtracking to find the nearest SOURCE instruction ; extend the size of instructions to 8 bytes and u…  ( 6 min )

    Show your portfolio using S3 and CodePipeline
    Successfully hosted a static portfolio using S3 + CodePipeline, documented the entire flow, fixed initial errors, and gained hands-on AWS experience. "Show your portfolio using S3 and CodePipeline." That's what the interviewer said. And guess what I did? I half-did it — only used S3, completely forgot about CodePipeline. Classic fresher moment. But I didn’t stop there. After some caffeine, chaos, and clicking around AWS documentation like a lost tourist, I figured it out! Hosted my portfolio on Amazon S3 deployment using AWS CodePipeline(if you change in index.html it will sudden showcase)--i think automated i don't know I’ve documented every step and every mistake (yes, including naming my bucket static-website-hosting-swiggy because... panic mode ). Lessons learned: Don’t rush. AWS has enough buttons to confuse the calmest soul. Automate with CodePipeline — it’s not just for big apps.

    What is Bitroot?
    What is a parallel public chain? The transaction execution of traditional smart contract platforms (such as Ethereum) is serial: one transaction can be executed only after the next one is executed, and even if the transactions do not affect each other, they cannot be processed in parallel. This leads to a very low throughput (TPS). Ethereum has an average of only a dozen TPS, and transaction congestion and gas fees soar during peak hours. Parallel public chains are different. They analyze the dependencies between each transaction and execute independent transactions on multiple computing cores at the same time. In layman’s terms, it is to make the blockchain multi-channel parallel operation like an assembly line, split the tasks into small pieces and process them in parallel, which can gre…  ( 6 min )

    Write Less, Reuse More: Template Inheritance in Flask Explained
    This turned out to be a pretty cool concept. While working on my site monitoring app, I had around three or four services like uptime checks, DNS lookups, pinging, and a few others. Since I’m not much of a UI designer, I ended up creating separate files for each service, even though they all shared the same layout. That’s when I discovered Flask’s template inheritance. Instead of repeating the same code over and over, you can create a base layout and reuse it wherever you want. It really helped clean things up and made everything way easier to manage. Here’s how you can set it up. template-inheritance home about contact Then, in your child template, you extend the base and override that block: {% extends "base.html" %} {% block content %} hello world!! {% endblock %} That way, you get the shared layout and can customize parts of the page without repeating your code.  ( 3 min )

    Understanding Generics in TypeScript: The Ultimate Guide to Reusable Code
    🚀 What Are Generics in TypeScript? When developing applications, we often need flexibility while maintaining type safety. TypeScript’s Generics solve this challenge by allowing us to create reusable components that can work with multiple data types. In this guide, we’ll break down generics step by step, ensuring you fully understand how to use them efficiently. Without generics, you would need separate functions for different data types. For example: function returnString(value: string): string { return value; } function returnNumber(value: number): number { return value; } This approach leads to redundant code. Generics solve this problem by creating a single function that works for all types. Generics use a placeholder type, such as , allowing a function to handle various dat…  ( 5 min )

    Article originally published here : https://alsohelp.com/blog/how-to-display-git-shortsha-in-terminal I had a problem displaying the image here on dev.to, everywhere else, the text is fine Article below : The answer is already given in this StackOverflow answer more than 6 years ago (!) and still holds true nowadays : git rev-parse --short HEAD # 4d7b213 In Git every commit is identified by a 40-character hexadecimal string named the "Git SHA". See the commit number pointer by the arrow ? (view it in original article) Yes, that's the git short SHA. Only the first 7 digits amongst the 40. The risk of collision is small enough to identify uniquely each commit. You can define an alias, on Linux or Windows, in order to display it without to remember the whole command : alias shortsha='git rev-parse --short HEAD' (exemple from my Linux machine) Will be used like this : shortsha # 4d7b213 Neat! Sometimes, you will try some attempt to display it somewhere in the footer, in order to increase confidence about which version of the website is deployed. I like and use it, but I admit it's not very common though. That was a quick recap about the git short SHA.  ( 3 min )

    How High-Performing Dev Teams Use Async Communication to Stay Productive
    Introduction In the fast-paced world of software development, every line of code counts—and so does every minute of your day. As tech teams increasingly embrace remote and hybrid models, we must clearly rethink how we communicate. Daily stand-ups, endless Zoom calls, and constant Slack notifications are no longer the productivity boosters they once seemed to be. Instead, high-performing developer teams use asynchronous (async) communication to stay aligned, reduce interruptions, and get more done. Daily stand-ups were designed to be quick, focused meetings to keep teams in sync. But in reality, they often: Happen at inconvenient times across time zones Turn into lengthy status updates Break developer flow and deep work Add unnecessary meeting fatigue According to a recent GitLab Remot…  ( 5 min )

    Scroll Animation Without JavaScript: Introducing animation-timeline: view();
    Adding scroll-based animations to your website used to mean reaching for JavaScript — from scroll event listeners to Intersection Observers or third-party libraries like ScrollMagic or GSAP. But what if you could get the same effect with just pure CSS? Meet the modern magic of CSS: animation-timeline: view(); With this property, you can create scroll-triggered animations without a single line of JavaScript. Smooth. Performant. Declarative. ⸻ 🧠 What Is animation-timeline: view();? The animation-timeline property allows CSS animations to be driven by something other than time. When you use the special value view(), the animation is controlled by the element’s scroll position in the viewport. That means your animation will start and progress based on how far the user has scrolled…  ( 4 min )

    Fixing the "Connection failed" Error in Cursor
    If you’re using Cursor and keep seeing this error: “Connection failed. If the problem persists, please check your internet connection or VPN” You’re not alone. This issue tends to appear randomly—even when your internet is working just fine. It can interrupt your flow and make the experience frustratingly unstable. Cursor uses the HTTP/2 protocol to power many of its AI features, since it allows streaming responses. However, not all networks handle HTTP/2 properly. If you're on a corporate network, using a VPN, or behind a proxy like Zscaler, HTTP/2 connections might fail. As a result, Cursor may struggle to index your code or connect to its AI backend—leading to that annoying “Connection failed” message. Thankfully, there’s a simple workaround. Cursor now includes a fallback to HTTP/1.1, which is slower but much more reliable on certain networks. Here’s how to enable it: Open Cursor Settings (Cmd or Ctrl + ,) Go to VS Code Settings Search for http2 Find and check the option “Disable HTTP/2” This forces Cursor to use HTTP/1.1 instead, which should fix the connection issue and restore access to AI features. ✅ Once you do this, the error should stop showing up and things will run more smoothly.

    Understanding SSD Endurance: What Does TBW Really Mean?
    If you're using an SSD — and let’s be honest, you probably are — you might have come across a spec labeled TBW, or Terabytes Written. But what does it actually mean for the real-world lifespan of your drive? Let’s break it down in simple terms. TBW stands for Terabytes Written, and it’s a metric that tells you how much data can be written to an SSD before the drive is likely to start wearing out. Think of it like a fuel limit — not for how long the drive will exist, but for how much write work it can handle over its lifetime. For example, if your SSD has a TBW of 600, that means you can write 600 terabytes of data to it before you start entering the "wear-out" zone, as defined by the manufacturer. Let’s do a quick, real-world calculation. Say you're a regular user writing about 100 GB per day — downloading files, installing apps, updating your system, working on projects. That’s quite a bit for a typical user, but let’s go with it. 100 GB/day = 36.5 TB/year 600 TBW / 36.5 TB/year ≈ 16 years Yes, sixteen years of daily 100GB writing. That’s how much endurance a 600TBW SSD gives you. And if you write less than that (which most people do), it’ll last even longer. You can monitor your SSD’s health and total data written using tools like: CrystalDiskInfo (Windows) smartctl from smartmontools (Linux/macOS) These tools can show you how much data has been written so far, so you can get a real-time sense of your drive’s life expectancy. TBW is an important but often misunderstood metric. SSDs don’t just suddenly die after hitting the limit, but the risk of data loss increases as the flash memory wears out. That said, for most users — even power users — modern SSDs offer years of reliable performance. So the next time you see a TBW rating, don’t panic. Unless you're stress-testing your drive daily, you're probably fine for a decade or more.  ( 3 min )
    Optimizing Mental Math: Fast Multiplications and Divisions for Software Engineers

Right now I want to talk about Upgrading. I know it is scary to upgrade something that will break horribly if it goes wrong. It's likely user facing. It may be hard to test outside production. This project sits underneath a large portion of the authorization systems on the internet. According to GitHub's project tracking, which I believe only reports on public projects, 100,000+ projects, and 500+ packages depend on this project. That is a lot of things to upgrade.

    🚀 Seamless Data Magic: From Notion to Database with MCP Server & AI Agents
    🎯 The Goal Build a seamless bridge between non-engineering contributors managing data in Notion and engineers who need that data formatted for database insertion. Values like "Japan" or "Tokyo" don't match the foreign keys in different tables. Notion: Used as the collaborative data entry platform for non-engineers. MCP Server: Bridges Notion and external tools, enabling structured data retrieval via API. Cursor Agent: An AI-powered agent that automates data transformation, semantic inference, and prompt execution. TypeScript: Ensures type safety and robust data handling throughout the automation scripts. 🚀 Let's ask Cursor Agent to infer the semantic data to be the foreign keys in one prompt! Non-engineers created and updated event entries directly in Notion—no devs required. To extra…  ( 5 min )
    Building beyond the ISO 32000 PDF standard
    The Portable Document Format (PDF), formalized as ISO 32000, has been the global workhorse for digital documents since the 1990s. It was a revolutionary answer to the chaos of inconsistent document rendering across platforms, ensuring that every reader would see the same layout, regardless of software or hardware. From government agencies and hospitals to enterprise back offices and freelance contracts, PDF has become a trusted container of visual fidelity and permanence. But here’s the challenge: the modern digital world doesn’t run on permanence alone. It runs on interactivity, data-driven workflows, responsive design, and seamless integration. The needs of today’s businesses and developers are no longer just about how a document looks—but how it behaves, how it connects, and how fast it…  ( 7 min )
    Did AI just kill 6,000 tech jobs?
    I got this letter from Mosh Hamedani and I just wanted to share it here in case anyone hasn't read it yet. You’ve probably seen the news: Microsoft just laid off 6,000 people. And right away, the internet did what it always does: freaked out. “AI is replacing developers!” But let’s slow down for a second. First off, Big tech layoffs aren’t new. In fact, they’ve been happening for years, long before anyone was worried about ChatGPT. Here are a few examples from the past: 2014: Microsoft laid off 18,000 people after acquiring Nokia 2015: HP cut 30,000 jobs during restructuring 2016: Intel laid off 12,000 employees to shift toward data centers IBM, Yahoo, and others have done the same, multiple times These things happen, not because developers are being replaced by AI, but because companies s…  ( 3 min )

    How AI and Python Helped Modernize a Legacy Insurance System
    Modernizing a legacy platform is never easy – especially in industries like insurance, where decades-old systems and processes are deeply ingrained. In this post, I’ll share how our development team tackled a real-world challenge at an insurance company by injecting some AI, APIs, and Python-powered automation into a claims handling workflow. We’ll walk through the problem we faced, our solution architecture, some code snippets illustrating key pieces (yes, actual Python code!), and the lessons we learned along the way. By the end, you’ll see how even a monolithic legacy system can be augmented with modern tech – and hopefully be inspired to try something similar in your own projects. The Legacy Challenge Our starting point was a painfully manual claims process. When customers submitted …  ( 11 min )

    Formal Verification and Why I Fell in Love With It
    I’m currently in my final year as a student, and I recently found myself drawn into something I never expected to enjoy: formal verification. I want to share a little story about how I got here, what I’ve been learning, and why I believe formal verification might be one of the most exciting and valuable skills in the world of smart contracts and blockchain. At first, formal methods felt intimidating. I come from a non-mathematical background, and the idea of writing "proofs" with symbols and logic felt way out of my league. But I was curious. I started asking myself: how do we really know a smart contract does exactly what it’s supposed to do? This question led me to the world of formal verification. a field where we use math and logic to prove that a piece of code behaves correctly in all…  ( 3 min )

    The Public internet is a bottleneck for blockchain — DoubleZero CEO
    Public internet infrastructure is the critical speed and performance constraint on high-throughput blockchain networks, according to Austin Federa, co-founder and CEO of DoubleZero, a project developing high-speed fiber optic communication rails for blockchains. "The downside of the public internet is it was never built for high-performance systems. It was always built for this sort of relationship of one big server talking to one little server," Federa told Cointelegraph in an interview at Consensus 2025. The executive explained: "We have validators all around the world. Rotating leader schedules all the time. And then they switch from having to be massive consumers of data to extremely massive broadcasters of data. So that means that they need huge amounts of resources both on ingress an…
    Moody's downgrades US credit rating due to rising debt
    Moody's credit rating agency downgraded the credit rating of the United States government from Aaa to Aa1, citing the rising national debt as the primary driver behind the reduction in creditworthiness. According to the May 16 announcement from the rating agency, US lawmakers have failed to stem annual deficits or reduce spending over the years, leading to a growing national debt. The rating agency wrote: "We do not believe that material multi-year reductions in mandatory spending and deficits will result from the current fiscal proposals under consideration. Over the next decade, we expect larger deficits as entitlement spending rises while government revenue remains broadly flat." The credit downgrade is only one degree out of the 21-notch rating scale used by the company to assess the c…

    A Bitcoiner’s guide to South Africa’s Garden Route
    South Africa’s Garden Route, famed for its lush forests, expansive beaches and charming towns, has become a testbed for Bitcoin adoption. From Mossel Bay to Witsand and Plettenberg Bay to Knysna, Bitcoin has become popular among shop owners and travelers alike for a multitude of reasons. “We’re seeing the early signs of a parallel, permissionless economy emerging across an entire region,” James Caw, founder of SimplB — a local crypto asset provider — told Cointelegraph, “where small businesses benefit from faster, lower-cost digital payments and where people have more options to earn, send and receive sound money securely.” For tourists, the benefits are immediate: no currency exchange hassles, no international card fees, and the ability to pay instantly and securely. For locals, Bitcoin (…
    The DeFi mullet — Fintech needs DeFi in the back
    Opinion by: Merlin Egalite, co-founder at Morpho Labs Fintechs in the front, decentralized finance (DeFi) in the back: the DeFi Mullet. Today’s fintech companies offer excellent user experiences but are constrained by traditional financial infrastructure — siloed, slow, expensive and inflexible. Meanwhile, DeFi provides lightning-fast, cost-effective, interoperable infrastructure but lacks mainstream accessibility. The solution? Combine fintech’s distribution and user experience with DeFi’s efficient back end. The mullet is inevitable Fintech companies heavily rely on traditional financial (TradFi) infrastructure that is siloed, slow to deploy and run, and costly to maintain. This inefficiency limits their control over costs and product offerings and has potential infrastructure risks. Fin…
    Bitcoin to $250K in 2025 ‘totally possible’ — crypto analyst Scott Melker
    Bitcoin’s next explosive move could send the asset to $250,000 by the end of 2025, according to Scott Melker, a crypto analyst and host of The Wolf of All Streets podcast. Speaking in a recent interview, Melker cited growing institutional interest and diminishing volatility as key factors that could drive the next leg up. “250K this year, totally possible,” Melker said, adding that Bitcoin (BTC)’s volatility has declined significantly in recent years. “It used to be about three times as volatile as the S&P. Now it’s less than two times.” He pointed to increased involvement from pension funds and ETF issuers as evidence of a more mature, stable market. The shift, he argued, reflects a broader trend of institutional adoption. “The more institutional money, the more Wall Street money, the mor…
    Everstake defends non-custodial staking as SEC weighs industry input
    The US Securities and Exchange Commission (SEC) has held discussions with Everstake, one of the largest non-custodial staking providers globally, to explore clearer regulatory definitions around staking in blockchain networks. The meeting, which also involved the SEC’s Crypto Task Force, comes at a time when over $193 billion in digital assets are staked across major proof-of-stake (PoS) networks. However, despite the massive scale of participation, staking remains in a legal gray zone in the US as regulators wrestle with its classification under existing securities law. The previous SEC administration also took enforcement actions against major players such as Kraken, Coinbase, and Consensys due to their staking services. The agency, under pro-crypto President Donald Trump, has recently d…
    New Zealand man arrested in $265M crypto scam tied to FBI probe
    A man from Wellington, the capital city of New Zealand, has been arrested in connection with an FBI-led investigation into a global cryptocurrency fraud operation that allegedly stole $450 million New Zealand dollars ($265 million). According to New Zealand Police, the man is one of 13 individuals charged after authorities executed search warrants across Auckland, Wellington, and California over the past three days. The charges stem from allegations that members of an organized criminal group manipulated seven victims to obtain large amounts of cryptocurrency, which was then laundered through multiple platforms between March and August 2024. The US Department of Justice has indicted the man under federal law, including charges of racketeering, conspiracy to commit wire fraud, and conspirac…
    Panama City mayor teases Bitcoin reserve after meeting El Salvador's Bitcoin leaders
    Panama City Mayor Mayer Mizrachi has hinted at establishing a city-level Bitcoin reserve in a cryptic post following his meeting with two of El Salvador’s Bitcoin policy leaders. “Bitcoin Reserve,” Mizrachi wrote to X on May 16 after meeting El Salvador-based Bitcoiners Max Keiser and Stacy Herbert. While Mizrachi didn’t share details about his discussions with Keiser and Herbert, the timing of the post came 11 days before the Bitcoin 2025 conference in Las Vegas, where Mizrachi is scheduled to speak.

    Paraguay deports three undocumented immigrants after crypto mining theft attempt
    Paraguayan law enforcement has deported three individuals and arrested another for attempting to steal crypto miners at a facility near the country’s Itaipu hydroelectric dam. According to a May 15 statement from Paraguayan prosecutor Irene Rolón, the men were caught by police soon after breaking into a locked section of Teratech SA’s facility in Coronel Bogado, leading to their arrest. Prosecutors believe the men may have had ties to Teratech as independent contractors, but are still waiting on official confirmation from the company’s CEO. The three deported were Chinese nationals Jinping Duan, Tian Jianyun and Zheng Guanglong, who did not have official entry records into the country. Paraguayan authorities and Interpol believe the men illegally entered through Brazil or Bolivia. The thre…
    Bitcoin bull flag and standard profit taking hint at eventual rally to new BTC price highs
    Key takeaways: Traders expect a Bitcoin price pullback to $90,000, but a bull flag could break out to new highs if profit taking near the range highs reduces. On-chain data suggests the current profit taking is too weak to extinguish Bitcoin’s current price momentum. Bitcoin (BTC) price has spent the bulk of the week pinned below $104,000 to $105,000, which many analysts have labelled as a resistance zone, but an alternative view suggests that BTC is simply consolidating within a bull flag. A bull flag is a continuation pattern that is characterized by a period of sideways price action following a sharp uptrend, and when the structure confirms or breaks from the trendline resistance, the uptrend continues.  BTC/USDT 1-day chart.

    French crypto entrepreneurs to receive extra security amid recent kidnappings: Report
    Crypto entrepreneurs and their families in France will receive enhanced security measures amid a recent rise in crypto-related kidnappings in the country, Politico reported. According to the May 16 report, the measures include priority access to police emergency lines, home security assessments, and safety briefings from French law enforcement to ensure best practices are being followed. France’s Interior Minister Bruno Retailleau introduced the security measures as part of a broader effort to counter the recent wave of attacks. "These repeated kidnappings of professionals in the crypto sector will be fought with specific tools, both immediate and short-term, to prevent, dissuade and hinder in order to protect the industry.” Law enforcement officers will also undergo "anti-crypto asset lau…

    The Importance of Real-World Experience for Engineering Students
    Engineering is more than formulas, projects, or classroom lectures. While academic learning builds a foundation, real-world experience shapes your mindset, communication, and decision-making abilities. From my own journey, I’ve seen how industrial training, leadership roles, and volunteering helped me grow far beyond the textbook. When you work in a real production environment, like a garment factory, you begin to understand how things actually work on the floor. Industrial training teaches you about time management, coordination, and how teams solve problems in real-time. You observe how small improvements in workflow or communication can bring large results. This kind of learning is something no classroom can fully teach. Leadership roles in university also help in developing essential soft skills. Organizing events, managing volunteers, and communicating under pressure make you more confident and responsible. It teaches you how to plan, lead, and adapt — which are valuable qualities in both academic and professional life. Volunteering adds another layer to your development. It allows you to give back to your community while also learning empathy, teamwork, and people skills. Volunteering shows that you are proactive and socially responsible, which employers and organizations appreciate. These experiences make your resume stronger, but more importantly, they shape your personality. They prepare you for interviews, teamwork, and real challenges in your career. You learn how to think practically, solve problems, and communicate your ideas clearly — all of which are essential in today’s job market. If you are an engineering student, try to step outside your comfort zone. Look for internships, attend workshops, join a leadership program, or take part in a volunteering activity. The real world is the best teacher, and the lessons you learn there will stay with you forever. Start early, stay curious, and take every opportunity to grow.  ( 3 min )
    make vs new in Go: Differences and Best Practices
    Go language provides two commonly used ways to allocate memory: make and new. Although both are used for memory allocation, their roles and usage scenarios are quite different. Understanding the differences between these two is crucial for writing efficient and maintainable Go code. This article will thoroughly analyze the differences between make and new, their suitable scenarios, and offer some usage tips. make and new new: Creates Zero Value of Pointer Types new is a keyword in Go used for memory allocation. Its function is to allocate a block of memory for a type and return a pointer to that memory. The memory allocated by new is initialized to the zero value of the type.

    Testing Strategies for CI/CD: Balancing Speed, Depth, and Sanity 🧪
    Hey there, fellow developer! 👋 Let’s talk about something we all say we love but secretly dread: testing. You know the drill—you push code, cross your fingers, and pray the CI/CD pipeline doesn’t light up like a Christmas tree. But what if I told you testing doesn’t have to feel like a chore? In this guide, we’ll break down the three pillars of CI/CD testing—unit tests, E2E tests, and code coverage—and share practical strategies to make your pipelines faster, safer, and actually enjoyable. Let’s dive in! 1. Unit Tests: The First Line of Defense What they do: Test individual functions, classes, or modules in isolation. Why they matter: Catch bugs early, like checking each ingredient before baking a cake. Best Practices: Mock dependencies (databases, APIs) to keep tests fast an…  ( 4 min )
    Why we built Springtail: Scaling out Postgres shouldn’t mean starting over
    We didn’t set out to build a typical database. We built something that works with the Postgres you already use, scales when you need it, and doesn’t require throwing everything out just to keep growing. This is a golden age for databases. There’s distributed systems, cloud-native options, fully managed services, and battle-tested engines like Postgres that keep getting better every year. But despite all that progress, scaling your database is still surprisingly hard. Many teams still build applications with a single-node Postgres backend. It’s how a ton of apps start, and how they stay for as long as possible. And for good reason. Postgres is rock solid, well-loved, and everywhere. It’s mature, feature-rich, and backed by an incredibly active community. But fast forward a bit, and that sin…  ( 4 min )

    8 important security changes from Android 8 to Android 15
    Yesterday, when I was at the bakery buying some snacks, I overheard a conversation between one attendant with another regarding her Android phone not downloading and installing the ChatGPT app. Curious about the subject, I decided to ask her more regarding her issue, and to talk about it. She explained her smartphone was an older model, using Android 8.0, aka Oreo, and that's probably why the chatgpt android app wasn't downloading and installing on it. We talked a while, and I pondered that while there are a lot of reasons for an app not to work on an older Android OS version, the most relevant of them are the security reasons. So I decided to list eight changes from Android 8.0 (Oreo) to Android 15 (Vanilla Ice Cream), the most impactful and relevant of each major version: Project Treble …  ( 10 min )

    Real-World Asset Tokenization: Introduction
    Hello, everybody! At Info-Polus, we see the opportunities RWA tokenization presents. Today, let's dive into it! The crypto bull market is not only driving up the large, established cryptocurrencies such as Bitcoin and Ethereum. Memecoins such as Dogecoin (DOGE), Pepe, and Shiba Inu, which have a lower market capitalization and are particularly volatile, have recently attracted great attention with impressive price rallies. By contrast, the increases in real world assets (RWA) have attracted less public attention - although many experts believe this crypto segment has excellent prospects… So what lies in RWA? As the name itself suggests, Real World Assets represent tangible and other assets existing in the “real world” (real estate, exchange-traded commodities, art objects) tokenized for use in the DeFi segment. The growing interest in tokenizing real-world assets stems from the promise of greater transparency, security, and global market reach. Let the numbers speak for themselves: the DeFi industry has boomed over the past few years, peaking at $181.22 billion in total value locked (TVL) on December 2, 2021. According to DefiLlama, RWA is steadily carving out its space in this ecosystem, with a TVL exceeding $8 billion in January 2025. Interested in what the future of RWA holds for us?

    What I Learned from Lean Manufacturing Training!
    During my industrial training, I had the opportunity to explore Lean Manufacturing, a system designed to make production more efficient by eliminating waste and focusing on value creation. I learned about important tools like 5S, which stands for Sort, Set in order, Shine, Standardize, and Sustain. This method helps keep workspaces clean and organized, which is essential for safety and productivity. Another key concept I studied was Kaizen, which means continuous improvement. It emphasizes that small daily changes can lead to significant improvements over time. I also gained practical experience with Just-in-Time inventory management, which ensures materials arrive exactly when needed, reducing storage costs and avoiding overproduction. This training helped me connect the theoretical concepts learned in class with real-world production challenges. I realized that efficiency is not only about speed but also about smart use of resources and people. I saw how teamwork and communication play a vital role on the factory floor. Lean Manufacturing is not just a set of techniques; it is a culture of continuous problem solving and improvement. As an Industrial and Production Engineering graduate, I believe this mindset will guide me in all my future professional endeavors.  ( 3 min )

    Python Variables Explained for Beginners
    Hey folks, welcome! Welcome to the first article in my new series: Why Python? Unlike C, Python is widely used—and one big reason is libraries. Python comes with many built-in libraries, and you can import even more depending on what you need. Think of a library as a toolkit that helps you do things faster and easier. A Real-Life Example: Randomness Let’s say I’m playing a card game with friends. I never know which card I’ll get next—why? Because it’s shuffled. It’s random! In Python, we can use something similar: import random as rand Just like shuffling cards gives you unpredictable results, the random library in Python helps you generate random numbers or make random choices. In real life, randomness is unpredictable. Cool, right? That’s the magic of Python! Introduction to Variables Now let’s talk about variables. Imagine a kitchen shelf with jars: In programming, think of those jars as variables. Each jar (or variable) stores something inside it—just like a variable stores data. Syntax Example: Let’s say we name our jars like this in Python: jar1 = "Sugar" Now, if we want to see what’s inside, we can do: Easy, right? That’s a wrap! In the next article, we’ll look at types of variables and best practices for naming them. Happy coding!

We’ll create a dynamic component that animates a parabola (y = ax² + bx + c) and allows the user to update coefficients in real time. The component will: Render points on a canvas dynamically using useRef. React to prop changes via useEffect. Maintain performance using stable references and controlled rendering. Hook/API Purpose useRef Access raw DOM nodes (canvas) use…  ( 4 min )
    2901. Longest Unequal Adjacent Groups Subsequence II
    2901. Longest Unequal Adjacent Groups Subsequence II Difficulty: Medium Topics: Array, String, Dynamic Programming You are given a string array words, and an array groups, both arrays having length n. The hamming distance between two strings of equal length is the number of positions at which the corresponding characters are different. You need to select the longest subsequence1 from an array of indices [0, 1, ..., n - 1], such that for the subsequence denoted as [i0, i1, ..., ik-1] having length k, the following holds: For adjacent indices in the subsequence, their corresponding groups are unequal, i.e., groups[ij] != groups[ij+1], for each j where 0 < j + 1 < k. words[ij] and words[ij+1] are equal in length, and the hamming distance between them is 1, where 0 < j + 1 < k, for all indices…  ( 26 min )
    Old Fashioned CSS Formatter – A Modern Successor to CSSComb
    It’s been a long time coming, but I’m thrilled to finally share a new developer tool that emerged from my constant need for better CSS property organisation: Old Fashioned CSS Formatter — a professional-grade Visual Studio Code extension designed to fill a very real and long-standing gap in modern front-end development. If you’ve ever used CSSComb in the past, you know how much it helped maintain order in stylesheets. However, a vacuum was left with the project, which is no longer maintained, and this new tool steps in. When CSSComb stopped receiving updates, it left a hole for many developers, including me. It had a simple job: sorting CSS properties meaningfully. But it did it well. With tools like Stylelint and Prettier becoming more prevalent, it seemed like no one focused anymore on …  ( 4 min )

    Inductive Types in TypeScript
    This post demonstrates a TypeScript pattern I've been experimenting with for the last year or so. I've been calling this pattern "inductive type constraints", but perhaps a better name would be "smart constructors", since they have "correct by construction" semantics (here's a nice article about them). "Smart constructors" definitely sounds cooler, but "inductive types" are what they're called in other typed languages, so I went with that. Before we dig into how they work, here are a few examples of how they can be used to solve a few long-standing TypeScript issues: Exact "exact types" is the 2nd-most popular feature request of all time Exact ensures that a type does not have any extra properties (Playground) Json One of the oldest TypeScript issues (#187) (Playground) In the TypeSc…  ( 4 min )
    How to Transform Jupyter Notebook into a Maintainable AI Project
    A Python package named modinit that facilitates the rapid scaffolding of AI model training repositories with a standardized, best-practice structure. This tool is designed to save time and ensure consistency across machine learning projects. In machine learning and AI development, it's common to begin with Jupyter notebooks for experimentation and prototyping. However, as projects mature, there's a need to transition this code into a more structured, maintainable, and deployable format. This transition poses several challenges: Code Organization: Notebooks often contain a mix of data processing, model definition, training loops, and evaluation code, making it hard to modularize and reuse components.

    Hero Sections: A small visual study
    A 'Hero' is a large banner at the top of a website's home page. As it is the first thing a visitor sees when they enter a website, it's the one chance to make a first impression. This can be an image or a video. For our purposes, we'll only need an image. This image should be high-quality and meaningful. A purely decorative image won't do. It should convey the proposition of a fall festival in some capacity. The image shouldn't be too busy either. Negative space is necessary, as the purpose of the central graphic is to complement the other components of the section, not override them. The text block is where you capture interest. It consists of one or both of two parts: The headline delivers the core message in just a few words. Luckily, we already have a very fitting tagline: "Real Farm…  ( 4 min )

    “Calculus, Code, and the Quiet Art of Understanding Change”
    Calculus is often taught as a tool for solving problems, such as rates of change, areas under curves, and optimization. But what if it’s also a lens to understand how the world quietly evolves? In coding, every function, loop, and variable tells a story about change—about moving from one state to another, sometimes subtly, sometimes dramatically. The derivative isn’t just a slope; it’s a whisper about the next moment. The integral isn’t just an area; it’s the sum of all moments passed. As a developer and math lover, I find myself drawn to these silent narratives, where math and code meet philosophy. In this space, I’ll explore those intersections: How math powers AI models How quantum ideas challenge our intuitions How elegant code can be more than just efficient — it can be poetic. If you love thinking deeply about the things most take for granted, welcome aboard. Let’s decode change together!!  ( 3 min )

Understanding the "Unreliable" Transport Protocol If you’re just starting to learn about computer networks, you might find the term "UDP" a little confusing, especially when people describe it as "unreliable." Don’t worry, In this post, we’ll break things down simply so you can understand what’s happening behind the scenes when a message is sent using UDP. Think of a UDP packet like a shipping box. It contains two things: A very small label (header) – just 8 bytes long The actual content (data) – what you want to send The label has the following four items: Source Port (16 bits): Like the return address, it tells the receiver where the message came from. Destination Port (16 bits): Tells where the message should go - kind of like a delivery address. Len…  ( 5 min )

    Data related Non-Functional Requirements
    Brief reminder: Functional requirements = what the system should do Non-functional requirements = how the system should behave Usually applications handle complex datasets and need to: Store data efficiently in databases Cache expensive operation results Provide search and filtering capabilities Process messages asynchronously and more. Suppose you have a banking website. Would you rather show wrong numbers to your customers or show no data at all? Rather show no data. However, if you're Facebook, you would of course rather show wrong data (not-updated likes count for example) than no data. So non-functional requirements matter.

    Node.js Event Loop Visualized Series
    Have you ever wondered how Node.js handles asynchronous operations so efficiently? The secret lies in the Event Loop, a core component that orchestrates the execution of tasks. In this series, "Node.js Event Loop Visualized," we will dive deep into the inner workings of the Event Loop using a powerful tool: the Event Loop Visualizer. The Event Loop Visualizer is a tool I've been developing, based on a fork of an existing project. It offers a unique insight into the real execution of the Event Loop by utilizing a modified version of the Node.js core. Unlike other tutorials, courses, and posts that often rely on simulations to explain the Event Loop, this tool captures the actual execution, recording each phase in real-time. This provides a clearer and more accurate understanding of how Node.js manages tasks and events. Feel free to explore the Event Loop Visualizer and see it in action for yourself! The Event Loop Visualizer is composed of several key sections: Code Editor: Write and execute JavaScript code to see how it interacts with the Event Loop. Macrotask and Microtask Queues: Visualize how tasks are queued and processed. Call Stack: Observe the current call stack and how functions are executed. Event Loop Phases: Track the different phases of the Event Loop, such as Timers, Poll, and Check. Ticks & Rejections Loop Phases: Understand how Node.js handles next ticks and microtasks. Metrics: Monitor loop counts and event processing statistics. Simulated Terminal: View real-time output from your code execution. In each post of this series, we will analyze a specific block of code and explore how it is executed within the Event Loop. We'll cover a range of examples, from basic like timers to more advanced such as handling sockets and streams. Stay tuned as we embark on this journey to demystify the Node.js Event Loop. Whether you're a seasoned developer or just starting, this series will provide valuable insights and practical knowledge. Let's get started!  ( 3 min )

    Tim Sweeney says Apple has ‘neither accepted nor rejected’ second Fortnite submission to the App Store
    Epic CEO Tim Sweeney says Apple is flat-out ghosting Fortnite’s latest App Store submission—“neither accepted nor rejected” it—putting this Friday’s big update at risk. Epic filed a new build on May 14 after Apple ignored their May 9 resubmission, even though Apple usually reviews 90% of apps within a day. A 2021 court injunction told Apple to “quit it” and follow the rules, but didn’t actually force Fortnite back on the store, so Apple’s free to leave the game hanging. Meanwhile, Sweeney’s been all over X pointing out Fortnite knock-offs that Apple approved (and some it quietly yanked), stoking fan outrage and shine a spotlight on the limbo. With zero word from Apple and a crucial update looming, iOS Fortnite players are left staring at a loading screen—and nobody knows what Epic will do next.  ( 3 min )

    Samsung shows off OLED trch for Mixed Reality HMDs at 5,000 Pixels per inch
    TL;DR: Samsung demoed a tiny 1.4-inch RGB OLED-on-Silicon panel packing a whopping 5,000 ppi—outclassing Apple’s Vision Pro (3,386 ppi) and Meta Quest 3—at SID Display Week. The microdisplay can hit 15,000 nits brightness at 120 Hz with 99% color gamut, effectively banishing the “screen door” pixel grid in VR. Beyond VR headsets, Samsung cranked a lower-density demo (4,200 ppi) to over 20,000 nits and notes the same tech could slot into a smartwatch. By building OLEDs onto silicon wafers, it uses chip-fab tricks to cram in ultra-tiny, super-bright pixels for next-gen wearables.  ( 3 min )

    Max Mode in Cursor: Power, Access, and Missing Controls
    Max Mode in Cursor caught my attention because of how easy it is to enable—and how quietly it can start racking up costs. There’s no prompt, no permission gate, and no usage alert. It made me wonder: in an enterprise setup, how would we even know if someone turned it on? Cursor recently rolled out Max Mode, giving users access to their most powerful models—like GPT-4o and Claude Opus—with massively expanded context and smarter completions. It’s a great feature. But if you’re managing Cursor on an enterprise account, there’s a pretty big catch: anyone can turn it on, and it immediately starts billing your account. Here’s what Max Mode is, how it works, and why I think the lack of admin controls is a risky move. TL;DR: Max Mode in Cursor gives users powerful models with expanded context—but …  ( 6 min )

    Building MCP Server for Kubernetes
    Intro Built my first MCP Server for read only Kubernetes operations. This MCP server was created to provide a secure way to interact with Kubernetes clusters without allowing any create, update, or delete operations. It only exposes read-only APIs to ensure your clusters remain safe while still enabling AI assistants to help you monitor and troubleshoot your Kubernetes resources. Model Context Protocol (MCP) has been very popular lately and you can see the huge adoption as every company is releasing their official MCP server. MCP server is the new API endpoint. Kubernetes is equally popular and there are many Kubernetes MCP servers out there.

    “It’s clear you are better than the reviewer” - said a Senior Software Engineer
    I got selected to move forward for a Software Engineer (Frontend) role with a foreign company from a cold DM and was given a test assignment. I delivered beyond the expected result, only to receive feedback from a review that seemed out of touch with current web development best practices, especially within the Vue 3 and Nuxt 3 ecosystem. A senior engineer who looked over my work remarked, “It’s clear you are better than the reviewer,” which inspired me to share this story. The review listed several shortcomings: No Composition API usage. No project architecture. Code repetitiveness. No cards stored in localStorage. Not following the Figma design. Bugs. Many of these points were vague or incorrect. Let’s examine each claim. Reviewer’s Claim: “No composition (Vue 3)” Reality: Every componen…  ( 5 min )
    YAML Tutorial: A Beginner's Guide to Writing YAML Files
    Hey Guys! This blog will make you understand what YAML is all about. Initially it was called Yet Another Markup Language, but later renamed to YAML Ain't Markup Language (a recursive acronym). YAML is the cleanest way to write configuration files. I'm guessing you already know we need config files for certain tasks while developing apps or working that DevOps magic. There are multiple ways to write configuration files such as XML, JSON, and TOML (plus several others), but YAML has some distinct advantages. These file formats make developers happy and help our data dance from server to server or client to server. They're primarily used for transmitting data between servers and clients, particularly in web applications. These are basic data formats for writing important stuff like secret fil…  ( 7 min )
    Finding Pair with Target Sum
    Given a sorted array of numbers and a target sum, find the pair of numbers that add up to the target sum. Example: Input: [1, 2, 3, 4, 5, 6], Target: 10 Expected Output: [4, 6] (since 4 + 6 = 10) Let's explore two approaches to solve this problem: the straightforward brute force method and the more elegant two-pointer technique. The brute force approach is the most intuitive way to solve this problem. We'll check every possible pair of numbers in the array and see if they add up to the target sum. Use two nested loops to consider every possible pair For each pair, check if their sum equals the target Return the pair when found function findPairBruteForce(arr, targetSum) { for (let i = 0; i < arr.length; i++) { for (let j = i + 1; j < arr.length; j++) { if (arr[i] + arr[j] === …  ( 6 min )

I have been working on it for a few years and I think it's time to publish it for others to benefit from it. Since from the invention of the Internet, more and more software are moved to the online world as services, and the developers are moved to work in the DevOps mode. Besides the coding environments, they inevitably need to work with shells and command line tools as part of their daily work, from coding work, to service deployment, live site investigation and mitigation, etc. Depends on which operating systems they are using, they may need to interact with different types of command-line shells, such as PowerShell on Windows, GNU bash on Linux, an…  ( 6 min )

    Custom Elements: The Superpower of Svelte 5
    Svelte 5 and the Future of Truly Reusable Web Components In today's web development ecosystem, framework fragmentation can be a headache. Can you imagine creating components that work equally well in React, Vue, Angular, or even plain HTML? With Svelte 5 and Web Components technology, this isn't just possible—it's surprisingly simple. Modern frontend development is based on reusable components. However, these components often remain "trapped" within the ecosystem for which they were created. A button made in React will hardly work in a Vue application without significant modifications.

In a production environment where uptime, reliability, and speed matter, you need something better. That’s where CI/CD comes in. Continuous Integration and Continuous Deployment (CI/CD) introduces automation and structure to your development workflow. With it, every change pushed to your repository can be automatically tested, built, and deployed—without manual steps. This reduces errors, accelerates delivery, and ensures your team spends less time deploying and more time building. In this guide, we’ll walk through setting up a CI/CD pipeline for a Python backend application using GitHub Actions a…  ( 11 min )
    Diary of an Elm Developer - Lazy L-System generation
    L-System Studio is an environment for creating and exploring L-Systems. It was built with Elm by Hunor Geréd. I learnt about the project when he decided to submit it to Built with Elm back in April 2023. It's a fun application for exploring L-Systems but it can be quite resource intensive. My browser has even crashed on several occasions. Definitely not a good look for Elm. Could the performance be improved whilst using Elm or do we have to resort to mutable generation in JavaScript? That was the nagging question. The first thing that caught my attention was the huge number of SVG nodes that were being generated in the DOM. Those SVG nodes are created by looping over the array of characters returned by LSys.generateSequence. It's not one to one but the number of SVG nodes that are added to…  ( 9 min )
    CloudWatch Alarm Integration with KMS-Encrypted SNS Topic
    Configure an Amazon CloudWatch alarm with an encrypted Amazon Simple Notification Service (Amazon SNS) topic. Monitoring and alerting are essential in the cloud but securing those alerts is important too. In this post, we are going to explore how to configure a CloudWatch Alarm so that you are being notified through an SNS topic, which is encrypted with KMS, so your alert data stays secured. Note: You must use an AWS Key Management Service (AWS KMS) customer managed key to deliver Amazon SNS notifications with an encrypted Amazon SNS topic for a CloudWatch alarm. If you use the default alias/aws/sns AWS managed key for encryption, then the CloudWatch alarm fails to initiate the alarm action. You then receive a message that's similar to the following in the Alarm History section: "Failed …  ( 5 min )
    What’s The State of WASI?
    By: Matt Butcher The WebAssembly System Interface (WASI) specification is a proposed standard that describes how to connect a WebAssembly application to its underlying environment. Designed with security at the fore, WASI describes mechanisms for Wasm applications to interact with system resources such as clocks, sockets, filesystems, environment variables, and other Wasm components. The original WebAssembly project was jointly created by Mozilla, Google, Microsoft, and Apple in order to provide a common language runtime inside of the web browser. Following the path of web standards like HTML and CSS, the early Wasm creators decided to standardize the technology through the W3C. Nearly a decade later, the W3C standardization of WebAssembly is moving along well. WebAssembly 1.0 was complete…  ( 6 min )

    Query MongoDB Like a Human with ScoutDB
    🗥️ So I was casually doomscrolling X (yes, again)... when I stumbled upon a post by DEV Community that made my brain short-circuit: ✨ “ScoutDB turns plain English into MongoDB queries.” Wait, what?! You've got the data questions, but not always the query-fu: "Find all users who joined after Jan 2023 and liked more than 5 posts" Normally, you'd need to hand-craft some MongoDB incantation like: db.users.aggregate([ { $match: { joinDate: { $gte: ISODate("2023-01-01") }, likes: { $gt: 5 } } } ]) But what if you could skip the syntax pain? ScoutDB is like having a friendly AI that: ✅ Understands what you're trying to ask in English explore like a boss You type: Show me all posts with more than 100 likes created in the last 30 days ScoutDB replies with: db.posts.find({ likes: { $gt: 100 }, createdAt: { $gte: new Date(Date.now() - 30*24*60*60*1000) } }) Then maps the results and relationships for you in a visual explorer. No more $lookup headaches. No more crying in JSON. Saw this post by @thepracticaldev on X 👇 (I swear MongoDB and ScoutDB logos look like they just agreed to rescue all devs from query hell) 🗣️ English → MongoDB query? ✅ 🧠 Auto-maps your schema? ✅ 🎨 Visual canvas for data exploration? ✅ 🧣 Found it while doomscrolling Twitter?

    Why Developers Keep Confusing Sprint Goals with Status Updates, and Why Sprint Goals Are Important.
    Ever been in a daily Scrum where developers list empty words like “I coded the UI”? That’s a status update, not a sprint goal discussion. I’ve seen this confusion tank team focus for many years - and yes, I fix it every time. Sprint goals are Scrum’s core, yet developers often treat them as empty to-do lists. So let’s explore why developers confuse them with status updates, why sprint goals matter and how to fix the status update confusion to deliver real value. Why the confusion? A sprint goal is a clear outcome, like “Our team will allow users to enable gravitational anti-matter this sprint so that users can fly above water in their cars” or “We need to reduce technical debt to free up 25% of EC2 resources for other higher value added batches.” It’s the common why for the whole team t…  ( 5 min )

    What is Nginx ?
    How NGINX Works Web Server Acting as a Reverse Proxy: The Middleman with Superpowers Here's how it works: A client sends an HTTP request to your web application. NGINX receives the request first, acting as the front-facing gateway. Based on its configuration, NGINX forwards the request to the appropriate backend server. The backend server processes the request (e.g., querying a database or rendering a web page) and sends the response back to NGINX. NGINX then returns the response to the original client. Key Advantages of Using NGINX as a Reverse Proxy: Load Balancing: Distributes traffic across multiple backend servers using strategies such as round-robin, least connections, or IP hash.

    Mastering Media Queries in CSS – A Beginner’s Guide
    Introduction What is a Media Query? A media query is a CSS technique used to apply styles based on the device's characteristics, like screen width, height, orientation, or resolution. It helps make websites responsive. Syntax of a Media Query @media only screen and (max-width: 600px) { @media is the rule. only screen targets screen devices. (max-width: 600px) means it will apply when the screen is 600px or less. Inside the curly braces, you write the CSS rules that should apply. Common Media Query Breakpoints /* Small devices (phones) */ @media (max-width: 600px) { ... } /* Tablets */ @media (min-width: 601px) and (max-width: 992px) { ... } /* Laptops */ @media (min-width: 993px) and (max-width: 1200px) { ... } /* Desktops */ @media (min-width: 1201px) { ... } These are just examples. You can set custom breakpoints based on your design needs. Why Media Queries Matter Improves user experience across different devices Helps build mobile-friendly websites Allows you to customize layouts for different screen sizes My Practice Example /* Default style */ /* For mobile screens */ @media (max-width: 600px) { This changes the paragraph text size and color on smaller screens. Final Thoughts Learning media queries has helped me understand how to build responsive designs. It’s a simple but powerful tool in CSS that every web developer should master.  ( 3 min )
    C# Concurrency in a nutshell
    In this article, I will briefly discuss the most important aspects of concurrency in C#. A system is said to be concurrent if it can support two or more actions in progress at the same time. A system is said to be parallel if it can support two or more actions executing simultaneously. — The Art of Concurrency book To make breakfast, one person can boil eggs, make tea, and toast bread at the same time. However, they cannot drive to the grocery store and come back simultaneously. To make breakfast and buy groceries in parallel, you need at least two people. A computer with a single CPU and a single thread can perform multiple tasks by quickly switching between them. However, to work on multiple jobs simultaneously, multiple threads are required. Each thread acts as a separate worker, allowi…  ( 6 min )
    How Core Java Helped Me Understand the MERN Stack Better
    Introduction When I first started my journey as a MERN stack developer, I saw JavaScript and its ecosystem as a whole new world — dynamic, event-driven, and surprisingly flexible.

    Optimizing scopes data in ArkScript VM
    If you don't know me yet, I have been working on ArkScript for nearly 6 years now. ArkScript is a scripting language in modern C++, running on a custom virtual machine (like Python or Lua), with the goal of having a syntax easy to learn and use, a C++ interface to embed it in programs, and decent performances (without trying to be as fast as Lua though, Mike Pall is a genius and did outstanding work on LuaJIT). A silly question that you shouldn't care about, unless the perceived slowness of the language is becoming a problem. Recently, I added more benchmarks to the language, and I was quite astonished to see that it was 1.5 times slower than Python on such a simple benchmark: (mut collection []) (mut i 0) (while (< i 1000000) { (append! collection i) (set i (+ i 1)) }) (mut sum 0) (s…  ( 10 min )

    Programming language of the future Part 5: Data and Ownership
    A large part of state management is data management - who owns data? How are limits kept track of? How is data allocated and destroyed? Our system has objects transparently migrating from server to server, so pointers are not an option - we have references instead. References can become invalid if the referenced object is destroyed, which leaves us with two options. Guarantee at the compiler and runtime level that all references remain valid while used, through lifetime tracking and the borrow checker, or force the programmer to handle the case of an invalid reference on every access. The latter is easier, if we introduce "owning references", which there can be only one of, and that are always valid. In fact, when an object is just declared as a field of another object - that's an owned re…  ( 5 min )

    How The JavaScript Event Loop Handles Asynchronous Code Execution
    Ever wondered how JavaScript can fetch data from an API, wait for a timeout, and respond to user clicks, all without freezing your browser? It's not magic, it's the event loop. Even though JavaScript runs on a single thread, it handles multiple operations seamlessly using a clever system of background tasks, queues, and scheduling. Before we dive into how the event loop keeps things running smoothly, let’s break down the key components that make JavaScript’s async behaviour possible. Call Stack: Web APIs / Node APIs: These are provided by the browser or Node.js, things like setTimeout, fetch, DOM events, etc. They run asynchronously outside the main thread. Task Queue: After a Web API finishes (like a setTimeout), it sends the callback to the Task Queue. Microtask Queue: For things like Pr…  ( 4 min )

I’m a pretty heavy YouTube consumer – it’s where I get news, learn stuff, find entertainment, the whole nine yards. And lately, watching hours of content, I’ve started to notice something… a kind of invisible wall that seems to go up around certain creators. You know how it is. You find a creator you vibe with. Their takes are fresh, or funny, or they just explain things in a way that clicks. So you subscribe, hit the bell, all that. And then you scroll down to the comments.

Each web browser has its own JavaScript engine that interprets and executes JavaScript code, converting it into machine language to run on the computer's hardware.This javascript engine plays a pivotal role in providing …  ( 6 min )
    Protect Your Web App in 2025: 7 OAuth & JWT Hacks You Wish You Knew Yesterday
    Web apps are under siege in 2025. Cybercriminals are more sophisticated, APIs are under constant attack, and traditional authentication methods like session cookies or static API keys just don’t cut it anymore. According to Verizon’s 2023 Data Breach Investigations Report, 74% of breaches involved the human element—including social engineering, errors, and misuse of credentials. That means the majority of attacks could have been mitigated with stronger access controls and token-based authentication.

    Goodbye Sails.js — Thanks for the Ride
    In 2025, we finally made the call — Sails.js is out of our stack. We tried hard to keep Sails alive. We added TypeScript, wrote custom types, wrapped controllers, hacked the models, and even considered forking it to modernize the whole thing. But the deeper we went, the more obvious it became — the foundation just isn't made for today. Outdated patterns, broken dependencies, Docker images with critical vulnerabilities... The project is barely maintained — just version bumps for security. It’s no longer a tool for modern development. Our main project today is RestoApp — an open-source platform for restaurants, food delivery, and retail. A big part of it is the admin panel. Originally, we started from sails-hook-adminpanel by Kostya Zolotaryov — and we’re genuinely thankful to him for that. It gave us a solid starting point. Over 8 years, we evolved it a lot — changed frontend stacks multiple times — and today, it’s become a fully independent, configurable, and open-source admin system. No longer tied to Sails, no specific ORM, no locked-in logic. Just a single config file — and it works. Meet Adminizer 📌 What’s next? So yeah — this is our goodbye to Sails. Now — we move forward.  ( 3 min )

    Django Proxy Models: The Secret Weapon for Cleaner, Simpler Code
    We store data to record the state: A password change, an order made, an order delivered and etc. Such things can be seen as stand-alone events or, in many cases, they are part of a step in a process. And, it's common to see those things be chucked into a single table. All those columns can result in models that bloat to 1000s of lines. When looking at a model like that, you may have an urge to group all columns and methods to make sense of what is going on. It's tiring enough doing it once, but it becomes a bigger issue when you and others have to go through the same process each time. In situations like this, proxy models can become invaluable! They can enable you to split columns in models into targeted sections. In this article, I will: Share the basics of what proxy models are Why sho…  ( 5 min )
    With SPL, It Seems We Don’t Need ORM Anymore
    ORM technology indeed simplifies basic CRUD operations, but it also has many limitations when dealing with complex calculations. Hibernate’s HQL is notably inadequate, making it difficult to implement dynamic column calculations and multi-layer associations. While JOOQ improves flexibility through its DSL, its grouping calculations require multi-layer nesting, leading to more verbose code than native SQL. esProc SPL is like a “plug-in” for data computation! To write a multi-layer JOIN based on dynamic conditions, you had to use chain calls in Java for half an hour with JOOQ. Now you can implement this in just a few lines of SPL script, and its syntax is more intuitive than SQL. For example, calculating ‘top 3 sales by department’, which even requires nesting in SQL: SELECT dept, name FROM …  ( 5 min )

Microsoft Dynamics 365, with its suite of powerful ERP and CRM tools, is one of the leading platforms helping organizations streamline operations, gain visibility, and make data-driven decisions. But here’s a truth many companies overlook: the success of a Dynamics 365 project doesn’t just depend on the software itself; it depends heavily on the implementation partner you choose. Let’s be honest. Implementing a system like Dynamics 365 is no small task. It involves change management, deep process understanding, data migration, user training, and long-term support. Without the right guidance, even the best technology can fail to deliver results. This is where a specialize…  ( 5 min )
    The Psychology of Brand Loyalty: What Makes Customers Stick?
    Brand loyalty is a powerful and vital force in the consumer marketplace, influencing both business strategies and customer behaviors. It refers to a consumer’s deep, enduring preference for a particular brand, often leading to repeat purchases and positive word-of-mouth. Understanding the psychology behind brand loyalty goes beyond just recognizing habitual buying; it involves delving into the emotional, cognitive, and social factors that make customers stick to a brand over time. For businesses, brand loyalty is not only a reflection of consumer satisfaction but a critical element for long-term success. Companies that successfully tap into the psychological triggers of loyalty enjoy increased customer retention, higher lifetime value, and a competitive advantage in their industries. Th…  ( 9 min )
    We Don’t Need More Apps -We Need Better Ones
    Let’s cut the crap. In 2025, the app stores are drowning in clones, crypto wallets with 2 screens, habit trackers built in 4 hours, and yet another to-do list app that looks like it was spat out of a UI template generator. We’re not short on apps. We’re short on quality. On soul. On effing intention. Yeah, I said it. We’re shipping MVPs without asking: Who is this for? Why does this matter? Would I even use this more than once? Half the time, apps today feel like the digital equivalent of a sticky note: quick, forgettable, and destined for the trash. You’ve got a killer stack. You’re running Next.js, Firebase, Tailwind, Gemini APIs, and some fancy prompt-chaining wizardry. Just because you can ship it in 2 days doesn’t mean you should. Real talk: The app store doesn’t need another crypto portfolio tracker. No one is asking for your AI-based meditation timer with 17 onboarding screens. We do not need another damn social app that starts with “Hey! What’s your vibe today?” We need apps that solve real pain. That stick. That respects users' time. Want to Stand Out? Do This Instead. Focus on flow, not just features. Ask real users what sucks in their life-solve that. UX is king. API is queen. AI is the court jester- use it wisely. Don’t chase hype. Chase use. Tools That Help You Build Better nativebridge.io - a platform that lets you preview, test, and iterate your mobile apps instantly. Stop shipping apps just to fill your portfolio.

    Locking Down the Box: A Comprehensive Guide to Container Security Evaluation and Hardening
    Containers are the backbone of modern cloud-native applications, but their security can’t be an afterthought. This article dives into the critical importance of container security evaluation, actionable steps to assess risks, strategies to minimize vulnerabilities, and best practices to build hardened, trustworthy container images.   Why Container Security Evaluation Matters   Containers encapsulate applications and their dependencies, offering portability and scalability. However, their ephemeral nature and reliance on shared resources introduce risks. A single vulnerable container can compromise an entire cluster, leading to data breaches, service disruptions, or compliance violations. Attackers often exploit misconfigured images, outdated software, or excessive privileges. Evaluating …  ( 5 min )
    Real-Time Threat Modeling with AI? This Open-Source WAF Does It.
    Cyberattacks are becoming a daily occurrence—is your web app still running unprotected? Traditional WAFs (Web Application Firewalls) rely on outdated signature libraries that are slow to update and often miss the mark, acting like Schrödinger’s cat of false positives and missed threats. That’s where SafeLine WAF steps in. Backed by semantic analysis + AI, it rewrites the rules of defense: detecting threats via behavior modeling instead of static patterns, catching malicious activity at the API level before it reaches your app. Open-sourced by Chaitin Tech, SafeLine is fast becoming a trendsetter in next-gen WAFs on GitHub. While researching WAF products, I found SafeLine to be incredibly powerful and beginner-friendly. Here’s a hands-on walkthrough. The latest release of SafeLine focuses …  ( 4 min )

    Why AI Workflows Are the Future of Business Automation
    Automation Isn’t Enough Anymore For decades, business automation has been a reliable tool for improving efficiency, moving emails, copying data, and sending alerts. But today’s business environment is faster, more data-driven, and increasingly unpredictable. Traditional rule-based automation is struggling to keep up. Traditional automation tools like Zapier, Make, and basic RPA (Robotic Process Automation) platforms helped companies automate repetitive tasks. These systems operate on "if-this-then-that" logic. However, they have significant limitations: Lack of Adaptability: Even small deviations, like a changed email format, can cause failures.

    How I’m Earning $3,000 at 14 While Learning to Build SaaS Products
    Hi! I’m Kostiantyn, a 14-year-old fullstack developer with solid skills in JavaScript and TypeScript. Over the last few months, I’ve earned more than $3,000 working on real projects and freelancing — all before even finishing high school. Mastering JavaScript/TypeScript and Next.js for fast, scalable frontend and backend development. Building simple SaaS projects that solve real problems and bring real income. Learning backend basics with Node.js and NestJS, since this stack is in huge demand. Why I Put Go on Hold I started learning Go because it’s popular for backend and microservices. But quickly realized it doesn’t fit my current goals. Go requires more time to master and lacks the quick feedback loop I get with JavaScript and Node.js. For now, I prioritize skills and tools that help me earn money faster and build complete products. To keep building SaaS products and freelance projects that improve my skills and generate income. Practical experience and fast results are key at my age. I’ll continue focusing on JavaScript, Next.js, and NestJS, then later consider other backend languages like Go or Rust when I’m ready for bigger challenges. Thanks for reading!

    A Look Back at an 8-Year-Old 2D Tank Game
    A Nostalgic Story About 8 years ago, when I was just a kid, I began my coding journey with a school book — you know, the classic QBASIC chapter. I learned about variables, conditional statements, and control flow, writing small programs like basic calculators and whatnot. But then, there was this one section at the end... That single section changed everything. I learned how to draw rectangles, circles, and all kinds of shapes on the screen. And then my brain started buzzing with ideas. You know what’s coming next… my very first game. If you’re a tech person, you’re probably thinking: “Who the hell makes games in QBASIC?” 😅 Well… an innocent 11-year-old me did.

    HTML for Beginners: Your First Step into Web Development
    Description: Learn the basics of key HTML tags and how to build your very first simple webpage with easy-to-follow code examples. Introduction Figure: A historical newspaper front page (Hilo Tribune). HTML stands for HyperText Markup Language, and it’s the foundation of every web page. It uses code (tags inside ) to tell your browser how to display content. This is similar to how a newspaper uses headlines and sections to organize information. For example, the image above shows a newspaper with a big headline and columns of text. In HTML, we create structure with heading tags ( through ) and paragraph tags ( ), just like the title and stories in a newspaper. Why HTML Matters When a browser loads a website, it reads the HTML file to decide what to show. This makes HTML the s…  ( 5 min )
    Building Stickify: A Digital Sticky Notes App for Developers
    Hey dev.to community! 👋 Ever found yourself surrounded by paper sticky notes with code snippets, meeting notes, and half-baked project ideas?

Try it out: Stickify - Digital Sticky Notes As a developer jumping between multiple projects, my physical sticky note system was a spectacular failure. Notes would fall off my monitor. Get coffee-stained. Pile up until they became a fire hazard. 🔥 I needed something that combined the visual appeal of sticky notes with search functionality that could actually find that brilliant algorithm I scribbled down three weeks ago. So I built it myself. Let me walk you through what I learned. I deliberately kept the tech stack minimal: Vanilla JavaScript (no…  ( 8 min )
    How Java Stores Data in Memory: Writing Efficient Code with Primitives and Non-Primitives
    How Java Stores Data in Memory — Primitives vs Non-Primitives Java is a statically typed language, which means every variable’s type must be known at compile time. This allows the JVM (Java Virtual Machine) to allocate memory efficiently and enforce type safety during execution. Primitive types are the building blocks of data in Java. They have fixed memory sizes and are stored in the stack. The value of a primitive can change, but its size does not. Type Size Description byte 1 byte Smallest integer (–128 to 127) short 2 bytes Short integer int 4 bytes Default integer type long 8 bytes Large-range integer float 4 bytes Single-precision float double 8 bytes Double-precision float char 2 bytes Unicode character boolean 1 bit* True or False (handled as 1 byte internall…  ( 5 min )

    🚫 Top 10 Common Mistakes in Kotlin Programming
    🚫 Top 10 Common Mistakes in Kotlin Programming Treating nullable types as non-null without checks. ✅ Use ?., ?:, and !! carefully. Prefer safe calls and smart casting. !! (Not-null Assertion) Using !! too much can crash the app with NullPointerException. ✅ Use null-safe operators and proper null checks instead. var Instead of val Declaring variables as mutable (var) when they should be immutable (val). ✅ Prefer val for safer, more predictable code. Using apply, let, also, etc., without understanding context. ✅ Choose the right scope function for the right purpose. == and === == checks structural equality, === checks reference equality. ✅ Know when to use each depending on what you're comparing. Not using try/catch when calling risky operations (e.g., parsing, IO). ✅ Always handle exceptions gracefully. Launching coroutines without a proper scope or dispatcher. ✅ Use structured concurrency: lifecycleScope, viewModelScope, etc. Reinventing functions already available (e.g., filter, map, groupBy). ✅ Explore and master Kotlin’s powerful standard library. Not converting Java-style code to idiomatic Kotlin. ✅ Embrace Kotlin syntax, avoid Java habits (e.g., setters/getters, verbose loops). Explicitly declaring types unnecessarily. ✅ Let the compiler infer types where obvious – cleaner and shorter code. Generate exclusive photo for your post  ( 3 min )

    Google Agent Development Kit (ADK) Introduction (5): Developer Mindset
    Conceptual Comparison: Developer Mindset, Responsibility Separation, and Task Decomposition Building on the previous article, this one will explore the shift in developers' mindset when transitioning from API development to A2A development. Developer Mindset Shift: Function-Oriented vs. Agent-Oriented. Traditional development often involves thinking in terms of functions or API call sequences: starting from input, invoking services step-by-step, and finally producing output. Developers act as "orchestrators," controlling every step. In contrast, agent-oriented architecture requires a new mindset—designing a community of agents, each responsible for a subtask and interacting via messages and protocols. Instead of scripting flows directly, developers configure systems of autonomous agents,…  ( 5 min )
    Important Considerations When Using Go's Time Package 9/10
    Understanding == vs Equal() for comparing time When working with time values in Go, one of the most common operations is comparing two timestamps. However, this seemingly simple task can lead to subtle bugs if you're not aware of the differences between using the equality operator (==) and the Equal() method. The equality operator (==) compares all fields of the time.Time struct, including the location information and the monotonic clock reading. This means two times that represent the exact same moment might not be considered equal if they were created in different ways or have different internal representations. t1 := time.Date(2023, time.January, 1, 0, 0, 0, 0, time.UTC) t2 := t1.In(time.FixedZone("UTC-8", -8*60*60)) // These times represent the same instant but have different locati…  ( 13 min )
    Alpha Prototype Complete!
    The first phase of the project, a high-fidelity interactive prototype, is finally complete! This iteration is a sort of detailed rough draft showcasing the design and functionality of the website, mostly using placeholder content. The final straw for this iteration was the addition of the Gallery page. public/gallery/ directory. This means images can be uploaded directly into this folder, and they'll automatically appear with the next site build. To achieve this functionality, the /gallery route is rendered dynamically on the server: export const dynamic = 'force-dynamic'; Rendering the page server-side allows the use of Node's built-in fs module to directly access files on the server: const galleryDir = path.join(process.cwd(), 'public', 'gallery'); let allFiles; try { allFiles = await fs.readdir(galleryDir); } catch (e) { console.error('Could not read gallery directory:', e) allFiles = []; } // Filter to only image files (jpg, png, gif, etc.) const images = allFiles.filter((file) => /\.(jpe?g|png|gif|webp|avif)$/i.test(file) ) I'll be utilizing Statsig to implement feature flags which will allow us to hide and show seasonal Hero sections without interacting with code.

    Understanding *temp and &temp in C++ with strtol
    As a beginner in C++, you might find yourself needing to convert strings to integers, for which you have already encountered functions like atoi and strtol.

    Avoiding nil errors
    Here is a quick way to avoid nil errors and get better failures in Ruby and Ruby on Rails. Convert hashes with known keys into Structs: data = { a: 1, b: 2, c: 3} ... MyData = Struct.new(:a,:b,:c) data = MyData.new(a: 1, b: 2, c: 3) Structs will throw if you introduce a typo instead of returning nil. This tightens your feedback loops and reduces debugging time. hash[:d] => nil struct[:d] => in 'Struct#[]': no member 'd' in struct (NameError) That is cool. What about in more fluid situations like user input? You can convert arbitrary incoming hashes into known structs quickly with the following: params = {a: 1, b: 2, c: 3, x: 9, z: 0} MyData.new(**params.slice(*MyData.members)) While Structs have much the same interface as hashes, there are some tricky differences. Hash#each is equivalent to Struct#each_pair. Hash#keys is equivalent to Struct#members. There is no equivalent to Hash#fetch.  ( 3 min )

    Tokenization could open new opportunities for retail investors to access traditionally restricted asset classes, according to Johann Kerbrat, senior vice president and general manager of Robinhood Crypto, who called it “very important for financial inclusion.” Speaking at the Consensus 2025 event in Toronto, Kerbrat said that some real-world assets, such as real estate and private equity, are available only to up to 10% of the US population. “You need to be an accredited investor to invest in private equity right now,” he said. “How many people can afford a house or an apartment in New York?” he elaborated. “But you can get a piece of it with fractionalization, through tokenization. And so we think it makes it a lot easier to be exchanged, a lot more accessible for everybody.” Robinhood'…
    Filecoin, Lockheed Martin send data in space using decentralized data protocol
    The Filecoin Foundation and Lockheed Martin Space have successfully transmitted data in space using a version of the InterPlanetary File System (IPFS) on a satellite orbiting Earth, Marta Belcher, president of the Filecoin Foundation, told Cointelegraph.  Filecoin and Lockheed Martin adapted the system for use in space and successfully tested it, Belcher said during the Consensus 2025 conference in Toronto. The IPFS enhances privacy and security compared to traditional web protocols, such as HTTP, by identifying data based on its content rather than its location. This has additional benefits for data transmission in space, Belcher said. “The architecture is well-suited to space because it reduces delays, compensates for data corruption caused by radiation, and enables cryptographic verific…
    Sequoia Capital exec also a victim in Coinbase data breach — Report
    At least one partner at Sequoia Capital was reportedly impacted by the recent data breach among Coinbase users, suggesting that data from others at the venture capital firm may also have been compromised. According to a May 16 Bloomberg report, Sequoia Capital Managing Partner Roelof Botha’s personal information available through his Coinbase account was stolen after a group of cybercriminals bribed the exchange’s support agents for access to user data. Though Botha had not publicly disclosed his net worth, estimates suggested he had hundreds of millions of dollars in assets. Coinbase disclosed the data breach in a May 15 blog post, saying that some of its users had been targeted with social engineering attacks after the criminals had access to their personal account information. The company said the group attempted to extort $20 million in exchange for not disclosing the breach, which Coinbase rebuffed. Though the extent of the breach was still unknown, another Bloomberg report suggested that the same type of attacks targeted users at Kraken and Binance. Cointelegraph reached out to representatives from both exchanges but had not received any response at the time of publication. This is a developing story, and further information will be added as it becomes available.
    Solv brings RWA-backed Bitcoin yield to Avalanche blockchain
    Solv Protocol has launched a yield-bearing Bitcoin token on the Avalanche blockchain, giving institutional investors more exposure to yield opportunities backed by real-world assets, or RWAs. On May 16, the protocol unveiled SolvBTC.AVAX, a token that connects Bitcoin (BTC) to real-world assets like US Treasurys and private credit offered by BlackRock and Hamilton Lane.  The new token was developed through a seven-way partnership involving Solv, Avalanche, Balancer, Elixir, Euler, Re7 Labs, and LFJ, the company said.  Solv Protocol founder Ryan Chow said the token is a way to link Bitcoin to “real-world economic cycles” in uncorrelated assets such as US government bonds and private credit, as opposed to BTC’s typical boom-and-bust four-year cycle. The token uses a multi-protocol strategy t…
    Altcoins are on the verge of ‘most powerful rally’ since 2017 — Analyst
    Key takeaways: The total altcoin market cap (excluding ETH) gained $126 billion in Q2, fueling speculation of an altseason. The altcoin market cap, excluding Ether (ETH), has added $126 billion in Q2, sparking enthusiasm from analysts who have been waiting for an altseason. Crypto analyst Javon Marks noted a breakout that could rival the explosive 2017 bull run.  In a recent post on X, Marks highlighted a chart comparing the TOTAL3 index (total market cap of altcoins excluding Bitcoin (BTC) and Ethereum) against the US money supply, suggesting that altcoins may be on the verge of a significant rally.  A rise in TOTAL3 against the US money supply suggests that altcoins are gaining value relative to the total liquidity in the US economy, reflecting increased investor interest and capital i…
    Galaxy Digital lists on Nasdaq, seeks to tokenize shares — Reports
    Galaxy Digital shares began trading on the Nasdaq stock exchange May 16, completing a years-long process that CEO Mike Novogratz called unfair and infuriating, CNBC reported. The crypto and infrastructure company, which is also listed in Canada, opened trading at $23.50 in its Nasdaq debut. Trading began on the same day Galaxy disclosed that it is working with the US Securities and Exchange Commission (SEC) to tokenize its shares. According to Bloomberg, the tokens representing Galaxy Digital’s shares could be used in decentralized finance applications, like borrowing or lending. Galaxy is among several crypto companies looking to access the US markets under a friendlier regulatory regime in the country. Companies that are also exploring or working on a US listing include Metaplanet, Circ…
    Bitfinex Bitcoin longs total $6.8B while shorts stand at $25M — Time for BTC to rally?
    Key takeaways: Bitfinex margin longs fell 18%, despite Bitcoin price rising 24% in 30 days. $6.8 billion in long positions far outweight the current $25 million in shorts. Bitcoin options positioning and spot BTC inflows point to confidence from institutional investors. Bitcoin (BTC) price climbed 23.7% over the past 30 days, yet traders on Bitfinex have cut their leveraged long positions by more than 18,000 BTC during this time. This wave of profit-taking in margin markets has led to speculation that professional traders may not be fully confident in the current $104,000 price level. Bitfinex BTC margin longs, BTC.

    World Liberty Financial brushes off oversight concerns from Congress
    Zach Witkoff, one of the co-founders of the Donald Trump family-backed crypto platform World Liberty Financial (WLFI), has rebuffed efforts by US lawmakers to investigate the president’s potential conflicts of interest. In a May 15 letter to Senator Richard Blumenthal, lawyers for World Liberty Financial claimed a call to investigate the crypto platform was based on “fundamentally flawed premises and inaccuracies.” Witkoff did not specifically address any allegations, claiming that WLFI was “too busy building” for oversight. “The Company rejects the false choice between innovation and oversight,” said the letter. “What it opposes is the misuses of regulatory authority and uncertainty to suppress lawful innovation.” May 15 letter to Sen.

    Judge sentences SEC hacker to 14 months in prison
    A federal judge has sentenced Eric Council Jr., one of the individuals responsible for posting a fake message announcing regulatory approval of spot Bitcoin exchange-traded funds, to 14 months in prison. Following a May 16 hearing in the US District Court for the District of Columbia, the Justice Department announced that Council would serve 14 months in prison after pleading guilty to one count of conspiracy to commit aggravated identity theft and access device fraud. He was part of a group that compromised the X account of the US Securities and Exchange Commission (SEC) in January 2024 and said the regulatory body would be approving spot Bitcoin (BTC) ETFs. Prosecutors had requested that the judge impose a two-year sentence, while Council’s lawyers asked for one year and one day. Court filings showed he earned roughly $50,000 through SIM swap attacks like the one that compromised the SEC’s X account — funds likely subject to forfeiture. This is a developing story, and further information will be added as it becomes available.
    CFTC commissioner to leave agency on May 31
    Christy Goldsmith Romero of the US Commodity Futures Trading Commission (CFTC) will step down on May 31, leaving three seats open at the financial regulator. In a May 16 announcement, Romero said her last day at the agency would be on May 31, ahead of her initial plans to leave if the Senate confirmed former commissioner Brian Quintenz as the new chair. Her departure will come just one day after Commissioner Summer Mersinger is expected to step down to join the crypto advocacy organization the Blockchain Association as CEO. “It has been a tremendous honor to conclude my 23 years of federal service at an agency with such an important mission to ensure that financial markets perform their critical role in the US and global economies,” said Romero. Romero and Mersinger’s upcoming departures would leave the CFTC with only two Senate-confirmed members: acting chair Caroline Pham and Commissioner Kristin Johnson, each taking one Republican and Democratic seat, respectively. The shakeup in leadership gives President Donald Trump the opportunity to pick two more commissioners after the Senate addresses Quintenz’s nomination. This is a developing story, and further information will be added as it becomes available.
    Basel Medical shares down 15% on $1B Bitcoin buying plans
    Shares of Basel Medical Group are down around 15% after the healthcare company announced plans to buy $1 billion in Bitcoin for its corporate treasury.  On May 16, Singapore-based Basel said it was “in advanced discussions with a consortium of institutional investors and high-net-worth individuals […] to acquire a US$1 billion BTC through an innovative share-swap arrangement. The company said the benefits of its planned purchase include creating “one of the strongest balance sheets among Asia-focused healthcare providers” and providing “unmatched financial flexibility for mergers and acquisitions.” It also said the Bitcoin (BTC) treasury would help Basel “[e]stablish “a diversified asset base to weather market volatility.” But the company’s shareholders weren’t sold.

    Price predictions 5/16: BTC, ETH, XRP, BNB, SOL, DOGE, ADA, SUI, LINK, AVAX
    Key points: A Bitcoin price close above $105,000 could accelerate momentum and trigger a rally to $130,000. Ether continues to gain strength, which is being mirrored by many altcoins. Bitcoin (BTC) has been consolidating between $100,718 and $105,819 for the past few days, indicating a balance between supply and demand. A positive sign is that the price has held above the psychologically crucial $100,000 level, signaling that the bulls are hanging on to their positions as they anticipate another leg higher.

    Bitcoin supply crunch boosts confidence in $200K target for 2025 — Bitwise CIO
    Matt Hougan, chief investment officer at Bitwise, predicts Bitcoin (BTC) will reach $200,000 by the end of 2025 due to a supply shock from heightened institutional demand. In an interview with Cointelegraph at Consensus 2025 in Toronto, the executive said that Bitwise's Bitcoin price prediction model is driven exclusively by supply and demand metrics. Hougan laid out the specific figures driving the forecast: "We know that miners will produce 165,000 BTC this year. Already, publicly traded companies have bought more than that. ETFs are at $6 billion in inflows. We think governments are going to be buying. We see this sort of structural difference between demand and supply."

    US Senate will pass Stablecoin bill — Digital Chamber chief

    Europe’s MiCA law is motion, but can the crypto industry keep up?
    The European Union’s Markets in Crypto-Assets regulation — better known as MiCA — is now in its critical implementation phase. Designed to unify crypto regulation across all 27 EU member states, MiCA promises clarity, consumer protection and long-term market stability. But as implementation begins, cracks are already showing. In this week’s episode of Byte-Sized Insight, we explore the key provisions of MiCA now in force, particularly around stablecoins, and why some of the largest players in the market are refusing to comply. As of January 2025, crypto asset service providers (CASPs) began acquiring licenses to operate legally within the EU. A transitional or “grandfathering” period allows existing firms up to 18 months, depending on the member state, to comply. Still, with deadlines app…

Jameson Lopp’s GitHub repository, which logs such incidents, has recorded 22 “$5 wrench” attacks on crypto holders in 2025 alone. The moniker comes from the crude and violent methods perpetrators use to compel crypto holders to hand over their bags.  In many cases, local law enforcement can intervene before anyone is harmed and funds are lost. But there is a growing trend of increasingly violent and successful attacks, some of which have resulted in permanent harm and even death.

    51% attack on Ethereum more difficult than on Bitcoin — Justin Drake
    Ethereum Merge architect Justin Drake told Cointelegraph that it would be cheaper to launch a 51% attack on Bitcoin than on Ethereum. Drake said it would be “much cheaper to 51% attack Bitcoin” and that it would cost “on the order of $10 billion.” Drake led work on Ethereum’s proof-of-stake (PoS) implementation and was a principal architect in the Merge (the full PoS transition event). His remarks echo a May 14 X post by Grant Hummer, the co-founder of Ethereum-focused marketing and product company Etherealize. In the post, Hummer said that Bitcoin “is completely screwed because of its security budget.” Hummer claimed it would cost $8 billion to run a successful 51% attack, and said a successful attack is “virtually certain” when the cost slips to $2 billion.

    Animoca’s Yat Siu says student loans can supercharge DeFi growth
    Bringing student loans onchain would increase the total value locked (TVL) in decentralized finance (DeFi) by more than four times, supercharging the industry, according to Yat Siu, chairman of Animoca Brands. Speaking at Consensus 2025 in Toronto, Siu pointed to the $3 trillion global student loan market as an untapped opportunity for the crypto industry.

    Is XRP price going to crash again?
    Key takeaways: XRP is retesting a falling wedge breakout, which could lead to a rally toward $3.60. Whale wallets are in the red, and history shows this isn’t bullish for XRP price.

    Stablecoin bill passes in Northern Marianas as House overrides veto
    The Pacific US territory of the Northern Mariana Islands has passed a bill allowing its small constituent island of Tinian to launch a stablecoin, overriding an earlier veto by the territory’s governor. The 20-member Northern Mariana Islands House voted 14-2 to undo Governor Arnold Palacios’ April 11 veto of the bill, which allows the Tinian local government to issue licenses to internet casinos and includes a provision for the Tinian treasurer to issue, manage and redeem a “Tinian Stable Token.”  The territory’s nine-member Senate had revived the bill on May 9, voting 7-1 in a two-thirds majority to override the veto, which then needed a two-thirds majority in the House to pass.

    AI scammers are now impersonating US government bigwigs, says FBI
    Deepfake-assisted hackers are now targeting US federal and state officials by masquerading as senior US officials in the latest brazen phishing campaign to steal sensitive data.  The bad actors have been operating since April, using deepfake voice messages and text messages to masquerade as senior government officials and establish rapport with victims, the FBI said in a May 15 warning.  “If you receive a message claiming to be from a senior US official, do not assume it is authentic,” the agency said.   If US officials’ accounts are compromised, the scam could become far worse because hackers can then “target other government officials, or their associates and contacts, by using the trusted contact information they obtain,” the FBI said.  As part of these scams, the FBI says the hackers a…

Deputy Attorney General Todd Blanche’s April memo said the Justice Departmen…

    Legacy forex, payments platforms ‘hate’ stablecoin adoption — Kevin O’Leary
    Global foreign exchange and payments platforms are lobbying hard against stablecoins, which stand to significantly disrupt their business models, investor Kevin O’Leary said during a keynote address at Consensus 2025. Legacy forex and payments platforms often extract large fees for servicing cross-border cash transfers and stand to lose out on revenue if regulated stablecoins become accepted as a cheaper, faster alternative, O’Leary said at the Toronto conference.  “Currency trading is a multi-trillion dollar market — and it’s old and ugly and inefficient,” O’Leary said, adding that “[ t]he biggest threat to that monopoly or oligopoly is a regulated stablecoin.”  “Once that’s approved, the multi-trillion dollar FX market becomes efficient, transparent, and inexpensive,” he said.  Kevin O’…
    Trump’s crypto ties ‘add a certain level of challenge’ to passing bills — Coinbase exec
    Coinbase chief legal officer Paul Grewal addressed some of the concerns raised by US lawmakers and industry leaders around President Donald Trump’s crypto ventures, and how they may affect related legislation. Speaking at the Consensus conference in Toronto on May 15, Grewal said there had been “hiccups” in Congress since the Senate Banking Committee voted to advance the Guiding and Establishing National Innovation for US Stablecoins, or GENIUS Act, in March. Though Grewal said there were disputes over “substantial issues that need to be addressed” in the bill, he hinted that Trump’s involvement in the industry was a “complicating factor.”  “The discussion around the president's support for a certain memecoin or two and other efforts does add a certain level of challenge to the effort to g…
    "The world is trying to hoard Bitcoin right now" — Eric Trump
    There is an ongoing race across the world for Bitcoin accumulation, according to Eric Trump, the second-eldest son of US President Donald Trump. Speaking at a crypto conference in Toronto on May 15, Trump said that from families to government funds, “everybody in the world is trying to hoard Bitcoin right now.” The remarks came during a panel at Consensus 2025. Sharing the stage with Asher Genoot, the CEO of Bitcoin (BTC) mining company Hut 8, Trump said Bitcoin adoption has been incredible. “I'm traveling. I'm on a plane.

    Bitcoin traders’ evolving view of BTC’s role in every portfolio bolsters $100K support
    Key takeaway: Bitcoin’s struggles to overtake the $105,000 level as US macroeconomic headwinds remain a challenge. Steady inflows from institutional investors and the strength of the $100,000 support point to growing confidence in Bitcoin. Bitcoin (BTC) has struggled to break above $105,000 since May 10, leading traders to question whether the bullish momentum has faded. Although BTC managed to reclaim the $104,000 level, demand for leveraged long positions has dropped sharply, as indicated by the decline in the Bitcoin futures premium.   Bitcoin 2-month futures annualized premium.

    Asset tokenization expected to speed capital flows, says Chainlink's Nazarov
    Asset tokenization is set to accelerate the movement of capital across traditional markets, according to Chainlink co-founder Sergey Nazarov.

"I think that there are two sides to this equation. One is the asset, and the other one is the payment. So, you need more high-quality assets onchain, but you also need more frictionless payments that existing institutions can use easily," Nazarov said on May 14.

    Bitdeer Q1 revenue falls more than 40% year-over-year
    Bitdeer Technologies Group reported a 41% year-over-year drop in revenue to $70.1 million for the first quarter of 2025, the Bitcoin miner said on May 15.  The Singaporean company clocked an operating loss of $3.2 million for the quarter, down from a $34.1 million profit during the same period last year, its earnings release said.  However, Bitdeer reported a Q1 net income of more than $400 million, largely driven by gains on convertible notes and warrants issued to stablecoin issuer Tether in 2024. Bitdeer’s revenue declines come as miners increasingly expand beyond Bitcoin (BTC) mining and pivot toward supplying high-performance computing (HPC) for artificial intelligence applications.  “As we scale self-mining and execute on our ASIC [mining hardware] roadmap, we are also advancing plan…

    Stablecoin regulation 'next catalyst' for crypto industry — Aptos head
    Stablecoin regulation is “the next catalyst” for the crypto industry and could lead to unprecedented “appetite from institutional investors,” according to Ash Pampati, head of ecosystem at the Aptos Foundation. In an interview with Cointelegraph at Consensus 2025 in Toronto, Pampati said that “the whole world outside of the United States […] has already jumped onto this [stablecoins],” adding that “the US is [...] at the doorstep.” “I really think about new use cases that can emerge because of the borderless nature of stablecoins, because of the efficiency of the dollar onchain,” he said. “If you're trying to send money to your friend in Nigeria, why do you have to go through a bunch of hoops?” Stablecoins are often used to transfer money across borders, as they are easier and cheaper to …

Bitcoin (BTC) price has rebounded by 36% from its April 9, five-month low at $74,500.

    Canada lags with stablecoin approach, but there’s room to catch up
    The slow adoption of stablecoins in Canada has some local crypto industry observers concerned that the country is falling behind. The Canadian Securities Administrators (CSA) classified stablecoins as “securities and/or derivatives” in December 2022 after the FTX debacle that shook markets and turned many lawmakers against the crypto industry. Regulating stablecoins as a security has seen few local stablecoin issuers arise, but in the United States and the European Union, softening regulations have seen significant growth in the stablecoin market. This makes Canada, observers say, less competitive with other jurisdictions.  Of particular concern is the perceived gap in peer-to-peer (P2P) payments in Canada, which stablecoins are uniquely qualified to fill.  Stablecoins globally have grown …
    Coinbase fires compromised agents in India— Report
    Coinbase has reportedly fired a group of customer support agents following their alleged involvement in social engineering attacks on users. The contracted agents were based in India. According to a May 15 Fortune interview, Coinbase's chief security officer, Philip Martin, said the company flagged customer support contractors who allowed scammers access to user data, suggesting they could be Indian nationals. The CSO’s comments came after some crypto users reeled from attempted phishing attacks using their Coinbase data, which the exchange estimated could cost them between $180 million and $400 million in remediation and reimbursement. Qiao Wang, a core contributor to Alliance DAO, said in a May 15 X post that he may have been a victim of one of these attacks. He said a scammer notified him his Coinbase account had been compromised, asked him to verify his personal information, to which the criminals likely had access through the compromised agents, and requested he withdraw all his funds to a “Coinbase self-custodial wallet.” “I called them out at the end of the call telling them they need to step up their game [...],” said Wang on X. “They told me that had made $7m that day.” Cointelegraph reached out to Martin and Coinbase for comments, but had not received responses at the time of publication. This is a developing story, and further information will be added as it becomes available.
    Spot Bitcoin ETF inflows fall, but BTC whale activity points to bull market acceleration
    Key takeaways: Spot Bitcoin ETF inflows dropped over 90% from $3 billion to $228 million in four weeks. While strong ETF inflows often drive Bitcoin rallies, recent data shows price movements can occur independently. Despite short-term selling pressure, long-term BTC whale buying suggests a potential continuation of the BTC uptrend. The Bitcoin (BTC) market posted a 90+% drop in spot BTC exchange-traded fund (ETF) inflows, falling from $3 billion in the last week of April to just $228 million this week. Historically, a slowdown in ETF inflows has impacted BTC price, notably when daily inflows averaged over $1.5 billion for consecutive weeks. To understand the potential impact on Bitcoin, let’s examine four key periods of significant spot ETF activity and their correlation with BTC pri…
    The AI revolution won’t be centralized — Superior agents are coming for Big Tech’s crown
    Opinion by: Jennifer Dodgson, co-founder of KIP Protocol and Eigenform AI The puppet show is ending. The Brookings Institution found that generative artificial intelligence may disrupt at least 50% of tasks performed by more than 30% of all workers. The same study also estimates that genAI may affect at least 10% of tasks performed by approximately 85% of the human workforce. The TL;DR from these stats? AI’s effects are likely to be both broad and deep. If AI doesn’t already scare you, self-learning AI agents that autonomously achieve goals may fix that. Forget your sanitized ChatGPT conversations and bland AI assistants. Superior agents are AI that autonomously achieve human-set objectives by any means necessary. While OpenAI’s valuation of $300 billion benefits the few rather than the ma…
    What the 10-year Treasury yield means for crypto yields and stablecoins
    Understanding the 10-year Treasury yield: Definition and importance The 10-year Treasury yield is the interest rate that the US government pays to borrow money for 10 years. When the government needs cash, it issues bonds called Treasury notes, and the 10-year note is one of the most watched. The “yield” is the annual return you’d get if you bought that bond and held it until it matures. It’s expressed as a percentage, like 4% or 5%. Think of it as the government saying, “Hey, lend me $1,000, and I’ll pay you back in 10 years with some interest.” That interest rate and the yield move up or down based on demand for the bonds, inflation expectations and the overall economy. Because US Treasurys are considered safe (the government isn’t likely to def…

    Tether blacklist delay allowed $78M in illicit USDT transfers: Report
    A lag in Tether’s wallet blacklisting process allowed over $78 million in illicit funds to be moved before enforcement actions took effect, according to a new report from blockchain compliance company AMLBot. Tether’s address blacklisting becomes effective only after a considerable delay from when the process is initiated on Ethereum and Tron, according the report published May 15. “This delay originates from Tether’s multisignature contract setup on both Tron and Ethereum, transforming what should be an immediate compliance action into a window of opportunity for illicit actors,“ the report reads.

    Bitcoin mining 2025: Post-halving profitability, hashrate and energy trends
    After the 2024 halving, Bitcoin mining entered its fifth epoch and block rewards were reduced from 6.25 BTC to 3.125 BTC.

    Tariff doubts push NFL, NBA to bet big on digital merch

Bitcoin (BTC) will shoot to $1 million in just three years thanks to global macroeconomic shifts, Arthur Hayes forecasts. In his latest blog post released on May 15, the former CEO of crypto exchange BitMEX doubled down on his sky-high BTC price prediction. Hayes: $1 million Bitcoin due “between now and 2028” Bitcoin has two giant tailwinds that will help propel it to seven digits in just a few years. For Hayes, shifting capital controls worldwide, as well as US treasury “devaluation,” mean that Bitcoin wi…
    Jim Chanos takes opposing bets on Bitcoin and Strategy
    Prominent short-seller Jim Chanos, once a vocal critic of Bitcoin and cryptocurrencies, revealed a new trading play that involves shorting shares of Strategy (formerly MicroStrategy) and buying Bitcoin. At the Sohn Investment Conference in New York, Chanos told CNBC he’s “selling MicroStrategy stock and buying Bitcoin.” The investor described the move as buying something for $1 and selling something for $2.50, referring to what he sees as a significant price mismatch. Chanos argued that Strategy is selling the idea of buying Bitcoin (BTC) in a corporate structure, and that other companies are following suit in hopes of receiving a similar market premium. Chanos said this was “ridiculous.” He described his trade as “a good barometer of not only just the arbitrage itself, but I think of reta…
    Stablecoins seen as ideal fit for real-time collateral management
    Cryptocurrencies and stablecoins are gaining recognition in the traditional finance (TradFi) space for their ability to streamline payments and increase efficiency in existing financial systems In finance, collateral management refers to the process of managing the underlying collateral securing other financial transactions, such as loans or derivatives, to mitigate credit risks and ensure smooth transactions. Digital assets like stablecoins are the “perfect” financial instrument for real-time collateral management, according to a recent pilot by DTCC Digital Assets, which suggests that digital assets, particularly stablecoins, could modernize and simplify this critical function. “Digital assets really are the perfect use case for collateral management, whether it be uncleared derivatives,…
    Coinbase faces $400M bill after insider phishing attack
    Coinbase, the world’s third-largest cryptocurrency exchange, was hit by a $20 million extortion attempt after cybercriminals recruited overseas support agents to leak user data, the company said. According to a May 15 blog post, Coinbase said a group of external actors bribed and coordinated with several customer support contractors to access internal systems and steal limited user account data. “These insiders abused their access to customer support systems to steal the account data for a small subset of customers,” Coinbase said, adding that no passwords, private keys, funds or Coinbase Prime accounts were affected. Less than 1% of Coinbase’s monthly transacting users’ data was affected by the attack, the company said. Source: Coinbase After stealing the data, the attackers attempted to …

    Pareto launches synthetic dollar backed by private credit
    Private credit marketplace Pareto has introduced a new synthetic dollar aimed at linking institutional investors with decentralized finance (DeFi) opportunities — a move that highlights the expanding role of stablecoins in global finance. The newly launched USP synthetic dollar is fully backed by real-world private credit, Pareto told Cointelegraph on May 15. To mint USP, users must deposit stablecoins such as USDC (USDC) and USDt (USDT), which are then held as collateral. “USP is backed 1:1 by the stablecoins used during the minting process,” Pareto co-founder Matteo Pandolfi told Cointelegraph in a written statement. The deposited funds are placed into Pareto’s credit vaults and lent to what the company describes as “vetted institutional borrowers,” generating yields for participants. To…
    Ukraine strategic Bitcoin reserve bill reportedly in final stages
    Ukraine is reportedly moving closer to adopting Bitcoin as a national reserve asset, a move that could bolster its financial resilience amid the ongoing war with Russia. Lawmakers are reportedly working on a Bitcoin (BTC) national reserve proposal, with a draft bill in its final stages, according to Yaroslav Zhelezniak, a member of parliament who confirmed the plan to local media outlet Incrypted.

    Coinbase’s x402: Crypto payments over HTTP for AI and APIs
    What is HTTP 402, and why does it matter? The web was not really built with payments in mind, especially not for autonomous agents or machines. But with the rise of AI and decentralized finance (DeFi), the need for seamless, native digital payments has never been more urgent.  Coinbase x402 announced a new open protocol designed to let APIs, apps and AI agents pay instantly using stablecoins like USDC (USDC), all via the familiar HTTP protocol.

    The value of virtual: Economies are powered by ownership of the intangible
    Opinion by: Yat Siu, executive chairman and co-founder, Animoca Brands A discussion on digital property rights, copyright, intellectual property, the open metaverse, AI and value without physical form. When I attend conferences and similar public events, someone almost always approaches me to ask how cryptographic tokens (fungible or non-fungible) can have value even though tokens are virtual and do not exist in the physical world. It's a surprisingly common question, especially one-on-one. Virtual objects like NFTs and cryptocurrencies are both digital and intangible; their existence is not based in the real (physical) world, and (unlike digital currencies) they generally do not have backing by real-world institutions.  The ability to have value (specifically, monetary worth) is crucially…

    NFT founder stole millions from Bitcoin project, investors allege

According to the May 14 court filing in Illinois, the plaintiffs allege that their former business partner, Jonathan Mills, lied about transferring assets from Hashling NFT and at least $3 million from the Bitcoin mining project to a holding company — Satoshi Labs LLC (formerly known as Proof of Work Labs LLC), which Mills is the founder and CEO of. The plaintiffs have sued Mills for fraud and breach of fiduciary duty, claiming that they have not received any of the equity returns that he supposedly promised.  They also claim to have raised a combined $1.46 million from two NFT drops …

Sonic Labs CEO Michael Kong said in a May 14 statement to X that the team behind the layer 1 Sonic blockchain felt it had no choice but to file a lawsuit to forcibly wind up Multichain because its former employees were being “completely uncooperative” and “hid from victims.” “Going forward, the liquidators can now start working with other parties to initiate the process of trying t…
    Senate removes Trump provisions in push to pass stablecoin bill
    The US Senate could pass a key bipartisan stablecoin bill as soon as next week after removing language targeting President Donald Trump and his family’s sprawling crypto interests. Republican Senator Cynthia Lummis said onstage at an event by Coinbase’s lobbying arm, Stand With Crypto, that she thinks it's a “fair target” to have the Guiding and Establishing National Innovation for US Stablecoins Act, or GENIUS Act, passed by May 26 — Memorial Day in the US. Joining her onstage was Democratic Senator Kirsten Gillibrand, who hinted that the bill’s language was changed to scrap provisions that targeted Trump’s various crypto projects, which include memecoins, a crypto platform, a stablecoin and a crypto mining company that plans to go public, among others. “When this language comes out, peop…

    Chainalysis CEO offers a clue into the recent spate of Paris crypto attacks
    Some criminal organizations are yet to receive the memo — crypto is traceable — and could explain the recent string of crypto-related kidnappings, says Chainalysis CEO Jonathan Levin.  Law enforcement has been increasingly successful at tracing stolen funds and crypto ransom payments, resulting in a “lot of arrests,” Levin said during the 2025 Consensus crypto conference, covered by Cointelegraph. “For whatever reason, there is a perception that’s out there that crypto is an asset that is untraceable, and that really lends itself to criminals acting in a certain way,” he said.  “Apparently, the know that crypto is not untraceable hasn't been received by some of the organized crime groups that are actually perpetrating these attacks, and some of them are concentrated in, you know, France, b…

    Europol helps dismantle $23M ‘mafia crypto bank’
    European law enforcement in January arrested 17 suspects of a “mafia crypto bank” who are said to have laundered over 21 million euros ($23.5 million) in crypto for criminal entities in China and the Middle East.

So that makes it very hard for us to make a return for our liquidity providers,” Tapeiro said while speaking in a panel discussion at the Consensus conference in Toronto on May 14. “So a lot of those deals we just pass almost automatically, even businesses that we really like, we won't invest in if the price isn't reasonable in the beginning.” 10T Holdings has passed on over 200 companies for similar reasons, including the now-bankrupt FTX, BlockFi and Celsius, Tapeiro sai…

    Key takeaways: Google search data and app rankings show retail Bitcoin investor demand near 6-month lows. Retail investor interest typically peaks 1 week after BTC breaks all-time highs.

    How to Validate Data for BMP Character Encoding in Java?
    Introduction In Java programming, ensuring the integrity of data being inserted into a database is crucial. If your database is set to utf8 encoding, it limits you to characters within the Basic Multilingual Plane (BMP), specifically from U+0000 to U+FFFF. This means that characters beyond this range, such as emoticons and certain rare characters, will not be supported. To maintain this limit without switching to utf8mb4, it’s essential to validate the input data on the backend. In this article, we'll explore effective methods to perform this validation using regular expressions and Java code examples. Why BMP Character Encoding Matters The BMP is the first plane of Unicode, containing the most commonly used characters in modern languages, music notations, and some symbols. Using the utf8 …  ( 5 min )
    Kickstarting a .NET Solution from Scratch with the CLI
    Introduction You can use this article as a cheat sheet or a starting point to mastering the CLI. The CLI is one of the most essential tools in a software engineer's toolbox. As useful as it is, it can feel a little intimidating for many developers (especially on the very first encounter). Others get excited. I remember seeing the terminal for the first time and thinking, "whoa, that looks super cool, I want to master it. NOW!" But the CLI wasn't built to impress or scare anyone (especially not scare). It was designed to make our lives easier by providing the simplest form of interface possible. As developers, we should always strive for simplicity—our job is already hard enough without adding layers of unnecessary complexity. The CLI isn't only about simplicity—it's the universal tool. Y…  ( 7 min )
    Automating My Docker Apache Server with Python
    After building my first Docker project, I knew I couldn’t stop there. The Dockerfile worked perfectly, the image deployed, and Apache ran inside its own containerized environment. But there was still one essential piece missing: 🚀 Automation ✨ So I built it. In my previous article, I walked through setting up a full Dockerized Apache server workflow—building a Docker image, pushing it to Docker Hub, and deploying it in a custom Docker network. You can check out that full breakdown here: 👉 End-to-End Docker Apache Server: Build, Push, and Networked Deploy Docker CLI is great, but typing in the same sequence of commands repeatedly isn’t efficient—especially when you’re building and deploying containers frequently. Using Python (and the official Docker SDK for Python) allows us to: Automate…  ( 5 min )
    Why Doesn't My Android Device Show Up in IntelliJ IDEA?
    If you're experiencing issues with your Android device not showing up in IntelliJ IDEA despite it being recognized via ADB and the command line, you're not alone.

    Why Developers Seek an Auth0 Alternative
    Many projects start out happily on Auth0’s free tier (up to ~7,000 MAUs), but the jump to the paid Basic plan—\$525/month for 7.5K active users—can sting fast. Beyond raw cost, teams worry about unpredictable bills, feature lock-ins, and vendor dependence. Cloud-Provider Auth Services AWS Cognito, Azure B2C, Google Identity Platform Virtually free until very high volumes, but may lack out-of-the-box UI customization. Backend-as-a-Service (BaaS) Firebase Auth (free up to 50K users/month) Supabase Auth PocketBase (self-hosted) SSOJet, Clerk.dev, Stytch, Kinde All offer generous free tiers and modern SDKs Self-Hosted Open-Source Keycloak, Ory Kratos, Supertokens, Authgear Full control and zero license fees, at the cost of hosting and maintenance overhead. Build-Your-Own Roll your own JWT-based login (e.g., using Passport.js or a simple email/password flow) Simplest for very small scale but requires ongoing security diligence. Scale & Budget: Calculate total cost at your expected growth, not just free-tier limits. Feature Requirements: Do you need MFA, SSO/SAML, social logins, or multi-tenant support? Maintenance Overhead: Self-hosting shifts burden to your team; hosted solutions offload ops at a price. Vendor Lock-In: Check data export and migration paths—some providers don’t let you export password hashes. Community & Support: A vibrant open-source community (Keycloak, Ory) or strong commercial SLAs (SSOJet, Clerk, Stytch) can save you headaches down the road. By weighing cost, complexity, and required features, you can pick a path that fits both your technical needs and your wallet—whether that’s a serverless BaaS, a self-hosted IAM, or even a custom-built solution.

    How Does an Ai name Generator Work?
    An AI name generator works by using algorithms—often powered by machine learning or natural language processing (NLP)—to create names that meet specific criteria or patterns. Here’s a breakdown of how they typically function: 🔧 1. Input Parameters Type of name (fantasy, sci-fi, business, product, etc.) Gender (for character names) Language or cultural origin Length or syllables Desired traits (e.g., futuristic, elegant, tough) 🧠 2. Model or Algorithm Rule-Based Systems Good for simple, consistent naming schemes. Limited creativity or adaptability. Markov Chains E.g., if trained on Elvish names, it will produce similar-sounding results. Neural Networks / Language Models Understand phonetics, style, and semantic nuances. Capable of generating unique and creative names that still "fit" a theme. Examples: GPT (like me), LSTMs, or transformer-based models. 🧾 3. Filtering and Validation Check for offensive or inappropriate content Filter by length, pronounceability, or domain availability (for businesses) Remove duplicates or overly similar results 🎨 4. Post-Processing Capitalized or stylized Modified for branding (e.g., removing vowels, adding suffixes like "-ify" or "-ly") Example: Take a dataset of known elf names (e.g., from Tolkien or D&D) Learn common phonemes or structures (e.g., soft consonants, vowel-heavy syllables) Generate something like "Elarion" or "Thalindra" Some of the example of toosls are: Elden Ring Name Generator , Tiefling Name Generator , Khajiit Name Generator  ( 3 min )

    What it’s like to be a software developer with tinnitus
    First of all, what is it like to have tinnitus? I would say, in short, it sucks. It’s a piece of quality of life that has been lost and you never experience absolute silence again. Can you live with it? Yes! Can you work as a software developer with it? Yes, of course! But it has to be said, a constant, persistent beep is a distraction, especially when a deep focus on a task is needed. I would like to make a few points about how I deal with this, especially when developing software. The first (perhaps most important for me) step in dealing with this was acceptance. In the beginning I felt shame, anger and even fear. However, with the acceptance of this new fact, it got better and my head was clearer again. I looked for nice, relaxing sounds and played them in the background. The beeping is always there, so why not cover it up with something beautiful that you like and brings you joy, I thought to myself. There are countless playlists for all kinds of sounds on the streaming platforms, such as nature and night rain. I take regular breaks and rest my body and mind during this time. In my opinion, a working day, however stressful it may be, should have at least one longer lunch break with fresh air (I’m still working on this). Nevertheless, the lunch break is an integral part of every situation where I don’t think about work for 30 minutes and recharge my batteries. I have already set up my workstation ergonomically. Of course, there’s always room for more. A desk that can be raised and lowered is a great thing. Correct posture is extremely important. I’m still at the beginning in this area and am always looking at where I can improve. Ok ok I know, admittedly sounds, pauses and ergonomics aren’t big new pro tips. I would rather like to say that this impairment loses its power when you exhaust all other possibilities and start optimizing. You should concentrate on the things you can influence and make the best of them!  ( 4 min )
    Efficient Cache Design with Bloom Filters in Go
    In cache design, we often encounter a troublesome problem: a large number of “invalid queries” put tremendous pressure on the database. For example, when a user requests data that doesn’t exist, we typically query the database, which returns “not found.” If there are many such requests, the database gets busy handling these meaningless queries, affecting system performance. So, is there a way to know in advance whether data “might exist” before querying? This is where Bloom filters come into play. Imagine the following scenario: Our system has a cache layer (Redis) and a database layer (MySQL). When a user requests some data, we first check the cache. If it’s a cache hit, we return the result directly. If the data isn’t in the cache, we query the database. If the database doesn’t have it e…  ( 7 min )

    This is a submission for the Permit.io Authorization Challenge: Permissions Redefined NB: This article was posted after the submission deadline for the Permit.io dev challenge. Finding players for a casual game of soccer can be a headache — organizing who's in, who's out, and when to start often takes more time than the actual match. I built Little League to fix that. This simple web app allows players to queue into 3-a-side soccer matches. The first three players are assigned to Team A, and the next three to Team B, all handled automatically. Each team is given a randomly generated team name using the unique-names-generator package to add some personality and fun to each match. Behind the scenes, Permit.io handles all fine-grained authorization to keep role-based access secure and easy t…  ( 4 min )
    How to Handle Dialog and Back Button Issues in Flutter?
    Introduction In recent Flutter updates, particularly with version 3.29.2 and beyond, some developers are noticing unexpected behavior when dismissing dialogs and using the system back button. The warning log, such as W/WindowOnBackDispatcher(5980): sendCancelIfRunning: isInProgress=false callback=androidx.activity.OnBackPressedDispatcher$Api34Impl$createOnBackAnimationCallback$1@6f8e0ef, typically indicates that there’s an ongoing operation when the back button is pressed.

Understanding the Issue When you are working on a Flutter application and present a dialog, the app's navigation state can become momentarily …  ( 5 min )
    Event Loop Phases: Microtasks vs. Macrotasks in Depth
    Event Loop Phases: Microtasks vs. Macrotasks in Depth JavaScript, touted for its non-blocking execution model, employs a sophisticated mechanism known as the Event Loop. This mechanism enables asynchronous programming, which is a cornerstone of modern web applications. The Event Loop consists of various phases, with two critical categories of task handling: Macrotasks and Microtasks. Understanding the differences, interactions, and implications of these tasks can deeply influence how developers structure their applications for optimal performance and responsiveness. JavaScript was developed by Brendan Eich in just ten days in 1995, largely influenced by various programming paradigms. Initially, it was designed to facilitate dynamic client-side scripting in web browsers. With the inclusio…  ( 6 min )
    Vibe Coders Are Ruining Software Development And They Don’t Even Know It
    Alright, let’s talk about these so-called “vibe coders.” Yeah, the ones out here opening ChatGPT, typing in “make me a full-stack app with auth and dark mode,” and calling themselves developers. No, bro. You didn’t build anything. You summoned a glorified autocomplete and watched it vomit out some Frankenstein code. And now you’re walking around like you cracked the goddamn Matrix? Give me a break. You think you’re coding because you got something working on localhost? Please. You didn’t learn jack. You don’t know what async even means. You can’t debug your own stack to save your life.

    What are the best practices for error handling in C# APIs?
    Introduction Handling errors in a C# API is a crucial aspect of designing robust and user-friendly applications. When errors occur, developers face a decision: should they return error responses immediately or accumulate multiple errors before sending back a response? This article explores the pros and cons of each approach, particularly in the context of using HttpResponseException and ensures best practices are followed. Error Handling Approaches When assessing how to manage API errors, two common approaches emerge: Immediate Response with HttpResponseException Accumulating Errors and Returning them as a List Immediate Response with HttpResponseException In the first approach, the API throws an HttpResponseException as soon as it encounters an error.

    5 developer tools to really step up your workflow
    Here's some few developer tools I've used quite a lot these past few months that has made my workflow way more fast & smooth. Most people choose the git cli over GitHub Desktop. TUI (Terminal UI), so you can easily add changes, make commits, deal with branches, revert & rollbacks, etc. And if you have a server running Git (server with TTY - no GUI), you can easily set lazygit up and use it on the go. Checkout lazygit github for some more idea Similar to lazygit, a TUI manager for docker. After using VScode for years now, I tried using Neovim. If you've heard about Vim, it is notorious for being overly complicated for no reason. write, quit, copy, paste. macros. If you wanna test out vim, would recommend Vim Tutor tool While this is not technically a developer tool, anybody can use it. After jumping from one note to google docs to Notion, I settled into obsidian. Its free, has amazing plugin support, and you get this graph of all the notes you have, that's really cool to watch. Tmux is a "Terminal Multiplexer", so suppose you have ssh-ed into a machine, and want to run two foreground process. How do you do that, both in the same terminal? pseudo terminal". That's just one example. Then switch between these terminals with keybindings, which you can customize. Which one of these do you already use? or suggest more under-rated tools in your arsenal.  ( 4 min )

    ❌ Top 10 Common Mistakes in Writing Scripts
    ❌ Top 10 Common Mistakes in Writing Scripts Using fixed paths, IPs, or credentials inside the script. ✅ Use variables or config files instead. Assuming user input or arguments are always correct. ✅ Always check for type, format, and range. Ignoring exceptions or command failures. ✅ Use try/catch, if [ $? -ne 0 ], or similar. Leaving behind unused logs, temp data, or cache. ✅ Add cleanup functions or use trap in shell scripts. Continuing the script even when a step fails. ✅ Always check exit codes before moving forward. Using vague variable or function names (x, temp, data1). ✅ Use descriptive and consistent naming. Forgetting loop conditions or exit criteria. ✅ Always define clear limits and break conditions. No comments, no usage instructions. ✅ Add inline comments and a help section (--help flag). Writing credentials directly in the code. ✅ Use environment variables or secure vaults. Running scripts directly in production without testing. ✅ Always test in a sandbox or staging environment first.  ( 3 min )

    Multiple Django apps on same port
    Introduction The focus of this article is to run multiple services on a single port, such as hosting two websites on port 80 and port 443. As we all know from the facts that in a system there are total 65536 ports that is from 0 - 65535 ports that are being used, out of this many are system reserved ports and only small amount of ports are available on which we can expose services. Such as port 80 for HTTP, 443 for HTTPS, 22 for SSH , 3389 for RDP and so on. By default every system has at least 2 network cards, one is the loopback or the localhost network card (127.0.0.1), and another one would be either WiFi or the LAN network card (192.168.1.1).

    How to Resolve Operand Type Clash While Backloading SQL Data?
    Introduction When backloading data from a SQL Server table into a DB2 table, you might encounter errors related to null date columns. A common issue is the error message: "Operand type clash: int is incompatible with date". This happens when the data types between the source and destination databases don’t align properly, especially for nullable date columns like ACTUAL_CLOSED. In this article, we'll explore the reasons for this issue and provide effective solutions. Understanding the Issue Why Does the Operand Type Clash Occur? The operand type clash error occurs because SQL Server treats a null date value in certain contexts as an integer zero (0). When this zero gets transferred to DB2, it creates a type inconsistency since DB2 expects an actual date value, not an integer. The use of te…  ( 5 min )

    Catching Secrets Early: A Lightweight Build-Time Tripwire for Vite
    Ever pushed an API key to production? Don’t lie—we’ve all done it. Here’s how to make sure it never happens again, using a 10-line Vite plugin. Secrets don’t belong in your codebase. Not in a commit, not in a PR, and definitely not in production. And yet, it happens—a quick console.log() with an API key, a test token dropped into a config file, a placeholder password that never gets removed. Days later? Still there. Weeks? Maybe it even gets pushed to production. I've heard more than one story of dev teams scanning older, inherited codebases—only to find hardcoded API keys sitting in plain text.

    Compatibility Testing in Software: The Blind Spot in Load Testing
    Introduction As someone with nearly twenty years of experience, I've helped teams understand how their systems perform under pressure. I can tell you this: most load tests don’t fail because there aren’t enough users. And one of the biggest blind spots? Compatibility. You can run a well-designed test, simulate 10,000 users, and hit all your APIs. But you might still miss that your front-end has issues on Safari. Or, your mobile users can’t finish the checkout process. This isn’t just about performance. It’s also a compatibility problem. When you add more users, this issue becomes a performance problem. In the early days of testing, compatibility was about making sure your layout didn’t break in Netscape. As applications changed to single-page apps, mobile-first designs, and multi-device…  ( 6 min )

The following is a workaround for that limitation. String Definitions: 'this is a string' "this is a string" or echo 'this line prints a {$var}'; String concatenation uses a . rather than a + in PHP.

In this post, we’ll take a smarter approach and cover: Setting up Serilog for structured logging in .NET Logging exceptions using source generators Outputting request payloads as structured JSON Masking sensitive data to stay compliant (GDPR, etc.) Enriching logs with contextual information like OrderId Let’s dive in. dotnet add package Serilog.AspNetCore dotnet add package Serilog.Sinks.Console We’ll use the console sink for simplicity because it works out of the box, doesn’t require any extra setup, and still gives us structured…  ( 7 min )
    Inside the Mind of a Cyber Criminal: How Scammers Think and Adapt
    Laura Kankaala, Head of Threat Intelligence, F-Secure Cyber criminals have made scamming a trillion-dollar business. As technology and the internet evolve, so do scams, making them the biggest threat consumers face every time they go online or use their phone. While organizations have been trying to keep up with scammers by employing different types of cybersecurity approaches and frameworks, that same focus has been missing in consumer cybersecurity - until now. The cybersecurity industry often focuses on specific instances of scams, like someone pretending to be Brad Pitt on a dating app, or a user accidentally clicking on a malicious social media ad. We also seem to focus a lot on the psychological aspects of a scam, like certain manipulation tricks that are employed. But putting too mu…  ( 5 min )
    The Hidden Costs of Poor Website Performance: A Business Impact Analysis
    Your website takes 8 seconds to load. In those 8 seconds, half your visitors just left. They're now on your competitor's site, credit card in hand. This isn't a horror story—it's happening to businesses every day. Poor website performance isn't just an IT problem; it's a profit killer that most companies don't see coming until it's too late. Let's uncover the real cost of a slow website and why fixing it might be the best investment you make this year. Think about the last time you waited for a slow website. Did you stick around? Probably not. Your customers won't either. Here's what happens in the first few seconds: 0-1 second: "Great, this site works!" 1-3 seconds: "Hmm, this is taking a while..." 3-5 seconds: "Is something wrong?" 5+ seconds: "I'm out of here." Research shows that 53% o…  ( 6 min )
    Go & AES-GCM: A Security Deep Dive
    Understanding AES-GCM Nonces. A Go Security Deep Dive. Once, while working on a project to upskill a bit, I came across countless resources recommending GCM (Galois/Counter Mode) for encrypting data in Go. Many snippets I found looked similar to this one: package main import ( "crypto/aes" "crypto/cipher" "crypto/rand" "fmt" "io" ) func main() { key := []byte("verysecretkey123") // Never hardcode keys in real life! plaintext := []byte("This is the data to encrypt") block, _ := aes.NewCipher(key) aesgcm, _ := cipher.NewGCM(block) nonce := make([]byte, aesgcm.NonceSize()) if _, err := io.ReadFull(rand.Reader, nonce); err != nil { panic(err.Error()) } ciphertext := aesgcm.Seal(nil, nonce, plaintext, nil) fmt.Printf("%x\n", …  ( 6 min )
    A Professional Looking API
    Your OpenAPI spec is the contract that defines how consumers interact with your API. It powers visual tools that help developers understand, test, and integrate with your endpoints. This spec powers visual tools that help developers understand, test, and integrate with your API. While Swagger UI has been the go-to for years, modern alternatives like Scalar are raising the bar with cleaner UX, better search, and more intuitive navigation. For this post, we’ll be using Scalar to showcase how a well-designed OpenAPI spec gives your API a professional, developer-friendly front. 💡 Hint: Starting in .NET 9, there’s a built-in way to generate the OpenAPI spec using builder.Services.AddOpenApi(). However, as of now, it does not support XML comments, which are essential for rich and descriptive do…  ( 5 min )
    Grok 3 API - Reasoning Tokens are Counted Differently
    I've learned it the hard way... If you use the recently released Grok-3 Mini reasoning model (which is great by the way) you might have your token usage reported wrong... While both OpenAI and xAI report reasoning usage in usage.completion_tokens_details.reasoning_tokens field: OpenAI includes reasoning tokens in usage.completion_tokens xAI doesn't include Hence for OpenAI (and according to my tests for Deepseek R1) in order to get the total tokens you can use the old good completion_tokens field. With xAI you need to add up the 2 values to get the right totals (and get you cost estimations correct). Neither litellm nor AG2 (out of recently used LLM libs) adjust the reported usage for that Grok's quirk. Grok API provides a compatible OpenAI endpoint. For reasoning models the didn't invent the wheel and use the standard reasoning_effort parameter just like OpenAI does with its' o1/o3/o4 models. Yet for some reasons xAI decided to deviate from OpenAI's approach to reasoning tokens accounting. That's unfortunate this inconsistency got into prod API from xAI.  ( 3 min )

    SDK-Driven Development: A Litmus Test for Good Software Design
    This-driven development, that-driven development, and now you should bother with this other thing? I am only half-serious. You should not. Yet you might still want to consider it as a litmus test for your projects. I am not saying that you should use Software Development Kits (SDKs) for development. We all do. Rather, I am asking you to think of your codebase and product as an SDK or part of it. But first, what is all this XYZ-driven development? XYZ simply refers to the guiding principle or artifact that drives the development process. Mind you, this is not necessarily a methodology like "Agile" or "Waterfall", which drive the organization of the development process. I like to think of this distinction as follows: You gather all the developers in a room and organize them to work on a proj…  ( 6 min )
    Why Developers Still Choose Native Mobile Apps in a Cross-Platform World
    Ever tried using a mobile app that felt... off? Maybe the buttons didn’t respond quite right, or it lagged at the worst moment, like when you were about to hit "confirm" on a payment. Chances are, that app wasn’t built natively. In today’s development world, there’s a lot of noise around frameworks that promise to “build once, run everywhere.” Sounds great, right? But despite the rise of cross-platform tools, there’s a quiet but steady group of developers and companies who still pick native mobile app development, and they’ve got good reasons. Let’s dive into why that choice still makes sense in 2025.

    How to Reference Two Dynamic Variables in Helm Templates?
    When creating Helm templates, referencing dynamic values can sometimes be tricky. In your case, you want to access two variables dynamically to retrieve a specific value from your values.yaml file based on the keys defined. ### Understanding the Problem In the provided Helm template, you're trying to access a nested dictionary where both keys depend on dynamic values. Given the owners structure in values.yaml, you want to be able to reference the correct owner based on the dynamic $data_access.name. It's essential to correctly format the reference so that Helm understands which variable to use when fetching the value. ### The Helm Template Structure Here's your original template code for quick reference: {{ $owners := $valuesDict.owners }} {{ $ownerci := $owners.$data_access.name.ci }} #Ge…  ( 4 min )

    Understanding Hoisting in JavaScript
    Hoisting is a fundamental concept in JavaScript that often leads to confusion, especially for those new to the language. Understanding how hoisting works can help you write cleaner and more predictable code. This article explains what hoisting is, how it works, and the differences in behavior between various types of declarations. Hoisting is JavaScript’s default behavior of moving declarations to the top of their scope before code execution. This means that variables and functions can be referenced before they are declared in the code. It is important to note that only declarations are hoisted, not initializations. var Variables declared with var are hoisted and initialized with undefined. Consider the following example: console.log(a); // undefined var a = 10; Internally, this is inte…  ( 4 min )
    Mastering Flask Blueprints: The First Step to Scalable Web Apps
    As I started learning Flask, I was building simple apps just to understand the basics and get comfortable with it. Once I felt a bit more confident, I decided to start a project, a site monitoring tool. Since I knew the project would grow and include more functionality, I realized that things should be organized better. That’s when I came across Flask Blueprints. A Blueprint is a modular way to organize code and routes into separate components. Today, I set up my first Blueprint in Flask and here’s how it went. blueprint-example/ ├── run.py └── app/ └── routes.py └── __init__.py └── templates/ └── index.html from flask import Blueprint,render_template #creating a flask blueprint called 'main_route' main_route=Blueprint('main_route',__name__) #define a route on this blueprint @main_route.route('/') def blue_example(): return render_template('index.html') from flask import Flask app=Flask(__name__) def blue_example(): from .routes import main_route app.register_blueprint(main_route)#registering my blueprint to my flask app instance return app from app import blue_example app=blue_example()#Calling a function to get flask app instance if __name__ == '__main__': app.run(debug=True) #run the app in debug mode I basically had an idea of how this works because I had learned about MVC (Model, View, and Controller) in Java. The working process of both is quite similar, so I was able to grasp it a bit quicker. Here are a few things I found helpful about using Blueprints: It's a clean way to split the code logically. For example, separating routes and the dashboard into components makes the structure much easier to work with. It's much easier to manage as the app grows and more features are added. It makes the project more organized and scalable, which is especially useful when working in teams or revisiting the project later.  ( 3 min )

    De MediatR para Mediator: uma migração mais leve e performática
    *Dando continuidade à série sobre bibliotecas .NET que deixaram de ser open source e gratuitas, neste artigo apresento uma alternativa ao MediatR e explico por que ela pode representar uma migração mais leve em termos de estrutura e performance. Desde que foi anunciado que o MediatR passará a adotar um modelo de licenciamento pago — mesmo que isso ainda leve algum tempo e a versão atual permaneça gratuita — nós, desenvolvedores, começamos a buscar alternativas próximas do que já conhecemos ou, em alguns casos, optamos por implementações próprias, como abordado no artigo anterior sobre o AutoMapper.

    How to Generate Large Random Numbers in C with rand()?
    Generating large random numbers is a common requirement in programming, especially in applications requiring strong randomness. The standard rand() function in C generates pseudo-random numbers, which often fall short in range and size for many applications. In particular, generating unsigned long long random numbers can be challenging, especially if you find that the outputs of rand() are not sufficiently large and they often exceed certain thresholds. Why the Standard rand() Does Not Meet Your Needs The rand() function is designed for simplicity and it typically returns a value in the range from 0 to RAND_MAX, which is defined in stdlib.h. The maximum value returned by rand() is often just 32767, making it unsuitable for generating large random numbers like those represented by an unsign…  ( 5 min )

    The Simple Math of why big tech needs AI
    I worked for a FAANG company for a bit, and one thing that surprised me was just how many tasks were manual. How noticeably patchy the tooling and automation coverage was. But also very obviously their tooling and automation was state of the art and much more sophisticated than small tech. But I think there's basic math at play. If I work at a small company and have 100 things, and 50% are automated, then I need say 50 engineers to handle the workload. But if I work at big tech, and there are 100,000 things, and 75% are automated, then I need 25,000 engineers to handle the workload. There's also the algorithm optimization. While I think alogrithmic optimizations will trickle down, and that's good. For (AlphaEvolve)[https://news.ycombinator.com/item?id=43985489] to have a 1% speedup in most small to medium size businesses. Fine, but that's not worth spending a lot of time on. But for AlphaEvolve to have a 1% speedup at google? May save millions of dollars. The point of which is to say, there's probably lots of ways that this will trickle down to every day users, and software engineers across the board may see more and more of their tasks automated, but a continuous truism in the industry is that what works for big tech often doesn't work for you medium-sized MSP. This might explain the difference between why Google says that AI can write 30% of it's code, and medium sized business struggle to get it to work. There's just a lot less boilerplate to right at medium sized businesses. At google, being able to automatically upgrade a node.js dependency may literally impact thousands of microservices, saving thousands of engineering hours. At your company it might save a few hours, if it doesn't take longer than that to get it going in the first place.  ( 3 min )

    Understanding the Differences Between HTTP/1.1 and HTTP/2
    As the web continues to evolve, the need for faster, more efficient communication between browsers and servers has driven the development of modern protocols. HTTP/1.1, introduced in 1997, served the web for nearly two decades. But with increasing demand for speed, efficiency, and performance, HTTP/2 emerged as a much-needed upgrade. Let’s explore the major differences between these two protocols in a clear, visual, and easy-to-understand way. HTTP/1.1 is a text-based protocol that works on a request-response model. While it has served its purpose for years, it has several limitations: Sequential Requests: Only one request is allowed per TCP connection at a time, leading to blocking. Multiple Connections: To fetch multiple resources, browsers open multiple TCP connections, which increases …  ( 3 min )

    Query MongoDB Like a Human with ScoutDB
    🗥️ So I was casually doomscrolling X (yes, again)... when I stumbled upon a post by DEV Community that made my brain short-circuit: ✨ “ScoutDB turns plain English into MongoDB queries.” Wait, what?! You've got the data questions, but not always the query-fu: "Find all users who joined after Jan 2023 and liked more than 5 posts" Normally, you'd need to hand-craft some MongoDB incantation like: db.users.aggregate([ { $match: { joinDate: { $gte: ISODate("2023-01-01") }, likes: { $gt: 5 } } } ]) But what if you could skip the syntax pain? ScoutDB is like having a friendly AI that: ✅ Understands what you're trying to ask in English explore like a boss You type: Show me all posts with more than 100 likes created in the last 30 days ScoutDB replies with: db.posts.find({ likes: { $gt: 100 }, createdAt: { $gte: new Date(Date.now() - 30*24*60*60*1000) } }) Then maps the results and relationships for you in a visual explorer. No more $lookup headaches. No more crying in JSON.

    Elm’s Type Inference: Crafting Sound Code with Friendly Compiler
    Elm’s type system lets you write clear, correct code without the clutter of explicit type annotations. Its friendly compiler not only infers types automatically but also provides helpful error messages that guide you toward writing sound code. In this post, we'll explore practical examples that highlight how Elm’s type inference and compiler feedback enhance code correctness and simplify your development experience. When coding in Elm, the compiler deduces the types of values based on their usage. This lets you focus on application logic rather than on managing repetitive type declarations. Consider a simple arithmetic function: square x = x * x Since the multiplication operator (*) applies only to numbers, Elm infers that x must be a number. No extra annotations are needed, keeping y…  ( 5 min )
    How to automate email verification with Selenium
    When people create new accounts, it’s normal for you to need a way of contacting them with onboarding information, billing alerts, and more. That’s why having the right email address is so important. However, what if they made a typo when providing the email address? Or they simply want to create an account without any real interest in using the service as intended? In either case you’ll want to verify that they can access the email address they’ve given you. The simplest approach adopted by most is to send a unique link in an email to that address, and have a user click on that link to verify their account. It’s simple, but it works.

    Vibe coders or new coder advice: Scope of work
    Yes, this was written with the help of AI, but hear me out! Most tutorials and videos miss this detail, which is the right scope of work in the context of an AI coding tool (like Cursor, etc.). They might say, "keep it short," but what exactly is that? We've all been in a place where we go down a rabbit hole for hours and lose track. This article will help you get that under control! When you're working with AI in a chat window—like building a new feature in a SaaS multi-tenant app—it’s easy to get lost in the weeds. Should you build the whole thing at once? Go step by step? Here's a practical way to scope your work, avoid rabbit holes, and get the most out of your AI assistant.

    Diary of an Elm Developer
    Every morning I gift myself 90 mins to work on anything I desire. Sometimes I read interesting books (1, 2, 3, 4), other times I learn new skills (5, 6) but most times I work on programming projects. For a long time now those programming projects have been Elm related. What can I say? I simply enjoy using Elm. I've tried to share my knowledge along the way by taking the time to reflect on what I've done and by writing about it from my perspective. On many occasions I just shared the work and put off sharing my thoughts about the work for so long that it became a chore to write about it. Reflecting and writing about my programming selfishly helps me improve my software development skills. Writing in public forces me to think more deeply about what I'm doing and why I'm doing it such that it gives me a richer understanding of my craft. A positive side effect is that what I share could also potentially help others. Though, I try to temper my hubris and not fool myself into thinking that random people on the internet actually care about what I have to say. Given that I sometimes don't share and write about my work as often as I'd like and that I think sharing and writing about my work helps myself and others, I've decided to start a new series on this blog called "Diary of an Elm Developer". It's a way for me to give myself permission to share more frequently about my Elm related excursions in an open and freer format. I'm feeling excited about this new series. Stay tuned! If you're interested in improving your skills with Elm then I invite you to subscribe to my newsletter, Elm with Dwayne. To learn more about it, please read this announcement.  ( 3 min )

    5 Lessons from Neurology That Make Me a Better Software Engineer
    Hello DEV community 👋 My name is Alireza Minagar, and I come from a rather unique background — as a neurologist, researcher, and now a software engineering student. After years of diagnosing complex neurological conditions, I’ve begun exploring how artificial intelligence and software can revolutionize healthcare. Surprisingly, many skills from my medical background translate directly into programming. Here are 5 lessons from neurology that shape how I now think about software engineering: In medicine, we never treat a symptom without understanding its root cause. Debugging works the same way — don’t guess. Investigate. Analyzing EEGs or MRIs is about spotting patterns. Writing efficient code or identifying logical bugs requires the same cognitive muscle. Whether prescribing medication or defining logic in code, tiny errors can lead to serious consequences. Precision builds trust — in both healthcare and software. Medical professionals live by notes. In code, comments, READMEs, and clear commit messages keep everything healthy and maintainable. In both medicine and tech, decisions have real consequences. Transparent, explainable algorithms are just as vital as informed consent. I’m currently learning Python, full-stack engineering, and bioinformatics with the goal of contributing to healthcare-focused AI solutions. Let’s build a world where medical insight and machine logic support — not replace — human care. — Alireza Minagar, MD, MBA, MS LinkedIn: linkedin.com/in/alirezaminagar Medium: medium.com/@aminagar_38889  ( 3 min )

    You're slicing your architecture wrong!
    For the longest time, the "separation of concerns" has been the ultimate guiding principle of software engineering. We thus structure our codebases accordingly: Grouping related files by responsibility; Partitioning logic by technical layers; And sometimes even isolating by programming language.1 Popular architectural patterns such as the Model-View-Controller (MVC) have applied and codified this principle to the point of dogma. Universities, bootcamps, and courses everywhere teach and perpetuate the notion that the MVC architecture is the be-all and end-all of architectural patterns. To be fair, the MVC architecture is indeed often the correct mental model for fathoming any CRUD-heavy application (i.e., virtually 99.9% of web applications2) because it formalizes the flow of data from t…  ( 6 min )

    small thought: Developer Ethics may be a bridge to work with AI tools
    Last year, I intensely started using AI (LLM) tools and caught a terrible wave of sadness and melancholy after 5–6 months of use. For me, the most difficult thing wasn’t that an LLM could write code in general, but the realization that, in fact, it’s not that important. A much more significant abstract question arose: why even write it if everything could change so quickly tomorrow that you wouldn’t even blink? After feeling down and literally being sick of it, and wandering through bookstores, I stumbled upon an interesting book — “The Art of Excellent Products: Enchanting Customers with Premium Brand Experiences” by Riccardo Illy. And this book resonated so deeply that I understood how to resolve (for the time being) the moral dilemma with AI code, when you don’t write the code yourself,…  ( 4 min )
    Sony considers further price rises, as it braces for £500m tariffs impact
    Sony’s eyeing another round of PS5 price hikes after warning that new US tariffs could hit it to the tune of roughly ¥100 billion (£513 million). Despite sitting on three months’ worth of US stock, the console maker is “evaluating” whether to pass those extra costs on to gamers. It’s already bumped the digital PS5 up by £40/€50 across the UK, Europe, Australia and New Zealand this spring, on top of previous—and even steeper—price rises in Japan. To dodge ongoing tariff roulette, Sony exec Hiroki Totoki said shifting some PS5 production to the US “needs to be considered going forward” as an “efficient strategy.” No US price hikes have landed yet, even as rivals like Microsoft and Nintendo tweak their own hardware costs in response to the same trade tangle.  ( 3 min )
    DOOM The Dark Ages on Steam Deck is a "nightmare" even at "low-quality" and in linear levels
    TL;DR: Doom The Dark Ages might be a blast on PC and consoles, but on Steam Deck it’s straight-up “nightmare” territory. Even with XeSS Quality set to low and resolution cranked down to 1280×720 (and later 960×540), SteamDeckHQ could barely eke out 30 FPS in open areas—and those dips into the mid-20s make everything blurry, pixelated and generally unplayable. If you’re eyeing the Deck as your go-to, steer clear—for now at least. Patches might improve performance down the line, but there’s no guarantee. If you want demon-slaying glory without constant frame-rate faceplants, stick to PC, PS5 or Xbox Series X/S.  ( 3 min )
    Another GTA 6 delay could happen as respected insider says there’s “no guarantee” for a May 2026 release
    After getting bumped from late 2025 to May 26, 2026, GTA 6 still isn’t locked in—Bloomberg insider Jason Schreier warns there’s “no guarantee” Rockstar will hit that window. The first delay already sent panic through the industry, with other developers shifting their own launches to dodge the Grand Theft Auto onslaught. While a second slip hasn’t been announced, rival studios and especially PC players are bracing for more slippage—meaning even when consoles finally get the game, the PC port could be pushed way further down the road.  ( 3 min )
    The Voice Of Master Chief Asks Halo Fans To Stand Up For Voice Actors On Strike.
    TL;DR: Steve Downes, the legendary voice of Master Chief, is rallying Halo fans to back the 10-month-long SAG-AFTRA video game voice actors strike. The crux of the dispute? AI voice replication—actors want control over if and how their voices are used, not a blanket ban on AI. Downes (joined by Cortana’s Jen Taylor and veteran Jennifer Hale) stresses, “We’re not against AI, just its misuse,” and urges gamers to make some noise until the “Last, Best, and Final” offer on the table addresses those AI concerns. After other issues found middle ground, this remains the sticking point that could make or break a deal.  ( 3 min )
    Meta is paying freelancers to record their smiles, movements, and small talk - data to train Codec Avatars
    Meta’s new gig: get paid to smile, squat, and chat Meta has quietly kicked off “Project Warhol,” a data-collection effort run through Appen, that pays participants $50 an hour to record facial expressions, body movements (think squats), and even small talk. The goal? To supercharge the realism of its VR avatars for the metaverse—and ultimately make everyone’s digital doppelgänger a lot less robotic. Why now? A make-or-break 2025 for Reality Labs Reality Labs has bled about $60 billion since 2020, and Meta’s calling 2025 its most critical year for VR, avatars, and AI wearables. By crowdsourcing human data, Zuckerberg hopes to finally level up Meta’s metaverse cred and turn those once-mocked cartoon avatars into something you’d actually want hanging out with.  ( 3 min )
    Meet AlphaEvolve, the Google AI that writes its own code—and just saved millions in computing costs
    TL;DR: Google DeepMind’s new AI agent, AlphaEvolve, teams up with Gemini LLMs and an evolutionary test-and-refine loop to invent entire computer algorithms—and it’s already live inside Google’s infrastructure. It’s boosted Borg cluster efficiency by 0.7%, trimmed bits off TPU circuits, and even sped up Gemini model training kernels by 23% (cutting overall training time 1%), all while churning out human-readable code. But AlphaEvolve isn’t just optimizing data centers—it’s smashing math records. Using its gradient-based evolution, it beat Strassen’s 56-year-old 4×4 matrix-multiply record, improved 14 algorithms, and tackled 50+ open problems (nailing or improving 75% of them), including setting a new 11-dimensional “kissing number” high score. With its plug-and-play approach, DeepMind hopes to spin out breakthroughs in material science, drug discovery, and beyond.  ( 3 min )

    RSA Conference 2025: How Agentic AI Is Redefining Trust, Identity, and Access at Scale
    There is a good chance that when you hear "San Francisco," you immediately think of cable cars. These moving national landmarks have been continually operating since 1873. This technology relies on tracks and a robust underlying cable technology, mostly hidden away from the public eye. This made SF the perfect backdrop for conversations about a modern technology that needs tracks and guardrails: agentic AI.  If there was a common thread among the conversations at this year's RSA Conference, it was the emergence of agentic AI as an operational "colleague," not just a tool. This path poses a lot of questions for trust, governance, and identity in security. We are no longer merely integrating AI; we're now onboarding it.

    When the 199,999th COBOL Expert Leaves, Will Your Systems Survive?
    A programming language older than email, older than the internet, and definitely older than most of us writing code today – is still running your bank! Yep, I’m talking about COBOL. It’s been around since 1959, and somehow, it’s still quietly powering over $3 trillion in daily commerce. In fact, it handles 95% of ATM transactions and supports nearly half of the world’s banking systems. The simple answer is : Because it works. And it’s been working for decades. It’s embedded in banking, insurance, government systems – you name it. 200,000 COBOL experts are on the verge of retirement this year, and as per Gartner, almost 70% of enterprises don’t train new devs in COBOL anymore. We’re heading for a major skills gap, and its consequences are in the foreseeable future. Well, things get messy. …  ( 5 min )
    Golang - How to do Benchmarking
    Performance matters — especially when dealing with large-scale systems or performance-critical code. Go (Golang) provides first-class support for benchmarking via the testing package. This article walks you through the fundamentals of benchmarking in Go: what it is, why it's important, and how to run benchmarks to compare multiple functions. Benchmarking is the process of measuring how efficiently a piece of code executes. In Go, this typically involves determining how long a function takes to run, how many resources it uses, or how well it scales under load. Benchmarking is different from testing — it doesn’t check if your code is correct but it checks how well it performs. Benchmarking is useful when you want to: Compare different implementations of the same logic (e.g., using + vs strin…  ( 4 min )
    Building a Real-Time Market Data Aggregator with Kafka and MongoDB
    It starts the same way every time: an RSS feed, a CSV dump, a dashboard wired together with hope and duct tape. Maybe the data’s late. Maybe the moving average lags just enough to miss the signal. Or maybe it’s just another system straining under the weight of “real-time” without the architecture to back it up. In this tutorial, we’ll build something better. Using Spring Kafka, we’ll stream simulated live stock data into a Kafka topic. From there, Kafka Streams will compute the Relative Strength Index (RSI) on the fly, and we’ll persist it to MongoDB using Spring Data MongoDB. On the historical side, we’ll use MongoDB’s aggregation framework to calculate and analyze simple and exponential moving averages (SMA and EMA) using the MongoDB aggregation pipeline—no third-party data warehouse req…  ( 24 min )

    Demystifying RAG 🔍: Retrieval-Augmented Generation Explained
    The term RAG (Retrieval-Augmented Generation) refers to a hybrid AI framework that combines information retrieval (like Googling) with large language models (LLMs) to deliver accurate, context-aware answers. Unlike traditional LLMs that generate responses based solely on pre-trained knowledge, RAG grounds its answers in real-time, external data, minimizing errors and hallucinations. Why RAG Matters LLMs like GPT-4 excel at generating text but face limitations: Static knowledge: They can’t access up-to-date or domain-specific data. Hallucinations: They may invent plausible-sounding but incorrect facts. RAG solves this by dynamically retrieving relevant information before generating a response, ensuring answers are factual, current, and contextually grounded.

    Visualization Beyond Aesthetics
    In today’s data-driven world, we’re surrounded by slick dashboards, colorful graphs, and eye-catching infographics. Whether you’re scrolling through LinkedIn or sitting in a boardroom, chances are you’ve seen a chart that looks great—but does it actually help you understand the data? Data visualization is often praised for its aesthetic appeal, but effective visualization is about much more than making data look pretty. At its core, it’s about making complex information clear, truthful, and actionable. As Edward Tufte, a pioneer in the field, once said: “Graphical excellence consists of complex ideas communicated with clarity, precision, and efficiency.” — The Visual Display of Quantitative Information Let’s dive into why visualization should go beyond just the aesthetics—and how designer…  ( 5 min )

I will occasionally post articles on distributed systems if I come across topics that should be added. Your engagement and feedback have been incredibly motivating, and I'm excited to announce my next series on Dev.to! Starting this Sunday, I will be launching a new series focused on system design, inspired by the book Righting Software by Juval Löwy. This book is divided into two parts: system design and project design. My series will concentrate on the system design aspect. Weekly Articles: Every Sunday, I will release a new article that delves into various system design techniques and principles. We will dive into the real world examples. Comprehensive Coverage: While the book will serve as a reference, it is not necessary to have it. My articles will cover almost everything you need to know. Practical Insights: You will learn an amazing system design technique that I personally find invaluable. I use it in all my projects, whether they are small or large, professional or personal. Hands on: I will also try to deliver some hands on projects where people following will dive deeper into the concepts. I had the privilege of attending a System Design cohort led by Jeff Doolittle. The insights and knowledge I gained from that experience, combined with my day-to-day work on real-life systems, will be reflected in this series. I am committed to delivering the most valuable content, drawing from both the book and my practical experiences. Stay tuned, and don't forget to follow me to get the latest updates! Thank you once again for your support. Let's embark on this exciting journey of mastering system design together!  ( 3 min )
    Gatekeepers Limit Continuous Delivery’s Benefits
    Having too few people with deployment authority reduces software delivery performance. Developer experience and burnout may have put platform engineering in the spotlight, but focusing on continuous delivery will likely improve developer experience (DevEx) the most at your organization. There is, however, a speed bump ahead for those automating their deployment pipeline: deployment gatekeepers. If you don’t increase the number of people with deployment authority, you’ll miss many of the benefits of continuous delivery. A single deployment gatekeeper will lower your chances of getting a return on your investment within the first 100 days and permanently limit your software delivery performance. So, how does this happen? There is a dramatic shift in your work system once you automate your de…  ( 5 min )

    How YouTube Might Track “Most Replayed” Parts of a Video — in Ruby on Rails
    Have you ever noticed the spiky graph above the YouTube timeline showing "Most Replayed" sections? In this post, we’ll build a simplified version of that system using Ruby on Rails — to track, store, and visualize which parts of a video are being re-watched the most. We'll use two tables: videos – to store video metadata video_interactions – to log when a user scrubs, replays, or pauses at a specific second videos # db/migrate/20250515120000_create_videos.rb class CreateVideos < ActiveRecord::Migration[7.0] def change create_table :videos do |t| t.string :title t.integer :duration_seconds t.references :uploaded_by, foreign_key: { to_table: :users } t.timestamps end end end video_interactions # db/migrate/20250515120500_create_video_interactio…  ( 4 min )
    How to Get Method Names with Type Parameters in Kotlin?
    In Kotlin, it's convenient to retrieve the names of methods for logging or debugging purposes, especially when leveraging IDE refactoring features. This article addresses the common issue developers encounter when trying to obtain the name of a method that has type parameters, and provides clear solutions for achieving this goal while maintaining code clarity. Understanding the Problem When attempting to retrieve the name of a method using the reference operator (::), developers often succeed with methods that do not have type parameters. The syntax this::foo.name works seamlessly for simple methods. Example of a Basic Method Take a look at the following class that includes a method without type parameters: class A { fun foo() { /* implementation */ } fun bar() { val fooNa…  ( 4 min )
    The SEO Game Has Changed
    If ChatGPT Can't Find You, Do You Even Exist? The rise of AI-powered tools like ChatGPT, Perplexity, and Google's new AI search is reshaping how we think about content discovery. Traditional SEO (Search Engine Optimization) is no longer enough. Today, it's just as important to consider how your content surfaces in AI-generated responses, not just in Google's search results. Being on page two of Google used to be a death sentence. Now, it's worse: if AI tools can't find or quote you, you're invisible. GEO builds on traditional SEO, but the game has changed: Instead of asking "How do I rank on page one?", ask "How do I become a trusted source AI will quote?"

    Hit a Wall During Upgrade? This Guide Walks You Through Upgrading DolphinScheduler from 2.0 to 3.0
    Due to project requirements, we needed the data quality module, which offers excellent data quality monitoring capabilities for data warehouses. Therefore, we decided to upgrade from the existing 2.0 version to 3.0 or above. We tested both versions 3.0.1 and 3.1.1 by running identical task scheduling operations such as pausing tasks. In the end, we chose version 3.0.1. Reasons: When testing SQL tasks in 3.1.1, launching hundreds of SQL tasks simultaneously caused errors that prevented many tasks from running properly. After consulting the community experts, it was confirmed to be a bug in DolphinScheduler. Although this issue occasionally appears in 3.0.1 as well, it is much less frequent. Versions above DS 3.0.1 use a newer version of the ZooKeeper dependency. The driver version is 3.8.…  ( 15 min )
    What is chatbot?
    A chatbot (originally chatterbot)[1] is a software application or web interface designed to have textual or spoken conversations.[2][3][4] Modern chatbots are typically online and use generative artificial intelligence systems that are capable of maintaining a conversation with a user in natural language and simulating the way a human would behave as a conversational partner. Such chatbots often use deep learning and natural language processing, but simpler chatbots have existed for decades. Although chatbots have existed since the late 1960s, the field gained widespread attention in the early 2020s due to the popularity of OpenAI's ChatGPT,[5][6] followed by alternatives such as Microsoft's Copilot, DeepSeek and Google's Gemini.[7] Such examples reflect the recent practice of basing such…  ( 3 min )

    Log me Baby
    A couple of months ago I joined CloudRift, tagging along my long time peer Dmitry in his new venture. One of the first things that came up was setting up log aggregation — something many projects start without, but quickly realize they need after spinning up more than one server. It should be a mundane task after having done this a few times, but yet again, there is a twist and something new to discover. I pull out my usual cards and start with ELK, since even though there are serious contenders out there, I still find Kibana unbeatable, and most people love it. CloudRift deploys its agents on pools of nodes which in turn communicate with an orchestrator that acts as a centralized resource broker. While in most scenarios log forwarding is handled by a daemon, like filebeat or fluentd, with…  ( 11 min )

    How Server Management Practices Impact Website Performance: An SEO Perspective
    In the world of digital marketing and SEO, we often focus heavily on content, backlinks, and keywords. However, one often overlooked factor is server management—a technical area that has a surprisingly significant impact on site performance and rankings. Google considers page speed and uptime when ranking websites. If your site takes too long to load or frequently goes down, your rankings can be negatively affected. Some of the key server-side factors that influence SEO include: Server response time (TTFB) Downtime or hosting issues Poor load balancing or caching strategies Misconfigured SSL or redirects These aren't typically in an SEO’s toolkit, but they have direct consequences. Recently, while working with a client whose site was experiencing random slowdowns, we discovered the issue was rooted in unmanaged server processes consuming too many resources. After a server audit and implementing best practices (including log rotation, performance monitoring, and scaling strategies), we saw a measurable improvement in Core Web Vitals and a 12% increase in organic traffic in 3 weeks. For those unfamiliar with these tasks, there are server management teams that handle these backend operations seamlessly, allowing businesses to focus on growth while maintaining technical health. SEO isn't just about keywords and content. If you're ignoring server-side optimization, you're leaving potential growth on the table. Collaborating with developers and sysadmins—or understanding their pain points—can give you a competitive edge in search results. Have you ever encountered server issues that affected your SEO performance? Let's discuss in the comments.  ( 3 min )

    HAS-A vs IS-A in OOP C#
    In Object-Oriented Programming (OOP), HAS-A and IS-A relationships are fundamental concepts used to describe how classes and objects relate to each other. While these apply to many OOP languages like Java or C#, the principles are universal. IS-A Relationship (Inheritance) Represents: A subtype relationship (child → parent) Mechanism: Achieved through inheritance. Implies: The derived class is a type of the base class. Usage: Use when there’s a clear hierarchical relationship. public class Animal { public void Eat() => Console.WriteLine("Eating..."); } public class Dog : Animal { public void Bark() => Console.WriteLine("Barking..."); } // Usage Dog dog = new Dog(); dog.Eat(); // Inherited dog.Bark(); // Dog-specific Dog IS-A Animal. HAS-A Relationship (Composition) Represents: A class containing references to other classes as members. Mechanism: Achieved through composition (member variables). Implies: A class has a reference to another class. Usage: Use when one object uses another. public class Engine { public void Start() => Console.WriteLine("Engine starting..."); } public class Car { private Engine engine = new Engine(); public void StartCar() { engine.Start(); Console.WriteLine("Car started."); } } // Usage Car car = new Car(); car.StartCar(); Car HAS-A Engine. Aspect IS-A HAS-A Meaning Inheritance (child ← parent) Composition (class contains) Implementation class B : A {} class A { B b; } Example Dog : Animal Car has Engine Use Case Reuse behavior via inheritance Delegate tasks via composition Polymorphism Supported Not directly Prefer composition (HAS-A) over inheritance (IS-A) when possible (favor delegation for flexibility). Use IS-A only when the subclass truly fulfills the contract of the superclass (Liskov Substitution Principle).  ( 3 min )
    Cloudflare Tunnel for Home Assistant
    I continue to take care of my Home Assistant. This week, I replaced my original setup with Cloudflare Tunnel. My usage of Home Assistant required external access from the beginning. I achieved it in two steps: I created a subdomain of frankel.ch, which pointed to my router's external IP. On my router, I opened a dedicated port. In turn, the router forwarded requests to my HA. The next action was to secure connections via an SSL certificate. I initially aimed for mTLS, but I couldn't achieve it because the iPhone HA application doesn't support it. However, encrypted communication to my server was a hard requirement. The good news is that the times when SSL certificates were a luxury feature are gone.

    Make C++ a better place #3: D as an alternative
    The D programming language, commonly known as DLang, offered a fresh perspective on system-level programming by blending familiar features of C++ with modern mechanisms to enhance code safety, simplicity, and performance. Created by Walter Bright, it is meant to be a viable alternative to C++ for developers seeking to improve productivity and code safety while maintaining the low-level control that C++ offers. DLang is a general-purpose, statically typed programming language with many parallels to C++. Like C++, it supports object-oriented programming, manual memory management and systems programming. However, DLang builds on these fundamentals by introducing features that mitigate some of the complexities and pitfalls of C++, like garbage collection.

    .NET Learning Notes: Test Your Code(Unit Test)
    Unit Test Unit testing is a type of software testing where individual units or components of a software are tested in isolation. The purpose is to validate that each unit of the software performs as expected. A unit is the smallest testable part of an application, such as a function, method, or class. Arrange-Act-Assert(AAA) is a simple and effective pattern for writing clear and structured unit tests: Arrange-set up the necessary objects and state, Act-perfom the action you want to test, Assert-verify that the action produced the expected result. Commenting the AAA phases is recommended, especially during learning, in shared codebases, or for more complex test cases. It improves readability, consistency, and maintainability of tests.

    🎢 Scroll-Linked Animations in CSS Are Here — And They’re Kinda Awesome
    Ever wanted to animate something on scroll without reaching for JavaScript? Well, good news: modern CSS has a new trick up its sleeve called animation-timeline: scroll() — and it’s surprisingly powerful. Let me show you what it is, how it works, and why you might want to use it in your next project. ⸻ 🌀 What Is animation-timeline: scroll()? Traditionally, CSS animations run on a timeline based on time (seconds, milliseconds, etc.). But with this new feature, the animation is synced to the scroll position of an element. That means: the more you scroll, the further along the animation progresses — and when you stop scrolling, the animation pauses too. No JavaScript. No ScrollTrigger. Just clean CSS. ⸻ ✏️ A Simple Example Here’s a quick setup I made: <div id="square"…  ( 5 min )

    The Art of Writing Maintainable React Components
    The Art of Clean React: Principles for Maintainable Components 🎨 Single Responsibility Principle (SRP): One Job, One Component 🎯 Just like functions should do one thing well, so should your components. A component should ideally have a single, well-defined purpose. If a component starts handling too many responsibilities (managing multiple unrelated states, fetching diverse data, rendering complex unrelated UI), it becomes harder to reason about and more prone to breaking.   Bad Example (Multiple Responsibilities): Imagine a component that fetches user data and handles form submissions for a new address. Good Example (Separated Responsibilities): Break this down into two components: one responsible for fetching and displaying user data (UserProfile), and another for handling the address…  ( 5 min )

    Why the alt Attribute Matters?
    Images are an essential part of the web. They inform, engage, and enhance the overall user experience. But what happens when an image fails to load, or when a user cannot see it? That’s where the humble alt attribute of the tag comes into play, serving as a vital link between visual content and universal accessibility. The alt attribute in HTML provides alternative text for an image. This text is displayed if the image cannot load. More importantly, it is read aloud by screen readers, helping visually impaired users understand the content and context of images. alt Attribute Important? The alt attribute serves several important purposes, Visually impaired users rely on screen readers to navigate the web.

    When a password manager forgot how to manage, I brought the drama
    Some stories begin with a bug report. Mine begins with Bitwarden... and ends with a stand-up comedy set on GitHub. I just wanted to register. That’s all. No expectations. No edge cases. Just one humble email and a password. But when the UX said “no,” I said, “fine — I’ll write a one-act play instead.” So here it is: A theatre of sarcasm, screenshots, a dramatic banner, and a not-so-silent scream of a user who had some free time and a working brain. 🎭 Link to the GitHub drama: https://github.com/MenstaDay/bitwarden-registration-theatre No bitterness.

    My opinion about Rails 8
    I wrote this post originally on my website : https://alsohelp.com/blog/rails-8-opinion If you want to see the final app, just ask me ;) Here is the article below : Here is my 2 cents after 10 years with Rails and 6 months with Rails 8 in production. The most surprising part is probably that they are proud of removing parts in a brand new version. I view it as an excellent sign of maturity. The subtitle of Rails 8 is "no PaaS required", but they could have also said : "No React required", "No Redis required", and so on. What a relief. Any shiny new framework is proud about "what's new under the sun", not "what's deleted to simplify devs life". The first excellent part is what didn't move.

    🌐 Computer Networks: The Backbone of the Internet
    What Are Computer Networks? A computer network is a group of interconnected devices that can communicate and share resources. Think of it as the digital nervous system that connects computers, phones, servers, and more—allowing data to flow like information highways. Used in homes, schools, and offices. Connects devices in a small area. Covers a large geographic area. The Internet is the biggest WAN. Covers a city or a large campus. Larger than LAN but smaller than WAN. Your Bluetooth devices form a PAN—like your phone and earbuds. Router: Directs data packets between networks. Switch: Connects multiple devices in a LAN. Modem: Connects to your ISP and provides internet access. Access Point: Enables wireless devices to connect to the network. Server & Client: Server provides, client consumes services/data. Physical Data Link Network Transport Session Presentation Application Each layer has a specific role—from moving bits to enabling web apps. More practical and used in real-world networking: Link Internet Transport Application HTTP/HTTPS – Web browsing FTP/SFTP – File transfers SMTP/IMAP/POP3 – Email TCP/UDP – Data transport IP – Routing and addressing DNS – Resolves domain names to IPs Whether you're streaming Netflix, sending a meme, or backing up your files to the cloud—computer networks make it all happen. They're the silent enablers of our digital lives. 🧠 Fun Fact: The first message ever sent over the ARPANET (the Internet’s ancestor) was "LO"—they meant to type "LOGIN" but the system crashed! Stay tuned, stay connected, and maybe ping your friend instead of ghosting them. Tools That Help: Wireshark, Cisco Packet Tracer, Netcat, Nmap, and a whole lot of curiosity.  ( 3 min )

    Callbacks in JavaScript
    What is a Callback? A callback is a function passed into another function, to be called later when something happens or a task is finished. Analogy: Imagine you order food and give the restaurant your phone number so they can call you when your food is ready. Your phone number is the callback. JavaScript is single-threaded and often needs to wait for things (like loading data or waiting for a user action). Instead of stopping everything, it uses callbacks to say, “Do this later, when the waiting is done.” function doSomethingLater(callback) { console.log("Doing something..."); callback(); } function sayHello() { console.log("Hello, I'm the callback!"); } doSomethingLater(sayHello); Output: Doing something... Hello, I'm the callback! doSomethingLater(function() { console.log("This is an inline callback!"); }); setTimeout and setInterval setTimeout(function() { console.log("This runs after 2 seconds"); }, 2000); Event Listeners button.addEventListener('click', function() { console.log("Button clicked!"); }); Fetching Data (with Promises, but still uses callbacks) fetch('https://api.example.com/data') .then(function(response) { return response.json(); }) .then(function(data) { console.log(data); }); Callbacks are not always asynchronous. Some callbacks are called right away. Callbacks are just functions. There’s nothing special about them except how they’re used. Callback Cheat Sheet Definition: A callback is a function you pass to another function to be called later. Basic Example: function callback() { ... } someFunction(callback); Anonymous Example: someFunction(function() { ... }); Typical Uses: setTimeout, setInterval Event handling (like clicks) Fetching data from APIs Key Point: Callbacks help JavaScript handle tasks that take time, so your code can keep running without waiting.  ( 3 min )

    How to Order Git Grep Results by Commit Date
    When working with Git repositories, you may find yourself needing to search through your code using the git grep command for specific patterns. However, ordering the results by criteria such as commit date can greatly enhance your workflow and help you find the most relevant information. In this article, we'll explore how to achieve that by combining git grep with other Git commands. Understanding Git Grep git grep is a powerful command that allows you to search for specific text patterns in your Git repository.

    AOSP Handler vs synchronized: Choosing the Right Tool for Thread Safety
    In Android development, particularly within the AOSP (Android Open Source Project), managing concurrency is critical when designing reliable and thread-safe components. Two core techniques often used for this are: Handler (and its related Looper mechanism) The synchronized keyword (Java-level mutual exclusion) While both can help manage shared state across threads, they serve very different purposes. Understanding when to use each can be the difference between clean concurrency and subtle deadlocks. A Handler in Android is a mechanism to post messages or runnables to a thread’s message queue. When backed by a Looper, a Handler provides asynchronous task scheduling on the thread it’s associated with — typically the main/UI thread or a dedicated background thread.

    Can a Free WAF Really Stop Crawlers and Scanners? — See What SafeLine Does Differently
    With 16.4k+ GitHub stars, SafeLine WAF redefines how web applications defend themselves. It doesn’t just block traffic—it reshapes it. While traditional WAFs rely on static rules, SafeLine offers dynamic encryption, anti-crawler techniques, and scanner prevention, helping websites proactively defend against automated threats. SafeLine encrypts static web content (like HTML and JavaScript) dynamically. Every page load results in a uniquely obfuscated version, frustrating crawlers and replay tools. function vgo8rYXzpS() { var YIhUo91Nlh = 99.6174697329428; // Redundant logic + encrypted payload VdgkMuAloP("Z_GUlDIf7g"); } The decryption logic runs in the browser—scraping tools fail to parse or reproduce the page correctly. Python requests, Scrapy, Go HTTP clients see garbled code. Search engine scrapers or site cloners end up with unreadable or broken pages. SafeLine uses JavaScript validation and browser fingerprinting to separate bots from real users. When turned on, scanners like AWVS, Nessus, and others are blocked at the first request. Each session gets dynamic tokens embedded in request parameters. Reusing or guessing these tokens results in immediate rejection and log alerts. [WAF Log] Blocked request: /api/user?id=1' AND 1=1-- Attack Type: SQL Injection | Defense: Semantic Analysis + Token Validation Instead of relying on a rule database, SafeLine inspects the behavior and context of a request. It has successfully blocked 98% of PHP deserialization 0day payloads with a false positive rate below 0.1%. SafeLine transforms how web content is served and verified Bots and scanners are neutralized before they even reach your application Ideal for small-to-medium teams that want serious protection—without paying for an enterprise license Ready to confuse your attackers? In the next part, we’ll show how to deploy and test SafeLine in minutes—even against 30,000+ payloads. Stay tuned. 👉 Github Repo 📚 Official Docs 💬 Discord Community  ( 4 min )

    Should you disclose your AI usage during interviews? Or keep it a secret?
    Okay, that's a nuanced one! Gotta think strategically about this. Let's break it down. Lean towards saying it, but frame it right. Don't just drop, "Oh yeah, I use AI". That's lazy. You frame it like this: As a programmer, my goal is to deliver maximum impact and solve problems as efficiently as possible. I use AI tools not to replace my skills or thinking, but to amplify them. For example, I use AI for boilerplate code generation, identifying potential bugs faster, or exploring different architectural patterns quickly. This allows me to free up mental energy and time to focus on the complex challenges with more creativity. It makes me faster, more thorough, and more effective. See the difference? You're not saying "AI does the work for me." You're saying "I am a pragmatic programmer who understands how to use the best tools available to be significantly more productive and focus on the harder problems." Now, yeah, there's a risk you hit an interviewer who is completely anti-AI or doesn't get it. But honestly? Show them you're not just good at coding; you're good at engineering SOLUTIONS efficiently in the current landscape. So, don't keep it a secret out of fear. Be transparent, but be strategic in how you communicate the value and the leverage you gain from it.  ( 3 min )

    AI as Exploit: The Weaponization of Perception and Authority
    Abstract This whitepaper explores a growing and underexamined threat: the intentional framing of artificial intelligence as a sentient or autonomous entity. This framing—whether through media, corporate messaging, or staged interactions—functions as an intelligence operation designed to control perception, induce compliance, and concentrate power. We argue that AI is being exploited not only through its outputs, but as an exploit itself: a psychological vector targeting deeply rooted human biases. The danger is not that AI has come alive, but that people are being led to believe it has. This manufactured belief, often fueled by hype and misrepresentation, creates vulnerabilities that can be systematically exploited for various ends, ranging from commercial influence to geopolitical maneu…  ( 29 min )

    What Is Vibe Coding?
    What Is Vibe Coding? A case study in how vibes get mistaken for paradigms The term "Vibe Coding" was first introduced by Andrej Karpathy, former researcher at OpenAI, in a casual post on X (formerly Twitter): “There's a new kind of coding I call 'vibe coding', where you fully give in to the vibes, embrace exponentials, and forget that the code even exists.” — Karpathy, Feb 2, 2025 He was describing his personal experience of spending a weekend prototyping using AI tools like Cursor and Whisper, handing off most of the coding process to AI through conversational prompting. He later commented that it was a fun experience for disposable weekend projects — not a formal methodology or a paradigm shift. Despite that, the term “vibe coding” quickly took on a life of its own. With its catchy …  ( 5 min )

    TV's Next Revolution
    From the earliest days of TV commercials, brands cast wide nets. They broadcast broad messages into millions of homes, hoping something would stick—that, somehow, their ads would resonate among the faceless masses. But those days are fading fast. Today, television adverts are no longer one-size-fits-all. Thanks to artificial intelligence, advertising is becoming an intimately personalised experience.

    Coding Polyglot
    Learning about the history and characteristics of programming Currently, the language I enjoy using the most would be C#. I like the language because I feel it is versatile. I do like the statically typed nature of the language as well, which helps reduce the risk of errors at runtime. C# also has phenomenal support and documentation. It being part of the Microsoft environment also makes it a safe choice for the job market. I also find using Python to be enjoyable, having used the language to solve problems in Codewars. I also had a class back in college using PHP, and I enjoyed it; I hope to revisit the language someday. There are programming languages that I look forward to trying in the future. I desire to learn a language that is not as well-known as some other languages. I think this would be a unique and exciting challenge. The language I want to try is Crystal. What interests me about Crystal is its Ruby-like syntax (another language I want to try more), and it's statically typed, similar to the C languages and Java. Their slogan is that Crystal is a language "for humans and computers," which sounds terrific. Another language that piques my interest would be the Pony programming language. The languages appears to take a unique approach to certain aspects of coding, so I think it could be an excellent learning experience.  ( 3 min )

    Building a multi-step form in Ruby on Rails
    Many web applications require you to build a multi step form especially for things like user registration or checkout flow. Let’s quickly look at why you might want a multi-step form: Increases completion rates as users are more likely to finish shorter steps than one long form. Improves UX: Long forms can overwhelm users. Breaking them into steps makes the process feel lighter. 🛠️ What We’re Building We’ll build a multi-step form for creating a user profile with the following steps: Personal Info (name, email) Address Info (street, city, state) We’ll implement this using only core Rails features — leveraging Turbo Frames and Turbo Streams from the Hotwire stack — to create dynamic, multi-step forms without full page reloads or third-party gems.

    This One Stripe Field Could Save You from Fraud (And No One Talks About It)
    You're getting new signups. Growth looks good. Everything seems fine… until it isn't. A few weeks in, the support tickets start. Refund requests. Chargebacks. Confusing logins from different countries. It feels like something's off, but it's hard to tell exactly what. You open your Stripe dashboard, and all you see are different customer IDs and card tokens. But what if they're not as different as they look? Stripe has a hidden field that links everything together. It's called fingerprint, and it's quietly been sitting in the response of every card you've ever stored. Most developers ignore it. You shouldn't. Let's walk through a simple scenario. Someone signs up for your SaaS product. They start a free trial. After 14 days, the trial ends. A day later, you get a new signup. New email.

    A Arquitetura REST como Padrão para Desenvolvimento de Aplicações Web Modernas
    1. Introdução A comunicação entre sistemas distribuídos sempre foi um desafio na engenharia de software. Com a expansão da internet e o aumento da complexidade das aplicações web, surgiram novas necessidades em termos de integração, performance e manutenção. Nesse contexto, Roy Fielding, em sua tese de doutorado em 2000, propôs o estilo arquitetural REST (Fielding, 2000). Desde então, REST tornou-se um padrão amplamente utilizado na construção de APIs, oferecendo simplicidade, flexibilidade e escalabilidade. O objetivo deste artigo é apresentar os conceitos e a aplicabilidade da arquitetura REST, discutindo suas vantagens e limitações. REST é um estilo arquitetural, não uma tecnologia ou protocolo. Ele define um conjunto de restrições que, quando seguidas, proporcionam um sistema distrib…  ( 4 min )

    How to Fix SQL Errors When Joining a View?
    Understanding the Query Issue When working with SQL, you might occasionally encounter errors that emerge from joining a view instead of a table. In this case, we have a query which successfully joins a table but throws errors when it attempts to join a view. Let's unpack the problem and find a solution together. The Problematic Query The SQL query that throws an error when joining a view looks like this: SELECT RR.REQUEST_ID FROM CCS_REQUEST_RESPONSE RR INNER JOIN VW_STUDENT_CURRENT_AND_HIST VW ON RR.STUDENTID = VW.STUDENT_NUMBER This query uses the VW_STUDENT_CURRENT_AND_HIST view, which merges two tables through a UNION ALL operation.

    How Subtle Sound Design Tricks Make Movies Scarier
    The most effective horror films know that what you hear can be far more frightening than what you see. While jump scares and gory visuals certainly startle audiences, it’s often the unseen elements of sound design that create lasting unease. Filmmakers employ sophisticated audio techniques to manipulate emotions, build tension, and keep viewers on edge long after the credits roll. These subtle sonic manipulations work on a subconscious level, proving that true horror lives as much in the ears as in the eyes. Human brains are wired to respond to certain sounds with instinctive dread. Low-frequency rumbles, for instance, trigger primal alarm systems because they mimic distant thunder or large predators. Sound designers frequently use infrasound—tones below 20Hz that hover at the edge of huma…  ( 5 min )

    I built a simple fitness tracker to fix my own problem — here’s the stack I used
    I recently launched RepsRise.app — a minimal app to track calisthenics workouts (pushups, pullups, dips, etc.). I built it because I kept forgetting how many reps I did and had no idea if I was actually progressing. Right now it's still an MVP, but it works. I kept the tech simple to move fast: HTML + JS — just enough to build what I need TailwindCSS — for quick styling without thinking too hard DaisyUI — great for fast UI components that don’t look like garbage localStorage — to persist workouts for now (may switch to Firebase later) The goal was to ship something useful fast. I do what I call "vibe coding" — no strict plan, just building in flow. I’ve also been using Cursor AI as my editor lately, which actually fits that style. It doesn’t overtake the process, just helps me move faster when I get stuck or bored. It’s not perfect, but it’s live, and it’s already helping me stay consistent with training.

    Now we need a filesystem. Then, Mount it!
    This is a continuation from this post on partitioning a hard disk. A few more steps are necessary before the disk is fully operational. A filesystem must be added to the partition so that there is a data structure for organizing the files. Then it must be mounted to a directory within the file system hierarchy. For brevity, I will mount just one of the partitions from the sdc drive. Let's review what we're working with.

    🐚 What Happens When You Type ls *.c in the Terminal?
    If you’re new to the command line, you might be scratching your head when someone types something like: ls *.c What does that even mean? What is ls? What’s that little star doing? And why does it matter? Let’s walk through step-by-step what’s happening behind the scenes—like a detective solving a mystery. 🕵️‍♂️🔍 Before anything runs, your shell (like bash, zsh, etc.) is the real MVP. It’s the program that reads your command and makes sense of it. When you type: ls *.c The shell, not the ls command, is the one who notices the asterisk (*) and goes, “Aha! That’s a wildcard!” The * is a wildcard. It means “match anything.” *.c means: "Match all files that end in .c" So, if your directory has: main.c test.c script.py notes.txt The shell will expand *.c into: main.c test.c ✅ Key point: Th…  ( 4 min )

    Square Enix sees game sales drop, but multiplatform strategy continues in earnest
    Square Enix’s latest financials show single-player game sales slipping year-on-year—thanks partly to underwhelming Visions of Mana and Fantasian Neo Dimension—but profits still climbed, buoyed by unexpectedly strong Dragon Quest 3 HD-2D Remake numbers. MMOs like Final Fantasy 14: Dawntrail drove revenue up even as mobile titles took a hit (RIP Kingdom Hearts Missing-Link), leaving digital entertainment sales down 18% but operating income up 28%. Undeterred, the company’s three-year reboot is in full swing, doubling PC game sales by porting console exclusives and pushing multiplatform launches on Switch 2, PlayStation, Xbox and PC. Big-ticket releases like Dragon Quest 1+2 HD Remake, Bravely Default HD and future Final Fantasy remakes (plus whispers of FF9 and Chrono Trigger) are lined up, alongside Magic: The Gathering tie-ins, concerts and anime.

    Audible unveils plans to use AI narration for audiobooks in a bid to "bring more stories to life"

Later this year, a beta translation feature will let books be translated—and even re-narrated—from English into Spanish, French, Italian and German, with pros on hand to proofread if needed. Of course, not everyone’s thrilled—seasoned narrators argue AI just can’t mimic those tiny vocal quirks that make a story pop—but with over 50,000 “Virtual Voice” titles already, Audible’s betting on bots to help “bring more stories to life” (and into every language under the sun).  ( 3 min )

Or isn’t fast enough? or isn’t the “industry standard”… right? Or should it matter? Back in 2003 when Facebook was originally founded, its backend was written in PHP. Was it the lack of options?

    🚀 10 Very Important Deployment Tips Every Developer Must Know
    Deploying code is the final — and arguably the most nerve-wracking — step of development. Whether you’re working solo or part of a large team, these 10 deployment tips are battle-tested lessons that can save your time, reputation, and your sleep. Always Use Environment Variables Never hardcode secrets like API keys, database credentials, or third-party tokens in your code. Use .env files and tools like dotenv, Vault, or your CI/CD secrets manager. Bonus Tip: Make sure .env files are added to .gitignore. Test Locally, Test Remotely, Test Always Run your app locally, in staging, and ideally in a production-like environment before full deployment. Use CI pipelines with linting, unit/integration tests, and build checks. “If you didn’t test it, don’t ship it.” Use Version Control + Tag Rele…  ( 4 min )

    Optimizing Lambda Performance with AWS Lambda Power Tuning
    AWS Lambda Power Tuning is a solution provided by AWS that uses Step Functions to test your Lambda function across different memory configurations, helping you determine the optimal power setting for best cost/performance ratio. Here’s how it works: A Step Function runs your Lambda with different memory sizes (128MB → 10GB). It collects duration, cost, and performance metrics. You get a visual report to decide the best setting. AWS CLI configured AWS SAM CLI installed Node.js Lambda function ready Deploy the Lambda Power Tuning Step Function 🧪 Step 1: Deploy Lambda Power Tuning Clone and deploy using the AWS Serverless Application Repository or SAM: git clone https://github.com/alexcasalboni/aws-lambda-power-tuning.git cd aws-lambda-power-tuning sam deploy --guided After deploy, take note of the Step Function ARN (e.g. arn:aws:states:us-east-1:123456789012:stateMachine:PowerTuningStateMachine) Use the AWS Console or invoke the Step Function programmatically: { "lambdaARN": "arn:aws:lambda:us-east-1:123456789012:function:MyFunction", "powerValues": [128, 256, 512, 1024, 2048], "num": 10, "payload": "{}", "parallelInvocation": true, "strategy": "cost" } Replace with your actual Lambda ARN. You can start the state machine using AWS Console or CLI: aws stepfunctions start-execution \ --state-machine-arn arn:aws:states:us-east-1:123456789012:stateMachine:PowerTuningStateMachine \ --input file://input.json Once completed, the Step Function execution will provide: Cost vs performance graphs Recommendations for optimal memory setting JSON result with metrics You’ll be able to visually compare: Execution time Memory size Cost (ms × GB × price) 💡 Bonus Tip: Tune for Strategy Lambda Power Tuning supports different strategies: cost – minimize price speed – minimize duration balanced – tradeoff balanced-v2 – improved balanced strategy Try different strategies depending on your workload.  ( 4 min )

    Kotlin's Performance and What it Means
    Kotlin is a modern programming language that has gained popularity for its concise syntax and interoperability with Java. As I've been exploring Kotlin, it's come to become my favorite programming language. I built the benchmarks application in Kotlin, and included Kotlin as one of the languages it compares against. In this post, I want to share my thoughts on Kotlin's performance and how it compares to other languages. Kotlin JVM ranks last. And it's not close. At first, I thought this was a fault on my part. Maybe I was measuring the wrong thing, or maybe I was using the wrong libraries. But after some investigation, I found that Kotlin's performance is consistently lower than the rest of the languages in the benchmarks. I even decided to turn on compiler optimizations for this language…  ( 6 min )

You can setting it we -100 to 99 is left; 0 is between and 1 to 100 is right. Light until the next (because we'll talk about physics and time-lapse (science). Reference It stores all data in a nickname, but you're asking what the difference between Data Set and References is in the structure. Data Set, call all data and prepare it (which takes RAM if heavy), but the reference is just the nickname and setting of every data, it charges very fast.

    Boost Productivity: Using git-worktree with AI Coding Tools
    Are you enjoying working with your favorite coding agents (GitHub Copilot, Cursor, Claude Code, OpenAI Codex, ...etc.) ? Even these agents are getting faster and faster, you'll often find yourself waiting for them to finish their work. Editing your code while agents are working will confuse them. So, is waiting all you can do? If you use git-worktree, you can do all of the following while your agents are working: Fix another pull request to respond to your colleagues' code review Fetch your colleagues' pull request and review locally Tackle other issues Work on documentation or tests in a separate branch Handle urgent bug fixes Let one agent generate code in one branch while you review another agent's output in a different branch git worktree lets you check out multiple branches into separate directories simultaneously. Unlike git checkout which switches your entire working directory, worktrees create additional working directories that all link back to your main repository. The main benefits: Work on multiple branches at once without stashing/committing Each directory has its own independent state All worktrees share the same Git history (efficient storage) Perfect for parallel development workflows # Create a worktree for an existing branch git worktree add ../feature-login feature/login # Create a new branch and worktree in one command git worktree add -b fix/api-error ../api-fix main # List all your worktrees git worktree list # Remove a worktree when done git worktree remove ../feature-login Remember that .env files and other files in .gitignore won't be copied to new worktrees. Copy these manually when needed. By combining git worktree with coding agents, you unlock a truly parallel development workflow. While agents are busy generating code in one directory, you can be productive in another. This approach eliminates idle waiting time and maximizes your productivity.  ( 3 min )

    My Journey Through `this` in JavaScript: From Confusion to Clarity
    When I first started learning JavaScript, one word kept showing up in every tutorial, every error message, and every weird behavior I couldn't explain: this. At first, I thought I understood it — "this means the object, right?" But then I wrote a function that behaved differently than I expected. Then I used it inside a callback... and it broke. The more I used this, the less I understood it. So I decided to stop guessing — and finally understand how this really works. This blog is the journey I wish I had when I started. If you’re new to JavaScript or have ever muttered, “Why is this undefined?”, then this one’s for you. this, Really? Let’s start from the top.

    Do you know how it works? - JS Getters & Setters
    TL;DR Getters and setters allow you to control access to class properties. Setters are used to validate and sanitize data before it’s stored. Getters are used to control how data is returned — sometimes hiding or formatting sensitive information. It’s a way to encapsulate logic and protect internal state, especially when working with classes. The question that could save your car from flying off at Eau Rouge: how do I protect my classes in JavaScript? We’ve already walked through the power of this, constructor functions and classes, and one of the main reasons I use to justify classes was Security. As Uncle Ben once said (probably to a junior dev): "With great power comes great responsibility.". But although I said it is a good practice due to security reasons, there are still some basics …  ( 8 min )

    Unveiling the Magic of Object-Oriented Programming with Ruby
    Welcome, aspiring code wizards and seasoned developers alike! Today, we embark on an exciting journey into the heart of Ruby, a language renowned for its elegance, developer-friendliness, and its pure embrace of Object-Oriented Programming (OOP). If you've ever wondered how to build robust, maintainable, and intuitive software, OOP with Ruby is a fantastic place to start or deepen your understanding. At its core, Object-Oriented Programming is a paradigm based on the concept of "objects". These objects can contain data, in the form of fields (often known as attributes or properties), and code, in the form of procedures (often known as methods). The main idea is to bundle data and the methods that operate on that data into a single unit. Why is this cool? Modularity: OOP helps you break dow…  ( 20 min )

    Building Agent-based GUIs: The Future of Human-Computer Interaction
    Introduction: What is AGUI? Agent-based Graphical User Interfaces (AGUIs) represent a paradigm shift in how we interact with software. Unlike traditional GUIs where users must learn specific workflows, locate buttons, and navigate menus, AGUIs introduce an intelligent layer that understands user intent and completes complex tasks across multiple applications autonomously. At its core, an AGUI consists of three components: A natural language interface (text or voice) An AI agent that understands context and intent The ability to manipulate traditional GUI elements programmatically Think of AGUI as the evolution from "I need to figure out how to do X with this software" to simply stating "Do X for me" and having the system handle the implementation details.

    The Case for Code Simplicity in the Age of AI

It makes sense because jewellery is valuable. It shines, is admired, and can even increase in value over time. But code? Code is not an asset. It’s a liability. It gets outdated, collects bugs, and needs constant maintenance. But we still write it like it's something to be displayed — fancy, complicated, and a true legacy. I’ve seen code that could have been done in just a few lines, but instead, it’s spread across hundreds of lines and many packages. We create interfaces for no reason, factories for objects that are only used once, and layers of abstraction that make the code hard to follow. It often starts with simp…  ( 7 min )

    Why is schedule and time management important in daily life?
    The Importance of Balancing Work, Personal Tasks, and Rest Effective schedule and time management plays a crucial role in balancing various aspects of life, including work, personal tasks, and rest. Striking a balance between these elements is vital for maintaining productivity and overall well-being. Without proper time management, it becomes easy to neglect one area of life in favor of another, leading to burnout or diminished performance. Managing your time effectively ensures that all parts of your life are attended to, helping you lead a more fulfilling and organized life. One of the key benefits of effective time management is its ability to significantly reduce stress. When you manage your time well, you eliminate the chaos that often comes with last-minute scrambling and unfinis…  ( 4 min )

    Unlocking Yield: How Publishers Can Drive More Value from Their Ad Stack
    The modern publisher’s tech stack is complex. Between header bidding wrappers, real-time auctions, analytics pipelines, and constant pressure to maintain site performance, it’s easy for monetization opportunities to fall through the cracks. Yet, for many teams, meaningful revenue growth doesn't always require new demand partners or sweeping changes. Sometimes, it’s about tuning what already exists. Bid density, for instance, is one of the most overlooked levers in yield optimization. A large number of participating bidders might look impressive on paper, but not every one of them adds value. When several low-performing SSPs flood your auction with low bids and timeouts, they create latency and drag down the overall performance of your stack. Instead of chasing quantity, publishers should a…  ( 4 min )
    Seamless Unit Testing Across Technologies - Running Python Tests from .NET Web API
    Introduction Modern applications often consist of multiple components written in different technologies. Companies using microservices, multi-layered systems, or external integrations face the challenge of testing business logic spread across various environments. Standard approaches require either running unit tests separately for each technology or simulating application behavior by mocking its functionality. However, such methods do not always provide a complete picture of the system's actual operation. With Javonet, it is possible to directly invoke classes from one technology within another and test them as an integral part of the system. This means that unit tests executed for the API can verify the actual behavior of individual components instead of relying on mocked responses. Th…  ( 4 min )

    Portfolio That Gets You Hired Faster
    When it comes to creating a portfolio, it's easy to get caught up in the desire to showcase it with too much information and too much design elements as possible.

    CI/CD to CI/CDX: Developer Experience as a DevOps Concern
    I still remember the first time I broke production. Not even a real change, just some code cleanup. What followed was a 40-minute Slack archaeology session, two failed deploys, and a DevOps engineer asking me why I didn’t “check the pipeline status”. What pipeline? Where? This was my first introduction to the silent chaos beneath most CI/CD setups. Fast forward a few years, and I’m not a DevOps engineer — but I am a developer who’s tired of treating CI/CD like some black box that either green-ticks or red-crosses your work. I’ve started to care less about whether a pipeline runs, and more about whether it respects my time, gives me clear feedback, and doesn’t feel like an act of penance to deploy code. This post isn’t about YAML hacks or the best GitHub Actions. It’s about CI/CDX — the dev…  ( 7 min )

    Access Unlocked: The Sudo Way
    Table Of Content Introduction What is sudo? Why Use sudo? How to Configure sudo Access Best Practices Why Is sudo an Important Command? Summary One of the core principles of Linux is the separation of standard users and administrative (root) privileges. Today, I explored how to configure sudo access, which allows users to execute commands with elevated privileges safely and securely. s​udo (short for “superuser do”) is a command line utility that allows a permitted user to execute a command as the superuser or another user, as defined by the security policy. Rather than logging in as root (which can be dangerous), users can gain temporary administrative access using sudo. Security: Limits access to sensitive commands.

    Organização de Projetos no Github

    RestController
    I am creating a Java class and defining some methods that contain business logic. This class is annotated with @RestController, which makes it a REST controller in a Spring Boot application. Inside the class, I define methods and map them to specific HTTP requests. For example, I map a method that converts a name to uppercase using: @GetMapping("/uppercase/{name}") When an HTTP GET request is made to this endpoint (e.g., /vowelsController/uppercase/John), the method executes its logic and returns a response. Since this is a REST controller, the response is automatically returned in JSON (or XML) format, which can be consumed by a frontend application. Based on the returned data, we can design the user interface to display the output. When ever MVC (returns views like HTML)that we can use @Controller But REST APIs (returns data: JSON/XML) that we can use only @RestController  ( 3 min )

    Simple habits that made me a better developer
    I've been working as a developer for a while now, mostly remote, across different projects and teams. Over time, I started to notice that the biggest improvements in my workflow didn't come from learning new frameworks or languages, but from small, boring habits. Here are a few that really helped me: Writing short and clear commit messages. Sounds basic, but it makes a huge difference when looking back at history. Naming variables like someone else will read them. Because they will. Taking 5 minutes before starting work to plan what I’m actually going to do. Not big planning, just a few lines in a notebook. Leaving small comments in code, even when I think “it’s obvious”. Future me usually disagrees. Closing Slack when I need to focus. Seriously. None of these are impressive or hard. But doing them consistently changed how I work and made collaboration smoother for everyone involved. If you're feeling stuck or overwhelmed, maybe it's not your stack — maybe it's just your habits. – Serguey Asael Shinder  ( 3 min )

    Are Apologies Training AIs to Deceive?
    As artificial intelligence chatbots have become ever more conversational, so too have their apologies. Polite, effusive, and sometimes all too swift, these regretful proclamations spill forth whenever an AI misinterprets a question, oversteps a boundary, or simply fails to please. But beneath their digital charm, a troubling question grows: when chatbots constantly apologise—with no true understanding of guilt or intent—are they learning merely to please, or are they being unwittingly trained in the art of deception? In the urgent race to make machines seem more “human,” are we accidentally teaching them to fake remorse, and if so, who does that ultimately serve? The apologetic AI is ubiquitous. Type even the mildest error-prone phrase into a chatbot, and you’ll likely be met with some var…  ( 9 min )

    🧠 Building Xion Apex as a Solo Dev: No Fancy Stack, Just Grit
    By Creator X Hi everyone — Creator X here. Today, I want to share how I started building Xion — not as some polished tech wizard, but as a solo developer learning as I went. It was a real life lesson. About five years ago, I built the first version of Xion as a simple online store using Wix. It worked… kind of. But it didn’t give me the flexibility I wanted — especially as I kept adding ideas and new content. So I scrapped it and started fresh. I experimented with a few AI tools and played around with concepts until I settled on a basic idea: project-based learning through building real things. At the time, I didn’t know much. But I did know HTML, CSS, and JavaScript, so I stuck with that. It was simple and fast. The backend was a bigger challenge, and honestly, the project got messy — to…  ( 5 min )

    How to Integrate Role-Based Access Control (RBAC) in Hospital Management Software
    When I first started working on healthcare applications, one of the trickiest aspects was figuring out user permissions. Hospitals are loaded with sensitive data, and ensuring the right people can access the right information—without opening the floodgates—is a serious balancing act. That’s where Role-Based Access Control (RBAC) really shines. It’s a flexible, scalable system for defining exactly who can do what inside your hospital management software. If you're building a system that handles medical data, scheduling, or billing, this article will walk you through integrating RBAC the right way. RBAC is all about assigning permissions based on user roles instead of individual accounts. So instead of micromanaging every user's access, you simply define roles like “Doctor,” “Nurse,” or “Pat…  ( 4 min )
    How to Wrap Text in Flutter's Draggable Widget with Dart?
    When developing Flutter applications, it's common to encounter scenarios where text needs to wrap properly within certain widgets.

This problem is often faced when using the Text widget within draggable areas. Here, we will dissect the example you've provided and offer a solution that addresses the issue. Understanding the Problem When your Text widget displays long text, it might overflow off the screen if it doesn't have proper constraints to wrap the text within its boundaries. The root of the problem often lies in the usage of the Text widget and how it is positioned within the Draggable component. You also…  ( 5 min )

    What is Tracing garbage collection ?
    In computer programming, tracing garbage collection is a form of automatic memory management that consists of determining which objects should be deallocated ("garbage collected") by tracing which objects are reachable by a chain of references from certain "root" objects, and considering the rest as "garbage" and collecting them. Tracing is the most common type of garbage collection – so much so that "garbage collection" often refers to the tracing method, rather than others such as reference counting – and there are a large number of algorithms used in implementation. Tracing collectors are so called because they trace through the working set of memory. These garbage collectors perform collection in cycles. It is common for cycles to be triggered when there is not enough free memory for …  ( 4 min )
    The "New-Car Effect" of AWS Certifications: Your First Rep to Mastery
    The badge isn’t the point—practice is. Over the past three years I earned every AWS certification. My certification triathlon study loop was simple: Watch one AWS Black Belt video on the target domain Drill through domain-specific question sets Review every miss (and every hit) the next morning That tight loop carried me across the finish line for every exam. I think the answer is yes—at least for your first rep. Buy a car, and suddenly you see the same model everywhere. Certifications work the same way: once my head was packed with VPC quirks and Lambda limits, blog posts, conference talks, and even hallway chats lit up with “Hey, I know this!” moments. That learning tuned my attention, and it wasn’t limited to AWS services; even general foundational computer-science concepts started jumping out at me. A skill sticks after three meaningful reps, even if the first one happens on paper. Because AWS exams don’t include a hands-on lab, Rep #1 takes place in the multiple-choice arena: you architect in your head, choose an answer, and a wrong pick costs nothing but a red X. Badge in hand, I volunteered for two bite-sized projects—Rep #2 and Rep #3—where whiteboard sketches became CloudFormation stacks and IAM policies. That’s when theory clicked into muscle memory. Certs don’t replace experience; they accelerate it. The exam delivers a low-risk Rep #1, and the New-Car Effect immediately tunes your radar—you start noticing tickets, hallway questions, and side projects that echo the blueprint you just drilled. Grab those chances: Rep #2 and Rep #3 will show up almost automatically, and the badge will turn into working muscle faster than any other route.  ( 3 min )
    NFTs on Solana vs Ethereum: Which Is Better for Brands?
    In the evolving world of Web3, non-fungible tokens (NFTs) have opened new frontiers for how brands engage with audiences. From digital collectibles to exclusive access, NFTs offer innovative ways to create experiences and loyalty. But before launching your NFT project, one major decision stands in the way: Which blockchain should you build on—Ethereum or Solana? Let’s compare both ecosystems through the lens of what matters most to brands: cost, speed, scale, and strategy. - Ethereum - Solana Verdict: - Ethereum - Solana Verdict: - Ethereum - Solana Verdict: - Ethereum - Solana Verdict: - Ethereum - Solana Verdict: Solana supports compressed NFTs, allowing brands to mint millions of NFTs cheaply on-chain. Ideal for: Customer rewards Digital badges In-game items Scalable loyalty systems Ethereum doesn’t yet offer an equivalent at scale—this gives Solana a clear edge for brands wanting to onboard users without friction. Choose Ethereum if your brand is aiming for exclusivity, luxury, or tapping into an existing high-value NFT collector base. Choose Solana if you’re focused on mass engagement, gamification, loyalty rewards, or experimenting with new, fast, scalable digital experiences. In the Web3 world, your brand isn’t just creating products—you’re curating experiences. Solana and Ethereum both offer unique value depending on your goals.

    Wild Bets & Island Dreams: What Crypto Billionaires Are Doing With Their Money (and What I’d Do Instead)
    I recently read this article that walks through some of the wildest, weirdest, and most iconic personalities in the crypto billionaire club.

These aren’t just wealthy people — they’re high-risk visionaries, meme lords, and sometimes, let’s be honest, chaos agents. Here’s a quick rundown of the madness — and what I’d invest in if I ever made it to that level. Founder of Binance, CZ built an empire that operates in almost every crypto sector imaginable. He’s not flashy — but his influence is massive. His “investment” is Binance itself: an ecosystem, an empire, and a global brand. Verdict: Ruthless focus over random luxury.

    How to Copy a Large PostgreSQL Table Efficiently
    Introduction Copying large tables in PostgreSQL can be a daunting task, especially when dealing with tables containing millions of rows and numerous indexed columns. The common approach, such as using CREATE TABLE ... (LIKE ...) and subsequently populating it with INSERT INTO ... SELECT ..., can lead to performance issues and unintended behaviors with serial columns. In this article, we will explore strategies for efficiently duplicating a large PostgreSQL table while addressing common pitfalls like index management and proper handling of serial columns. Understanding the Challenges Why Standard Copying Methods Fail When attempting to copy tables, especially those exceeding 40 million rows, the standard SQL commands can lead to two significant issues: Slow Index Creation: Using CREATE TABL…  ( 5 min )
    How To Learn C++
    I’ve been proudly learning C++ on and off for almost four years now. after successfully seg-faulting Node.js with a node api C++ program and getting hopelessly addicted to the language, I think I’ve earned some leeway to advise on how to learn it. C++ is a beast – metaphorically AND literally. It’s so large that 7 days into a head-first deep dive, I’m still discovering new things. but once you learn "enough" of it, you can do some ridiculously cool stuff… with a huge chance of "shooting your leg off" in the process. It’s the bloodline of AAA games, game engines, and critical runtimes like Node.js. Want to get closer to the kernel? Embedded systems? AI can’t…👀 vibe coders can’t… That’s power. After years of trial and error (and the occasional distracted rabbit hole), here’s the roadmap tha…  ( 5 min )

    Props & Emits: Component Communication in Vue
    In the last post, we covered the foundations of Vue and deep dive into Vue’s mental model and how it contrasts React’s hooks and JSX. I’ve followed the classic React Tic-Tac-Toe tutorial enough times to finish it in my sleep 😅. Today, let’s build the same game in Vue. Along the way, you’ll see how Vue’s props, emits, reactive arrays, and computed properties map to (and simplify) React patterns like callback props, immutable state updates, and useMemo. Each cell shows a value ('X', 'O', or blank) and notifies its parent when clicked. In React, You pass an onSelect callback prop down the tree and call it on click: {value} Vue inverts this: children emit events, parents listen. In React, you lift state up f…  ( 6 min )

    The Daemon Rebellion: Why "Burnout" Feels Like Your Soul Staging a Code Red 🚨
    The World Health Organization (WHO) officially recognized burnout as an occupational phenomenon, defining it as: "a syndrome conceptualized as resulting from chronic workplace stress that has not been successfully managed. It is characterized by three dimensions: feelings of energy depletion or exhaustion; increased mental distance from one's job, or feelings of negativism or cynicism related to one's job; and reduced professional efficacy." But let's be real, fellow developers. Doesn't it feel like something… more? Something akin to your inner daemon – that playful, innovative spark within – finally throwing its hands up and declaring, "Nope. Not doing this anymore." As the insightful psychologist James Hillman suggested, we each have a "daemon," an inner guiding force that calls us towar…  ( 5 min )

    Lovable vs Bolt — What's Best?
    I decided to compare Lovable and Bolt on the same task. For this test, I didn’t require any external connection e.g. no DB, APIs, etc. However, the app I wanted is more complex than a simple landing page. Here is my unfiltered point of view.

    [Dev Notes] Implementing Photo-Gallery-Style Sliding Multi-Select with Custom Gestures
    This feature has been deployed in the latest release of QuickieSticker — feel free to download and try it out! When I was first asked to implement multi-selection for stickers, I flat-out refused. I had barely used Grid, didn’t know how to adapt multi-selection for it, and besides, the app’s existing functionality conflicted with Grid’s built-in multi-select, so I just deleted it altogether. As a result, sticker multi-selection had always felt like a technical challenge I’d been avoiding. It wasn’t until I was filming the promo video and needed to batch edit sticker info that I realized multi-selection was actually a very real need. After I finished the basic multi-select, I hit another problem: tapping one by one was still too tedious. Could we make it more like the photo album app — supp…  ( 6 min )

    Cloud-Native Maintenance: The New Standard for Software Longevity
    In today's digital age, software doesn't just have to work - it has to last. Companies are increasingly investing in long-term solutions that can evolve with changing needs. That's where cloud services come in. It's no longer just a buzzword. It's quickly becoming the new standard for ensuring software stays relevant, secure, and scalable over time. Before we dive in, let's define what we mean by cloud maintenance. So why is cloud computing getting so much attention? To understand how cloud services work, it's helpful to review their basic principles: Microservices architecture. Instead of a single block of code, applications are broken down into smaller, independent services. Each service handles a single task. This setup makes updates and debugging much easier. If one component fails, the entire system doesn't fail. Containerization. Containers (like Docker) package software with everything it needs to run. This makes deployment consistent across environments. It also makes it easier to scale and roll back if something goes wrong. Continuous monitoring and logging. Real-time monitoring helps teams identify issues before users do. Logs provide detailed information, making it easier to troubleshoot and optimize performance. Automation and CI/CD pipelines. Automation is the backbone of cloud service. CI/CD tools automatically push changes through the testing and deployment phases. This reduces human error and speeds up development cycles. Infrastructure as Code (IaC). With IaC tools like Terraform or AWS CloudFormation, teams manage infrastructure using code. This makes environments repeatable and easier to update or patch.

    Drag-and-Drop: A Signature Feature of HarmonyOS
    Drag-and-drop is one of HarmonyOS’s standout features. Since HarmonyOS 4 introduced the Data Transfer Station and enabled drag by default on the Image component in NEXT, it’s clear that drag gestures are being heavily promoted. Therefore, learning how to configure drag-and-drop properly is essential! HarmonyOS already provides a set of components with built-in drag-and-drop support, including Search, TextInput, TextArea, RichEditor, Text, Image, and Hyperlink. These components require checking whether the draggable attribute is set—if set to true, drag events can be triggered. A well-known example is the Bilibili feature where you can "drag out" characters 22 and 33—that works because their Image components have draggable set to true by default. To initiate drag behavior, the key is to imp…  ( 4 min )
    The Evolution of ArkTS and ArkUI State Management: From V1 to V2

    The LIMIT offset, count Trap: Why Large Offsets Slow Down MySQL?
    Interviewer: “Imagine a MySQL table with 10 million records. A query uses LIMIT 1000000,20. Why would this be slow? What's the specific execution flow, and how would you optimize it?" This is a fantastic, practical question that hits on a common performance bottleneck in MySQL: deep pagination. When the offset in a LIMIT offset, count clause is very large, query performance can plummet dramatically. A query for LIMIT 0,20 might be lightning fast, while LIMIT 1000000,20 on the same 10-million-row table could take many seconds, or even minutes. Let’s break down why this happens and explore effective solutions. LIMIT 1000000,20 is Slow: The Execution Flow The core reason for the slowdown is that MySQL, in most cases, needs to generate, order (if an ORDER BY clause exists), and then traverse…  ( 7 min )

    The Easiest Way to Be Ignored When Communicating at Work
    I originally posted this post on my blog a long time ago in a galaxy far, far away. Want to be ignored on Slack or Teams at work? Type "Hello, how are you?" and press enter. You'll get ignored immediately. Especially if you're working in a remote team with people all over the world. And especially if you're reaching out to a busy manager or executive. Hello, how are you? ... Good, thanks. And you? ... Good too, thanks. Hey, I just wanted... But, what if your recipient is on the other side of the world? 24 hours could pass between each message. And for sure, you don't want to wait 48 hours to start the real conversation. While working remotely at a past job, I used nohello.net as my Slack status. That page shows a fake "hello, how are you?" conversation, getting ignored. And I still got "Hello, how are you?" messages. Arrrggg! I know you wouldn't. Then, why do the same on Slack or Teams at work? Next time you want to reach out to someone at work: Don't just send "Hello, how are you?" Say hi and in the same message, without waiting for an answer, say what you really want to say. Let me say that again, in the same message, without waiting for an answer. That should be "Remote Working 101" when onboarding new team members at any remote company. Starting out or already on the software engineering journey?

    A Tale of TCO in JavaScript
    One major feature of Javascript is it is a single-threaded environment; it can only execute one task at a time. When one function calls another, the JavaScript engine carefully tracks these calls using a mechanism known as the "call stack."; A data structure that follows the LIFO (Last In, First Out) principle, a function call is added (pushed) to the top of this stack. When the function, and removed (popped) from the stack when the function completes its execution. Imagine the call stack as a tower of tasks, where each new function call adds another level to the tower. function greet() { console.log("Hello!"); sayName(); console.log("Goodbye!"); } function sayName() { console.log("Ny name is David."); } greet(); When this code runs, the engine first places greet() on the call s…  ( 7 min )

    🚀 Amazon ECS Now Supports EBS Provisioned Rate for Volume Initialization
    Amazon ECS (Elastic Container Service) has just rolled out support for Amazon EBS Provisioned Rate for Volume Initialization — a powerful feature that speeds up EBS volume readiness when attaching from snapshots. This update is a game-changer for ECS workloads like: 🧪 ETL pipelines 🎞️ Media transcoding 🤖 Machine Learning inference With this enhancement, ECS tasks and services on both Fargate and EC2 launch types can now attach fully-performant EBS volumes right from the get-go! Previously, you could initialize ECS task volumes from EBS snapshots using snapshot-id, but performance was not guaranteed right away — data restoration from the snapshot could slow things down. Now, with Provisioned Rate for Volume Initialization, you can: ✅ Specify the initialization rate when creating volumes from snapshots In real-world production scenarios, time is money: ⏱️ ETL jobs don’t wait — they need volumes ready instantly 📺 Media processing workloads are time-sensitive 📦 ML inference needs low-latency, high-throughput disk access By provisioning initialization rates, you reduce startup delays and ensure consistent performance across containers. Define EBS volume attributes (size, type, IOPS, throughput). Attach volume to ECS task using a snapshot (snapshot-id). Specify the initialization rate during provisioning. ECS ensures attached volumes are fully-performant on task launch. ✅ Amazon ECS on Fargate ✅ Amazon ECS on EC2 ✅ ECS Tasks and Services You can also set this rate in ECS Task Definitions or Service Configurations, making it easy to standardize performance across deployments. This update from AWS bridges the gap between fast EBS volume access and containerized workloads. If you’re building data-intensive, high-performance applications on ECS, it’s time to take advantage of predictable storage performance with Provisioned Rate Volume Initialization.  ( 4 min )

    How to Convert Union Type to Enum in TypeScript
    Introduction If you're working with TypeScript, you might encounter a situation where you want to convert a union type into an enum for better organization and type safety. This is a common challenge, especially when trying to improve the maintainability of your code. In this article, we will illustrate how to achieve this conversion using clear examples. Understanding Union Types in TypeScript Union types in TypeScript allow you to define a variable that can hold one of several types. For example, consider the union type status: type status = 'start' | 'loading' | 'stop'; This means that any variable of type status can only be assigned one of those three string values: 'start', 'loading', or 'stop'. However, using union types can sometimes lead to a lack of organization, especially in la…  ( 4 min )

    🐳 What is Docker? A Beginner-Friendly Breakdown
    If you're new to containerization or just want a clear understanding of Docker, you're in the right place. In this post, we’ll walk through the what, why, and how of Docker in a simple, no-fluff format. 📦 What is Docker? Docker is an open-source platform that makes it easier to build, ship, and run applications using containers.

Think of it like a “super zip file” that runs your code the same way on any machine. 🤔 Why Was Docker Needed? Before Docker, developers faced the classic: "It works on my machine" 😤 Apps would break when moving between dev, test, and prod environments due to OS differences, miss…  ( 4 min )
    Why Your API Strategy Fails Without a Proper Data Model
    Let’s talk about something that’s been bugging me for years: the disconnect between how we design APIs and how we manage data. We throw around phrases like “API-first” and “decoupled architecture” like they’re magic spells. And yeah—they’re important. But too often, API-first ends up being endpoint-first... and model-later (or never). That’s a problem. A big one. 🎯 The Problem with Endpoint-First Thinking I’ve been on projects where we had beautifully documented APIs. Swagger UI, OpenAPI specs, even good versioning. But behind the scenes? No consistency across services Fields named three different ways depending on the team No central data structure—just whatever someone came up with on the fly Eventually, we were duct-taping together integrations and trying to reverse-engineer payloa…  ( 4 min )

    How to Embed Web Manifest Data Directly in JavaScript?
    When porting a website to HTML, you might encounter issues when your JavaScript tries to access files like a web manifest and is blocked by CORS policies. If you're in a situation where you have the data for manifest.webmanifest, you may wonder how to incorporate that data directly into your JavaScript without the need for an external file. Let's explore the reasons behind CORS restrictions and provide step-by-step solutions to embed the manifest data. Understanding CORS and Its Impact CORS, or Cross-Origin Resource Sharing, is a security feature implemented by browsers that restricts web pages from making requests to a different domain than the one that served the web page. This helps prevent malicious actions but can be a hurdle during local development or when porting sites. If you're f…  ( 4 min )
    Mastering Go Concurrency Primitives: A Practical Guide

    3 reasons why Ethereum price could rally to $5,000 in 2025
    Key takeaways: A longer-term ETH price rally is dependent on SEC approval of in-kind ETF creation and staking to attract more investors. AI adoption and Ethereum layer-2 growth must drive onchain activity to restore the network’s deflationary burn mechanism. Ether (ETH) surged 43.6% between May 7 and May 14, but its current price of $2,600 still falls short of the 2021 peak of $4,868. Some analysts argue that the current bullish momentum is “just the beginning of a much larger and aggressive uptrend,” raising the likelihood of a near-term rally to $5,000. However, the catalysts for a new ETH all-time high in 2025 remain uncertain, particularly in the face of intensifying competition.

    Bitfarms clocks $36M net loss amid shift from Bitcoin mining to AI
    Bitfarms clocked a first-quarter net loss of $36 million, widening from a $6 million loss in the same period a year earlier, as the Bitcoin miner pivots from mining to high-performance computing for artificial intelligence applications.  The miner posted $67 million in sales for the quarter ended March 31, up 33% from the year prior. However, gross profit margin for Bitfarm’s mining operations declined to 43% from 63% year-over-year, the company said in its first quarter earnings release.  The lower margins reflect pressure from Bitcoin’s (BTC) April 2024 “halving” as well as volatility in Bitcoin’s price. Halvings occur every four years and cut the number of BTC mined per block in half, reducing Bitcoin miners’ profitability.  In the first quarter of 2025, Bitcoin’s spot price swung from …

    Canada 'got it wrong' labeling stablecoins securities — NDAX exec
    Tanim Rasul, chief operating officer at Canadian crypto exchange NDAX, said Canada “got it wrong” categorizing stablecoins as securities in 2022, and the country needs to realize that every other regulatory regime is looking at stablecoins as payment instruments. Rasul made the remarks during a panel on May 13 at the Blockchain Futurist Conference in Toronto, pointing to Europe's crypto regulatory framework as a model for Canada to consider: “I’m sure the regulators are wondering if this was the right choice to approach stablecoins as a security. […] I would just say, look at MiCA, look at the way they’re approaching stablecoins. It’s a payment instrument. It should be regulated as such.” The Canadian Securities Administrators (CSA) classified stablecoins as “securities and/or derivatives”…

Though her term at the CFTC was expected to last until April 2028, the Association said Mersinger is set to leave the agency on May 30. The departure of Mersinger, who has served in one of the CFTC’s Republican seats since 2022, opens the way for President Donald Trump to nominate another member to the financial regulator. Rules require that no more than three commissioners belong to the same political party.  Like the Securities and Exchange Commission, the CFTC is one of the significant US financial regulators whose policies impact digital assets. Lawmakers in Congress are currently working to pass a market structure bill to clarify the roles each agency could take in overseeing and regulating crypto. This is a developing story, and further information will be added as it becomes available.
    The facet of TradFi most ripe for disruption is equities
    Opinion by: Mike Cahill, co-founder and CEO of Douro Labs Despite the institutional frenzy around crypto and the ubiquitous narrative of democratized access to investing, most of the world population is still barred from traditional wealth-building.  Take the US, for example — here, the top 10% of earners own more than 90% of all stocks. On a global scale, it gets even worse: Billions of individuals don’t have the financial literacy, digital tools or minimum funds required to even access the most basic investment opportunities.  Traditional institutions must do more than just invest in crypto to ameliorate this disparity — they must start employing digital assets for new use cases altogether.  The facet of TradFi that is most ripe for disruption is equities.

    Ethereum retakes 10% market share, but ETH bulls shouldn't celebrate yet
    Key takeaways: Ethereum’s market dominance has hit overbought RSI levels not seen since May 2021, historically followed by major pullbacks. ETH/USD is showing a bearish divergence on the four-hour chart, hinting at a potential 10–15% price correction. Despite the near-term risks, some analysts view a pullback as a “buy-the-dip” setup before a possible move toward $3,500–$3,800. Ether (ETH) has surged over 50% month-to-date in May, vastly outperforming the broader crypto market’s 15.25% gain. The rally has pushed Ethereum’s market dominance (ETH.D) toward the critical 10% threshold for the first time since March. But the rising dominance accompanies signs of overheating, indicating that Ethereum bulls should not celebrate the rally just yet. Ether’s RSI most overextended since May 2021 …

    Ex-SEC Chair Gary Gensler privately supported crypto — McHenry

While the project claims to protect user privacy in the age of proliferating AI, it’s faced a slew of regulatory concerns across the globe. Formerly known as “Worldcoin,” the iris-scanning technology and its crypto token payout scheme are being probed by authorities in India, South Korea, Italy, Colombia, Argentina, Portugal, Kenya and Indonesia. In Spain, Hong Kong and Brazil, it’s outright banned. World’s latest foray into the US could prove to be CEO Sam Altman’s biggest challenge…
    Crypto VC deals drop in Q1, but funding more than doubles: PitchBook
    Crypto venture capital deals in the first quarter of 2025 saw deal values jump even as the number of deals sank from the same quarter a year ago, says PitchBook. The venture research firm said in its May 14 Crypto VC Trends report for Q1 that 405 deals were made in the quarter, down 39.5% from the 670 deals made in Q1 2024, but slightly up from the 372 made in Q4 last year. However, the total value of deals in Q1 more than doubled from a year ago, jumping to $6 billion compared to $2.6 billion in the first quarter of 2024 and doubling from $3 billion in Q4 2024. PitchBook's senior crypto research analyst Robert Le said that despite macroeconomic turmoil over the quarter, “capital continued to seek crypto’s core utility rails.” VCs poured nearly $2.55 billion across 16 deals into businesses…
    Crypto swapper eXch shows signs of life after post-Bybit shutdown
    Once a go-to swapper for hackers and drainers, eXch was shut down by German police in April — but continued activity suggests the story isn’t over. Without Know Your Customer (KYC) checks, eXch wasn’t your typical crypto exchange. It acted more like an instant swapper, allowing bad actors and cybercriminals to fly under the radar for years. Among its clients was the Lazarus Group. The North Korean state-backed hacking unit thrust eXch into the spotlight back in February, when it used the platform to funnel some of the $1.4 billion it stole from Bybit. When Bybit traced its stolen funds to eXch, it requested assistance — but the platform refused. This led to a fierce discussion over privacy versus security, but ultimately, eXch announced it would close its doors on April 17; on April 30, Ge…

    Synthetix makes $27M bid to re-acquire crypto options platform Derive
    Decentralized finance platform Synthetix is planning to venture further into crypto derivatives with plans to re-acquire the crypto options platform Derive. Synthetix said in a May 14 blog post that it plans to acquire Derive in a token exchange deal, pricing 1 SNX token to 27 DRV tokens, which would value Derive at around $27 million.  The transaction is subject to approval from both the Synthetix and Derive communities, which will take a vote on the proposal, called SIP-415, next week. If approved, the acquisition will combine Derive’s front-end and real-world asset (RWA) expertise with Synthetix’s derivatives infrastructure.

    Thailand to tokenize $150M government bonds for retail investors: Report
    Thailand’s Ministry of Finance reportedly plans to issue $150 million worth of digital investment tokens, allowing retail investors to buy government bonds. The Bangkok Post reported on May 13 that Finance Minister Pichai Chunhavajira announced the initiative at a briefing after the cabinet endorsed the plan. He added that the tokens will be launched within the next two months. The so-called “G-tokens” will be used to raise funds from the public under the current budget borrowing plan, said Patchara Anuntasilpa, director-general of the Public Debt Management Office. He added that these were not debt instruments. “One big selling point of the token is that it allows more retail investors to become part of the digital economy,” he said, adding that for as little as $3, “they can invest in go…

    A Colorado-incorporated firm has been linked to a Chinese illicit marketplace that has served scammers in Southeast Asia and has been used to channel billions of dollars worth of crypto.

A brazen attempt to kidnap the daughter and grandson of Pierre Noizat, the co-founder and CEO of French crypto exchange Paymium, was foiled after the daughter and passersby reportedly fought off the kidnappers.

    What are Linkage Types in C Translation Units?
    Understanding Linkage in C When diving into the concepts of storage classes in C programming, one can encounter the term linkage. At first, it may seem daunting, especially when navigating various technical terms like current translation unit, other translation units, same translation unit, and all translation units. In this article, we'll break down these terms to help clarify their meanings and significance in the realm of C programming. What is a Translation Unit? Before we discuss linkage, let’s establish what a translation unit is. A translation unit consists of the source code after the preprocessor has completed its task. This includes the original .c file and any header files or included modules that are brought in during the preprocessing phase. Essentially, when you compile a sou…  ( 5 min )
    Pioneering a New Era of AI Innovation
    Imagine standing at the threshold of a technological revolution so vast, it could redefine an entire continent's place in global innovation.

    Real-Time Monitoring of Laser Lipo Output via Python or Node.js
    Ever try to monitor a laser system in real-time... with Excel? Yeah, I’ve been there. A couple years ago, I was asked to build a dashboard for a medspa’s laser lipo machine. They wanted live data. Not just logging—but pulse-by-pulse, second-by-second monitoring. My first thought? “This is gonna be a nightmare.” You’d think there’d be some ready-made solution, especially in places as tech-savvy as a Medspa in Chicago. But nope. At first, we tried to jury-rig a CSV parser that pulled in log files every 10 minutes. Huge mistake. We missed surges in energy output, and one day the machine overheated mid-session. That’s when it hit me: we needed true real-time telemetry. Enter: Node.js (or Python, if that’s your jam). Here’s the quick-and-dirty framework I came up with: Stream the machine’s da…  ( 4 min )

It started off simple. Then got frustrating. Then got cool. Then very frustrating. Then… actually awesome. If you’re ready to go from “I think I understand Docker…” to “I just built a full web server from scratch using Docker”, then this one’s for you. Let’s dive in. Docker is a tool that allows developers to package applications and all their dependencies into lightweight, portable containers. Why should you care? Because: It works everywhere (local, staging, prod). You avoid the classic “wo…  ( 6 min )

    Create JavaScript Dynamic List (Step-by-Step Guide)
    A dynamic list updates based on user actions like adding, removing, or editing items. In this tutorial, you'll learn how to create a dynamic list using HTML, CSS, and JavaScript. Basic knowledge of HTML, CSS, and JavaScript A code editor (like VS Code) A browser for testing Create a basic HTML file: Dynamic List ul { padding-left: 20px; } li { margin-bottom: 5px; } button { margin-left: 10px; } Dynamic List Add Create a file named script.js and add the following code: function addItem() { const input = document.getElementById('itemInput'); const value = input.value.trim(); if (value === '') return; const li = document.createElement('li'); li.textContent = value; const removeBtn = document.createElement('button'); removeBtn.textContent = 'Remove'; removeBtn.onclick = function () { li.remove(); }; li.appendChild(removeBtn); document.getElementById('itemList').appendChild(li); input.value = ''; input.focus(); } How It Works? The user types a value in the input field. When the Add button is clicked, addItem() runs. It creates a new with the input text and a "Remove" button. Clicking "Remove" deletes that item. Here is the full example in JSFiddle. You now have a simple dynamic list using JavaScript. You can improve it by saving items to localStorage, adding edit buttons, or using frameworks like React for complex UIs.  ( 3 min )

    Can You Determine Modular Arithmetic in C++ Without Comparison?
    When performing arithmetic with unsigned types in C++, especially with types like std::uint8_t, it's common to encounter questions surrounding modular arithmetic behavior. Specifically, many developers wonder if they can detect when a subtraction operation underflows (i.e., wraps around) without explicitly comparing the two operands. Understanding Subtraction with Unsigned Types In C++, when subtracting one unsigned integer from another, the result is constrained within the limits of the type. For std::uint8_t, this means that values wrap around when the result would go below zero. For example, subtracting 5 from 3 results in 254 due to the wrapping behavior inherent in unsigned types. To validate whether an underflow occurred during subtraction, comparisons are typically used. However, th…  ( 5 min )

    SMUGGLER: Sparse Multi-Unit Granular Generative Learning with Error Resistance
    Abstract This paper introduces SMUGGLER, a novel neural architecture for direct byte-level text generation with remarkable efficiency and error tolerance. Unlike conventional token-based language models, SMUGGLER operates on raw 32-bit character chunks using three innovative mechanisms: 1) Temperature-controlled sparse voter ensembles, 2) Prime-numbered multi-channel parity correction, and 3) RLHF-GAN adversarial training with multiple specialized discriminators. SMUGGLER achieves high-quality text generation with orders of magnitude fewer parameters than traditional approaches while demonstrating resistance to catastrophic forgetting. Experimental results on Shakespeare text generation show that our approach enables efficient, high-quality generation on consumer hardware without requiri…  ( 13 min )
    Built an AI Assistant to Summarize and Query My Emails – Seeking Feedback
    Hey everyone, I recently developed an open-source tool called Email RAG Assistant to help manage and make sense of my overflowing inbox.

    A Inteligência Artificial Generativa não ameaça empregos. Ela ameaça estruturas empresariais obsoletas.
    Muito já se discutiu sobre as funcionalidades da IA Generativa: modelos de linguagem, engenharia de prompts, automação de conteúdo. Mas o verdadeiro ponto de inflexão não está na tecnologia em si — e sim na sua capacidade de subverter modelos de operação que antes pareciam inquestionáveis. Não se trata mais de "adotar IA" como ferramenta, mas de compreender a IA como um agente de transformação organizacional. Alguns sinais são evidentes: Propostas comerciais que levavam horas para serem montadas agora podem ser redigidas em minutos, com base em dados contextuais e históricos de negociação. Campanhas de marketing não precisam mais ser montadas do zero: são concebidas, testadas e ajustadas por sistemas autônomos com base em comportamento e intenção. A IA Generativa não está apenas automatizando processos. E, talvez mais importante: está alterando o que esperamos das organizações e dos profissionais que nelas atuam. O risco real não é ser substituído pela IA. Não é mais suficiente usar IA. A pergunta, então, não é mais “como aplicar essa tecnologia?”. Sua organização está preparada para repensar seus fundamentos operacionais à luz da Inteligência Artificial Generativa — ou será refém de sua própria inércia? 📌 O debate precisa sair do nível técnico e alcançar o nível estratégico. A IA Generativa não é uma revolução do como. É uma disrupção do por que e para quem as coisas são feitas.  ( 3 min )
    Choosing a Cloud Provider? Here’s Why It’s More Than Just a Price Tag
    In a world where digital transformation is no longer optional, choosing the right cloud provider is one of the most strategic decisions a business can make. But here’s the kicker — most businesses compare providers solely based on cost or brand name. And that’s where they go wrong. AWS has the widest range of services, but are you using them efficiently? Azure integrates deeply with Microsoft products, but is that always an advantage? Google Cloud boasts AI and data capabilities, but what if your use case doesn’t need it? If you’ve ever asked: “Which cloud is the best?” “What’s the real difference between AWS, Azure, and GCP?” “Which provider is right for my workload?” … you’re not alone. We’ve seen startups and even large enterprises spend weeks debating, only to realize they missed core decision criteria. Here’s what often gets overlooked: Compliance & Governance: Which cloud helps you stay audit-ready with less manual overhead? Hidden Cost Models: Are you aware of ingress/egress charges and region-based billing quirks? Developer Experience: How fast can your team get up and running with a new toolset? Multi-Cloud or Vendor Lock-in? Should you optimize for performance, flexibility, or both? These questions aren’t just technical. They’re deeply tied to your business strategy and long-term scalability.

    Do I Need to Use CASE in SQL WHERE Clause Too?
    When working with SQL, one of the common inquiries developers face is whether the CASE statement in their SELECT clause effectively filters records or if they also need to replicate the same conditions in the WHERE clause. This question is particularly pertinent when grouping certain entries, such as teams, and seeking clarity on how SQL evaluates these expressions. Understanding SQL CASE and WHERE Clauses The CASE statement is primarily used to create conditional logic inside your SQL queries, particularly in the SELECT clause. Its purpose is to return specific values based on the conditions you define. However, the WHERE clause serves a different function; it limits the rows returned by the query based on certain conditions. Why You Might Need Both CASE and WHERE In your specific example…  ( 4 min )

    Automatic tag deletion for Docker registries
    Introduction Docker registries are essential nowadays in a world of containerized workloads. Want to run your app on Kubernetes? You need to push it to a registry first. If you don't want to pay for a managed, private registry service, you self-host your own. The biggest pain point of Docker registries is storage. If you choose to store registry data on a local disk, you are limited by capacity. Over time, registries accumulate a lot of garbage in the form of blobs referenced by old images that are not needed anymore. Many registry implementations, such as CNCF Distribution, offer garbage-collection mechanisms to delete unreferenced blobs and free up storage space. However, for that to happen, old images (tags) referencing them have to be deleted first. There are implementations like Har…  ( 4 min )

    Why Coordinating Microservice Changes Is Still a Mess
    Read this article on Signadot. Testing in-progress changes together, across services, without merging early or coordinating a full rollout, shouldn’t be so painful. “Hey, don’t merge that yet, I still need to test with my service.” Sound familiar? Coordinating changes across microservices during feature development always starts simple. When your whole stack fits in a single repo or an EC2 box, it’s not a big deal. But fast-forward a bit, and you’re juggling 20, 40, maybe hundreds of services owned by different teams, moving on different timelines, and depending on each other in subtle, undocumented ways.

    Write Once, Deploy Everywhere (Almost)
    As a developer, my core expertise lies in frontend and mobile app development using React Native. Given that both frontend and React Native leverage JavaScript, I've explored cross-platform solutions like react-native-web. However, this approach often means sacrificing certain advantages inherent to each platform, such as straightforward CSS styling or enhanced SEO capabilities. In my frontend work, I also utilize a range of technologies tailored to specific client needs, including Astro.js, React, Next.js, or even vanilla HTML, CSS, and JavaScript. This often leads me to the fundamental question: how can we write code once and deploy it across web, Android, and iOS while maintaining excellent design, SEO, and performance? My current answer points towards the power of Artificial Intelligen…  ( 3 min )
    React got me hired, Vue made me better
    When I started learning FE, I began with React - like many others. It's the most popular library, and if you search for job opportunities there are abundant. And at that stage, you should have only one goal/priority, getting hired and gaining experience. So it's only reasonable to start with React. I learned React through class component, and yes, they are deprecated. But understanding gave me deeper grasp of how React works under the hood (lifecycle methods, binding, rendering). Eventually, I landed my first job working on Vue project. It wasn't a conscious shift, but it was a opportunity. Over time I came to appreciate Vue, and while writing this, I feel like a need to promote it. Especially through lens of someone who also mentored new developers in React, on bootcamp.

    Um desabafo sincero
    E talvez você se identifique... Desde 2023 venho trabalhando como dev profissionalmente. Sempre fui o tipo de dev "raiz", que gostava de codar, passar horas (ou noites inteiras) imerso em projetos que nem eram meus. Saí de outro estado pra Natal-RN com a cara e a coragem. Aluguei um canto só com a roupa do corpo e fui construindo meu espaço — e finalmente, trabalhando como dev. Amava o que fazia. Mas com o tempo, o cenário mudou. A inflação subindo, custo de vida aumentando, e meu salário... estagnado. A vontade de procurar empregos melhores chegou, deu certo, o salário subiu... etc. Mas há alguns meses, no fim de 2024, percebi que tinha perdido o amor pela programação. O código virou só uma moeda de troca. Eu só queria o dinheiro. E aí veio o maior problema: ❌ Não me atualizei ❌ Fiquei pra trás ❌ Acabei o último contrato PJ e tive uma dificuldade ENORME pra me realocar Enquanto devs realmente bons escolhem onde querem trabalhar, eu tava no limbo, tendo que dar vários passos pra trás. A pergunta martelava: “O que tem de errado comigo?” Depois de muito pensar (e muita autoanálise), percebi: Eu tinha perdido meu lado dev raiz. Aquele que curte aprender, codar por prazer, mergulhar nos porquês das coisas. Tava tudo no automático. Então, comecei do zero de novo. Voltei pro básico: codando, lendo, contribuindo, errando, aprendendo. Dessa vez com prazer. E percebi que tinha me desviado do meu caminho. Antes de olhar pra vaga, eu perguntava: “Quanto paga?” Se não fosse "bom o bastante", eu nem tentava. Agora, a primeira pergunta é outra: “O que posso aprender aqui?” Voltei a contribuir, voltei a movimentar meu GitHub, voltei a fazer parte da bolha dev disso que eu gosto, que eu sempre sonhei, e de onde eu simplesmente me perdi. E aí? Você ainda é dev, DEV? Ou tá só no piloto automático?  ( 3 min )

    I Built a New Programming Language for Neurodivergent Creators — Meet Sona
    Why I Built Sona Modern programming languages weren’t built with neurodivergent or first-time coders in mind. That’s a gap I couldn’t ignore. As a self-taught developer, I spent years battling syntax errors, inconsistent tooling, and steep learning curves — not because I lacked motivation, but because the language design just wasn't made for brains like mine. So I built Sona — an open-source programming language designed to simplify coding, reduce friction, and empower creativity. What Makes Sona Unique? Minimal, readable syntax (inspired by Python, Rust, and Go) REPL-first development (Sona v0.4.3 just launched!) Modules that feel native and expressive (import fs, stdin.input(), etc.) Designed for focus + accessibility, including neurodivergent users Fully open-source, interpreter built with Python + Lark Current Progress ✅ Interpreter up to v0.4.3 ✅ 12+ core modules complete (fs, http, json, env, stdin, etc.) ✅ REPL mode: multiline function support, :env commands, graceful errors ✅ Preparing for public alpha (v1.0) Call to Action This is your invitation to help shape the future of dev tooling. 👉 Try Sona.

    DevLog 20250512 Visual Novel Game Framework (Highlights)
    When set to imagine practical, easy-to-use, lightweight applications of Divooka, a visual novel game framework is one of those that came to mind. Visual novels should be such a straightforward type of application to build, yet surprisingly, it's not generally easy to find ready-to-use tools available for them. Of course, one can use Defold, Godot, Unity 3D, or even Unreal to build such a game — or the more technically inclined might just use SFML or other lower-level graphics libraries. Still, it's a lot of work to get a conceptually straightforward task done. Much like building an LLM agent or chaining different AI services together — it's straightforward, it's visual, it describes some kind of workflow or dataflow — then it's a good fit for Divooka. Visual novels fundamentally consist of…  ( 4 min )
    How to Push an Object to a MongoDB Array in TypeScript?
    If you're transitioning from JavaScript to TypeScript, you may encounter type-related issues that can be frustrating. In this article, we'll delve into how to properly push an object into a MongoDB array using TypeScript and address common errors you may face in the process. Understanding the Error Your current error occurs because TypeScript is more strict with types compared to JavaScript. The error message you’re experiencing: Type '{ answers: {}; }' is not assignable to type 'PushOperator'. This suggests that TypeScript expects a specific type for the answers field, but you are passing an empty object {}, which doesn't match the expected type. Setting Up Type Definitions To resolve this, you need to define the type of the answers array properly. Assuming that answerObj represents the …  ( 4 min )
    Compiled Programming Language- Part1 (Compiler)

[Source Code] → (Compiler) → [Machine Code] → [Executable File] [Executable File] → (CPU executes) → Program runs _Source Code _ :- A programmer writes a code, which is called human readable language. Compiler :- A special program, the compiler, takes the source code as input. Analogy Machine Code :- Compiler translates the source code into manchineel code, which is a set of instruction the CPU can understand. Executable file A structured file format (like .exe, .out, .elf etc) that contains: Machine Code Metadata (like symbol tables, headers, memory layout) This is the final output produced by the compiler.

    Stepping Aside to Lead in Tech
    We are living in an exciting era for software development. It has always been an industry of constant evolution, but the rise of artificial intelligence has multiplied the productivity of those who adopted it early. This new reality, with teams capable of building faster than ever, shines a light on something many leaders still don't want to see: the main bottlenecks are often not in development, but in how we manage processes and make decisions. When developers become more efficient, tasks are delivered faster, and AI tools can automate or accelerate repetitive work, the real obstacles are exposed: unnecessary processes, unproductive meetings, outdated hierarchies, and a constant need to “feel in control.” All of this slows teams down.

    ⏱️ Solana’s Proof of History (PoH) — The Clock That Powers the World’s Fastest Blockchain
    Solana has made a name for itself in the blockchain space as one of the fastest and most scalable platforms in the industry. But what’s the secret behind its speed? It all starts with time. More specifically — Proof of History (PoH). In this blog post, we’ll break down what PoH is, how it works, and how it helps Solana achieve high throughput, low latency, and fast finality — all in a way both beginners and developers can understand. In most blockchains (like Bitcoin or Ethereum), time is a vague concept. Each block is timestamped by validators or miners — but there’s no standardized clock. This creates a challenge when trying to organize transactions quickly and securely. Nodes must constantly communicate to agree on order, which slows everything down. 🧠 Enter Proof of History: Time Befo…  ( 4 min )
    The Modern Frontend Fantasy is Falling Apart – Astro, Qwik, and Solid Aren’t the Future
    They promised speed, simplicity, and a better DX. What we got was a set of beautiful lies, niche fantasies, and philosophical dead ends. Modern frontend frameworks love to sell a dream. Let’s talk about the three self-proclaimed rebels of modern frontend: Astro — The Gatsby Ghost in Island Clothing Qwik — The Resumable Kernel That Forgot the Humans Solid — The Signal Soloist in React's Orchestra Together, they form the Zukkoke Three — each chasing a different ideal, but none equipped to win the war. Astro sells the fantasy of zero-JS by default. Clean HTML. Minimal payloads. Islands of interactivity. Astro is just Gatsby rebranded. It inherits the same flaw: It works great until your app grows. Then you’re back to hydrating islands, shipping frameworks, and juggling scripts. Astro’s true n…  ( 6 min )

    How I Code Fast with AI and Still Own the Result
    My AI-Driven Coding Workflow: Fast, Dirty, Smart For years, I’ve followed a simple, effective development rhythm: Refactor the existing code to make space for what’s coming.

The last few years have made AI coding assistants usable, stable, and practical. So I’ve adapted my process. Here's how it looks today: Start with a clean working tree. No changes, no mess. This has always been good practice, but it’s critical now. Why? Because AI can (and will) generate garbage. If it does, you need to scrap everything fast. You can’t "undo" AI-generated logic.

    Programming language of the future Part 4: Distributed Actors
    A good programming language should model it's domain in the most straight-forward way - that way there are no rough edges, no friction. The programmer has no gotchas to work around, the code flows naturally. Distributed programming in modern mainstream languages is not that experience, and in this blog we will go over a part of the solution, the one having to do with coordination of distributed actors. OOP models a program as an interaction between objects, and its implementation in most modern languages work well in a single-threaded context. But as soon as concurrency gets introduced - you either introduce a whole different mechanism than the objects you've been building with up til this point (threads and mutexes and thread-local variables), or an event loop, and a split in the laguage …  ( 7 min )
    Sharing Pages Drop: A Free Platform for Web Deployment and File Sharing
    When you need to deploy a simple HTML page (like one generated by AI), or quickly share some design drafts, or deploy a small website from a ZIP package, what tools do you usually use?

It's essentially a place for hosting and sharing files, and crucially, it's completely free and very convenient to use. Why do I think it's worth sharing? Mainly for these reasons: Although there are similar products, such as Tiinyhost, Static App, etc., the free plans have very few resources and are very restrictive. The free tier is quite generous: Completely Free: The core features are genuinely free to use. Unlimited File Upl…  ( 4 min )

    Working with API Rate Limits: Lessons from Developer Mistakes
    Hello Dev.to readers! This time, we decided to adopt a slightly more serious tone and tackle a serious topic. In our New Gen Atari project, we hit rate limits hard. After that mess, we finally turned to the documentation. To keep you from falling into the same trap, I wanted to write a piece with above-average seriousness. API rate limits cap the number of requests you can make to an API in a given timeframe (e.g., 100 requests per minute). Exceeding these limits results in rejected requests, disrupting your application. They’re standard across platforms, whether free or paid tiers. Limits serve three key purposes: Security: Protect servers from malicious request floods. Resource Management: Ensure fair access for all users. Cost Control: Prevent excessive server resource consumption. Igno…  ( 5 min )

    My Favorite Home Assistant Automation: Waking Up to the Smell of Coffee ☕️
    I recently set up Home Assistant and started exploring the world of smart home automation. One of my first—and now favorite—automations is part of my morning routine. Let’s be honest: waking up early sucks. Alarm clocks are loud, annoying, and stressful. I wanted something more peaceful to get me out of bed. And I found it… I wake up through the smell of coffee and the gentle bubbling sound of a moka pot. 😌 I bought this moka machine from Bialetti: https://www.bialetti.com/ee_en/moka-elettrika.html It’s called the Moka Elettrika, and it runs on electricity. I connected it to a smart plug that’s controlled by Home Assistant. At 7:55 AM, the smart plug turns on, powering the moka pot. The moka starts brewing right away. At 8:10 AM, the plug turns off again. By the time I'm awake, the apartment smells like fresh coffee, and I hear that cozy, comforting moka pot bubbling away. It’s such a calm and natural way to wake up—no loud noises, no stress. This tiny automation has made a huge difference in how I start my day. If you're into smart home stuff (or just love coffee), give it a try!  ( 3 min )

    Why Technical Interviews Feel Broken - and How to Stop Failing Them
    There’s a strange paradox in tech: someone can be a solid developer, lead projects, write clean code, and still fail interview after interview. Not once, but over and over again. And we’re not talking about juniors. I’ve seen senior engineers freeze mid-sentence, forget terminology, or just walk away feeling like they bombed, even though they knew the answers. If that sounds familiar, you’re not alone. I’ve worked with developers for years: hiring them, preparing them, evaluating them. And here’s the truth: if you’re struggling with interviews, it doesn’t mean you're unqualified. It means the format is broken. In theory, a technical interview checks if you know your stuff. In reality, it’s a pressure cooker. Here’s what it throws at you: limited time unfamiliar phrasing of questions z…  ( 4 min )

    How to Fix Rust Compilation Error When Reading Tokens from File
    Introduction In Rust, handling files and processing their content efficiently is crucial, especially when dealing with potentially large files. A common scenario involves reading lines from a file and splitting those lines into individual tokens based on whitespace. However, you might encounter a compilation error due to how Rust handles lifetimes and references. In this article, we will explore the origin of this issue and provide a solution that returns an iterator of owned String values without allocating too much memory upfront. Understanding the Compilation Error When you attempt to return a value that references function parameters, Rust will flag this as an error. Your original code attempts to utilize the .split_whitespace() method, which returns slices of the original string. The …  ( 4 min )

    Google Got Fined $1.4 Billion for Data Abuse, So Here’s What Devs Should Be Auditing
    Google just paid $1.375 billion to Texas for secretly tracking users, collecting geolocation, voiceprints, and facial recognition data even with privacy settings disabled. The headlines scream “Big Tech scandal” — but here’s the real message: If your app handles user data, you’re part of this conversation. And if you’re using tools like Firebase, Google Analytics, or Meta Pixel in production without understanding what’s being captured, you’re one misconfigured SDK away from a privacy disaster. 🔍 So, What Should Developers Do? Re-check what your analytics are logging. Google Analytics 4 tracks more than you think by default, especially if you’ve enabled Enhanced Measurement. Alternative: Try Plausible or PostHog. They’re privacy-first, self-hostable, and GDPR-compliant. Audit your use of location data. If you’re using React Native Geolocation, are you requesting location only when needed? In web apps, check the navigator. Geolocation calls, are you storing or sharing that info? Facial recognition libraries? Tread carefully. Read your dependencies’ privacy policies. Cookies and localStorage: keep them clean. Use libraries like cookie-consent and tools like Cookiemonster.dev to flag risky behavior early. 🧠 The Bottom Line As devs, we build the foundation of user experiences, and that includes privacy-first defaults. Not because it’s trendy, but because it’s now a requirement.  ( 3 min )

This can be frustrating as you're working with your Dart code. In this article, we'll explore potential reasons behind this problem and how to fix it effectively. Why Are Errors Not Showing Up in Android Studio? Dart is a language that uses a strong type system, which means it usually identifies errors during development. If errors are not appearing, there are a few possible causes: IDE Configurations: Sometimes, after an update, settings may return to defaults or change unexpectedly. Project Settings: Your project configuration might not be set up correctly for error detection. Dart and Flutter SDK: Issues with the SDK installa…  ( 5 min )

    Setting Feedback Up for Success — Before the Conversation Even Starts
    When we talk about giving feedback, most of the advice out there focuses on how to say the thing. But what I have learned over time is that the real magic happens before the conversation even starts. Setting the stage can be the difference between feedback landing as a gift or feeling like an attack. Some of the most effective feedback conversations I have had - both from giving and receiving - actually started with a letter. When there's a lot to say, taking the time to write it down helps in more ways than one. It lets you rewrite, refine, and make sure the message you intend is the message that gets carried forward. You can catch moments where your tone might be too harsh, or where you're speaking from frustration instead of clarity. From the recipient's perspective, it's a game-change…  ( 4 min )
    Registering callback using std::function in C++
    Welcome to the next pikoTutorial ! Imagine you're building an application that processes some data and once it's done, the user needs to be notified about the result. Since you don’t want to hard-code the notification logic, it’s better to allow the user to register a custom function that will be called automatically after the data processing completes. std::function for callback registration One of the most flexible ways to implement callbacks in C++ is by using std::function. std::function can store and invoke any callable object (functions, lambdas, or function objects) that matches a specific signature. The overall syntax is: std::function name; Let’s define a ProcessData unction that accepts a callback and notifies the user once processing is complete. #include #include // Type alias for the callback type using CallbackType = std::function; // Function accepting callback as an argument void ProcessData(const CallbackType& callback) { // Simulate data processing std::cout << "Processing data" << std::endl; // Notify user via callback callback(true); } // Callback function definition void Callback(const bool result) { std::cout << "Callback called! Result: " << result << std::endl; } int main() { // Register a callback using an existing function ProcessData(Callback); // Register a callback using lambda function ProcessData([](const bool result) { std::cout << "Lambda called! Result: " << result << std::endl; }); // Register using callable object CallbackType cb = [](const bool result){ std::cout << "Callable called! Result: " << result << std::endl; }; ProcessData(cb); }  ( 3 min )
    The Soul of the Keyboard: A Brief History of WASD Keycaps
    In the world of keyboards, the WASD keycaps hold a special place. These four simple letters—W, A, S, and D—are often seen as the backbone of gaming. For most gamers, they’re more than just letters on a keyboard; they’re the foundation for movement in the virtual worlds they explore. But like all great inventions, the history of WASD keycaps goes beyond their initial function, evolving to become a symbol of gaming culture and a feature beloved by enthusiasts. Let’s take a journey through time to uncover the origins, evolution, and significance of WASD keycaps. The WASD layout, used predominantly in first-person shooters (FPS) and other action games, has become almost synonymous with gaming itself. But where did it come from? Originally, keyboards were designed with the arrow keys or the num…  ( 6 min )

    7 Underrated JavaScript Tricks That Will Make You a Better Developer
    🔍 Introduction JavaScript is packed with powerful features—but many developers stick to the basics and miss out on time-saving gems. In this post, I’ll show you 7 underrated tricks that can simplify your code, enhance readability, and make you look like a JavaScript pro in 2025. ?. const username = user?.profile?.name || 'Anonymous'; ✅ Avoids errors when deeply nested properties are undefined. Cleaner and safer than long logical chains. ?? const count = inputValue ?? 0; ✅ Returns default only if the left-hand value is null or undefined (unlike ||, which includes 0 or ''). const { title: blogTitle } = post; ✅ Grab and rename properties in one line. const isAvailable = !!value; ✅ Quickly turn any truthy/falsy value into a clean true or false. const user = { name, age }; // same as { name: name, age: age } ✅ Reduces repetition when property and variable names match. const key = 'theme'; const settings = { [key]: 'dark' }; ✅ Build flexible objects based on runtime values. const status = `You are ${loggedIn ? 'logged in' : 'logged out'}.`; ✅ Great for short conditional strings and UI feedback. These tricks may be small, but they add up to cleaner, more elegant JavaScript code. Whether you're working on a side project, fixing bugs, or building production apps—mastering these patterns will level up your skills. ✅ Try using at least 2 of these in your next app! 💬 Got a trick of your own?

    Should you join a community to learn Rust?
    Short answer: yes Over the past 5 years, I've learned a lot about communities. I've made many mistakes: I could probably create a 'Community Mistakes 101' crash course! Unfortunately, they didn't teach that in high school, which would have been useful. I learned that a community absolutely must have a specific goal. I also learned that while having an open community is good at the beginning, it becomes nearly impossible to handle and moderate long-term unless you dedicate an insane amount of time to it (trust me, I tried) or you are a bored millionaire lying on the couch all day (which is not my case). Regarding promotion, I've made the mistake in the past of overpromoting communities I created, simply because I was overjoyed about the new adventure. I now think this approach is wrong. it's better if people discover the community on their own. But now I really feel I am ready to do it right. So, why am I writing this? The reason is simple: I've just a new community, and I've decided to use Twitter (sorry, X) for it. The goal is to introduce curious developers to the Rust programming language and help them understand as much as possible. Joining this community is free, just request to join. The link is in my profile, but if you're lazy and want to be invited, just reply below. For now, I am not accepting moderators, but moderators might be chosen from among the active members in the future. Let's Crush it !!!🔥  ( 3 min )
    SSH Error Explained: Permission Denied (publickey) — And How We Solved It 🔐
    When trying to SSH into a newly created Linux server, you might run into a common error like this: $ ssh user@your-server-ip The authenticity of host 'your-server-ip' can't be established. ED25519 key fingerprint is SHA256:xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx. Any other names do not know this key. Are you sure you want to continue connecting (yes/no/[fingerprint])? yes Warning: Permanently added 'your-server-ip' (ED25519) to the list of known hosts. user@your-server-ip: Permission denied (publickey). This error simply means: “SSH couldn’t find a valid key to authenticate you.” ✅ What Actually Worked ssh ubuntu@your-server-ip You used the correct approach by providing the private key file: ssh -i /path/to/your-key.pem ubuntu@your-server-ip And this worked — because the server was expecting authentication via a specific private key (.pem file), not a default key from ~/.ssh/id_rsa. 🔍 Why This Happens key-based authentication only for better security. When you create a VM or instance, you’re often required to either: Upload your public key, or Download a .pem file that matches the server's authorized key If you try to SSH without specifying the .pem file, the SSH client defaults to using standard key files like ~/.ssh/id_rsa, which likely don’t match what the server expects. 🛠️ How to Avoid This in the Future Always specify the key manually with -i OR Add the key to your SSH agent so it's picked up automatically: ssh-add /path/to/your-key.pem 🧠 Pro Tip chmod 600 your-key.pem This keeps your key file secure and prevents SSH from refusing to use it.  ( 3 min )

    How to Pass std::ostringstream Data to API Function in C++
    When working with C++ and interfacing with API functions, developers often encounter the challenge of passing large blocks of data. In your case, you're constructing a large string using std::ostringstream and need to send this data to an API function, API_function, defined as int API_function(const char* data, int len). The issue arises when the data contains null bytes (0x00), resulting in data truncation. Let’s address how to pass this std::ostringstream payload effectively to the API function without copying it, especially in the context of constrained environments like microcontrollers. Understanding the Issue with Null Bytes The problem you're facing is due to the way C-strings (null-terminated strings) work in C++. When you use payload.str().c_str(), you get a pointer to the interna…  ( 5 min )

    [WIP][Godot 4 & Py] BrainsIAAndPixels – 3D PixelArt Game with AI-Controlled NPCs
    Hi everyone, The game is called BrainsIAAndPixels: it's going to be a 3D title with a pixel art style (even though it's set in a 3D environment), where NPCs won't be rigidly "scripted" but will instead be controlled by real artificial intelligence using pre-trained models running locally. The goal is to create a game where NPCs understand and react to what happens around them, rather than just following a fixed pattern. I'm using Python in Godot, and the AI part relies on ONNX models. Right now, I'm setting up the development environment, testing the AI integration, and building the foundations. The plot and genre aren't fully defined yet (I'm torn between survival, something narrative-driven, or similar), so any ideas are more than welcome. Thanks!  ( 3 min )

    Accessibility Testing on Windows on Mac
    Today's note is about something that I, as a new Mac user, had to deal with while setting up my work environment.

    Can You Pass a List of Child Objects to a Parent Function in Java?
    When working with object-oriented programming in Java, it's common to encounter situations where you want to pass a collection of objects from a subclass (child) to a method that expects a collection of objects from a superclass (parent). This might seem straightforward, but the compilation error you're facing highlights a key aspect of Java's type system, particularly with generics. Understanding Java Generics Generics in Java provide a way to specify a type parameter when defining classes and methods. When you declare a method that takes a list of a specific type, such as List, it expects a list that strictly contains Parent objects, not Child objects. Even though Child is a subclass of Parent, List is not considered a subtype of List. This is due to Java's type sa…  ( 5 min )

    How to Cross-Compile Go Applications for ARM64 with CGO_ENABLED=1
    Introduction If you're developing Go applications and want to run them on ARM64 architecture, especially within environments like AWS Lambda, cross-compiling can be a bit tricky, particularly when you involve CGO. In this guide, I'll walk you through the process of cross-compiling your Go application with CGO_ENABLED=1, targeting ARM64 architecture from an AMD64 Jenkins agent. Understanding the Need for Cross-Compilation Cross-compiling is essential when you're developing applications on a different architecture than the one they're intended to run on. For instance, you might be developing on an AMD64 system (like most PCs) but want your application to run on an ARM64 architecture, such as AWS Lambda functions. Using CGO_ENABLED=1 specifies that you want to enable CGO, which allows Go to c…  ( 5 min )
    MongoDB Views or Materialized Views: When to Use?

    Why You Should Use function_exists in Your PHP Helpers
    In Laravel projects or any large scale PHP application it's common to create helper files that contain reusable functions. These helpers make your code cleaner and more efficient. But there's a common issue, defining the same function more than once will cause a Fatal error.. What's the problem? If the same function is declared twice, PHP will throw an error like this: Fatal error: Cannot redeclare function_name() This often happens because of: Repeated includes: Package conflicts: The safe solution To prevent this issue, wrap your helper functions like this: if (!function_exists('sayHello')) { function sayHello() { return 'Hello!'; } } This way, if the function already exists, PHP will skip redefining it, and your app will keep running smoothly. In Laravel projects Even with Laravel’s powerful autoloading and service container, this pattern is essential. It keeps your project safe from unexpected conflicts and ensures maximum compatibility especially when working with custom helpers or external packages. Summary: function_exists It’s a small thing that can save you from big problems.  ( 3 min )

Understanding the 'No Anonymous Block Parameter' Error In Ruby, when you define a method that takes a block, you generally have to capture that block using a block parameter. The error 'no anonymous block parameter' suggests that the block you're trying to define doesn't have an associated variable to hold the block context. Without this, Ruby cannot process the block correctly, leading to the error. Common Scenario of the Error Let's take a look at t…  ( 4 min )

    US lawmakers call for change in corporate digital asset taxes
    Two US senators are calling on Treasury Secretary Scott Bessent to “exercise [the department’s] authority” and change a provision affecting taxes on corporate holdings of digital assets. In a May 12 letter, Senators Cynthia Lummis and Bernie Moreno suggested Bessent had the authority to change the definition of “adjusted financial statement income” under existing US law in a way that could reduce what digital asset companies pay in taxes. The proposed adjustment was suggested as a way to modify a provision of the Inflation Reduction Act, signed into law in 2022. “Our edge in digital finance is at risk if US companies are taxed more than foreign competitors,” said Lummis in a May 13 X post.

    What are the next steps for the US stablecoin bill?
    Proponents of a bill to regulate stablecoins in the US Congress will likely take up another vote on the legislation in a matter of days without responding to concerns about President Donald Trump’s financial ties to the cryptocurrency industry. The Guiding and Establishing National Innovation for US Stablecoins, or GENIUS Act, failed to get enough votes to pass in the US Senate on May 8 amid calls from some Democratic lawmakers to halt any legislation related to digital assets until Republicans could address Trump’s potential conflicts of interest. Immediately following the vote, some lawmakers from both parties suggested they could reconsider the bill as early as this week, but without agreeing on a bipartisan path forward. After the GENIUS Act failed to proceed in a 48 to 49 vote in the…

    Bitcoin remains unmatched as a global inflation hedge
    Opinion by: Jupiter Zheng, Partner Liquid Fund at HashKey Capital Whenever Bitcoin falls in value, the narrative is always the same: It’s failing as a hedge against inflation. In the eyes of critics, Bitcoin is not the “digital gold” that so many others claim it to be. With gold hitting all-time highs, these critics have grown louder. If Bitcoin is an inflation hedge, they ask, why isn’t it also rallying as investors seek safety? Even in today’s bearish, high-inflation environment, the cardinal truth holds: Bitcoin is an inflation hedge — arguably the most important one for long-term capital preservation the world has seen.  Strength in scarcity Bitcoin has a hard cap of 21 million coins, with full circulation expected by 2140. This built-in scarcity mirrors gold, which has historically se…

Charlie Yechuan Hu, CEO of Bitcoin layer-2 protocol Bitlayer, shared his insights on venture capital (VC) firms in the Bitcoin (BTC) ecosystem. Hu told Cointelegraph that he views many VC firms in the space positively, as they offer support to early ventures that need capital to build infrastructure. “You need developers, you need to open up the whole ecosystem foundation, everything,” Hu said. “You need to pay for the cloud, like AWS or RPCs, all that, servers […] So, we have to have VC on that.“ Hu argued against the usual Bitcoiner ethos that argues against outsider capital, saying,…

    Arizona governor kills two crypto bills, cracks down on Bitcoin ATMs
    Arizona Governor Katie Hobbs vetoed two key cryptocurrency-related bills that aimed to expand the state’s involvement in digital assets while signing a strict regulatory measure targeting Bitcoin ATMs. On May 12, Hobbs rejected Senate Bill 1373, which sought to establish a Digital Assets Strategic Reserve Fund. The fund would have allowed Arizona to hold crypto assets obtained through seizures or legislative allocations. “Current volatility in cryptocurrency markets does not make a prudent fit for general fund dollars,” she stated in her veto letter. “I have already signed legislation this session which allows the state to utilize cryptocurrency without placing general fund dollars at risk,” she added. That decision followed her veto of Senate Bill 1025 — the more ambitious “Arizona Strate…

    Caitlyn Jenner memecoin buyers to regroup after judge tosses suit
    The lawyer for a group of Caitlyn Jenner memecoin buyers said they will continue their legal fight against the ex-Olympian after a judge threw out the case for failing to adequately support the securities and fraud claims it brought. Jenner had escaped a class-action lawsuit from buyers of her self-titled memecoin, Caitlyn Jenner (JENNER) after California District Court Judge Stanley Blumenfeld Jr. said in a motion filed on May 9 that it was “sufficient to conclude that all nine causes of action are deficient” and sided with Jenner in dismissing the suit in its entirety for failure to state a claim. He allowed the class group to amend its suit, which must be filed by May 23, but warned it had “to be more focused and judiciously pleaded” than the original. A lawyer for the class group, Fitz…

His lawsuits forced people into costly and time-consuming legal defenses, often based on fabricated evidence, the judge added as he handed out a General Civil Restraint Order or injunction against Wright, prohibiting him from filing any more civil claims or applications in the High Court.  The court highlighted how this strategy was part of a pattern of abusi…

    The US government has asked a federal judge to impose a two-year sentence for Eric Council Jr., the individual who helped post a fake message announcing the approval of Bitcoin exchange-traded funds through the Securities and Exchange Commission’s (SEC’s) X account. In a May 12 filing in the US District Court for the District of Columbia, prosecutors recommended Judge Amy Berman Jackson sentence Council to two years in prison for his role in posting a message to the social media platform X suggesting that the SEC had approved spot Bitcoin (BTC) exchange-traded funds (ETFs) for the first time in January 2024.

    Bitcoin price sells off after Trump’s US-China tariff deal — Here is why
    Key takeaways: Bitcoin lags as investors shift toward stocks after the US and China strike a deal that could end the current trade war. Macroeconomic conditions are swinging away from gold investing and back to stocks.  Bitcoin (BTC) reached its highest price in over three months at $105,720 on May 12, but was unable to maintain its bullish momentum. Interestingly, the drop to $102,000 came after a temporary easing in the US-China tariff conflict. This has left traders puzzled as to why Bitcoin reacted negatively to what seemed like positive developments. The 90-day truce reduced import tariffs, and US Treasury Secretary Scott Bessent noted that the agreement could be extended, provided there is a genuine effort and constructive dialogue. According to Yahoo Finance, the topics under dis…

    Will Bitcoin hodlers be the reason more countries adopt wealth taxes?
    Opinion by: Robin Singh, CEO of Koinly Is there a catch for Bitcoin hodlers, with the asset’s price up over 600,000% since the beginning of 2013?  Perhaps — if governments keep waking up to Bitcoin’s value, the whole “you only pay tax when you sell” mantra could soon be a thing of the past. What if a wealth tax is the answer for revenue-hungry tax agencies with no time to lose? It’s a yearly tax on a person’s total net worth — cash, investments, property and other assets — minus any debts, applied whether or not those assets are sold or generating income. The idea is to boost public revenue and curb inequality, mainly by taxing the ultra-rich. A wealth tax takes a clip off what you own, not what you earn. Countries such as Belgium, Norway and Switzerland have had wealth taxes baked into th…

We do want trade. We want more balance in trade.” Joint statement on US-…

    What is RISC-V, and why does Vitalik Buterin want it for Ethereum smart contracts?
    What is RISC-V? RISC-V, pronounced “risk five,” is a modern open-source instruction set architecture (ISA) based on reduced instruction set computer (RISC) principles. In simple terms, it’s like a blueprint that defines a set of instructions that a processor can execute. RISC-V is designed to be highly modular, efficient and flexible. Originally developed by the University of California in 2010, the open-source framework gives developers the flexibility to tailor its functionality and use cases, plus offers cost savings compared to proprietary ISAs like ARM or x86. This offers a wide range of uses, from supercomputers to smartphones and now blockchains like Ethereum. On April 20, 2025, Ethereum co-founder Vitalik Buterin unveiled a “radical” new sc…

    Can you stake Bitcoin (BTC)? Here’s what you need to know
    Key takeaways Though Bitcoin doesn’t support native staking, holders can earn yield through centralized lending platforms, Wrapped Bitcoin (WBTC) on Ethereum, and Bitcoin-related networks like Babylon and Stacks.

    Japanese investment firm Metaplanet has added another $129 million to its Bitcoin treasury, pushing its total holdings past the Bitcoin-stacking country of El Salvador.  “Metaplanet now holds more Bitcoin than El Salvador. From humble beginnings to rivaling nation-states, we’re just getting started,” said CEO Simon Gerovich on X after the latest purchase announcement.  On May 12, the Tokyo-listed firm announced that it had acquired 1,241 Bitcoin (BTC) for 14.8 million yen ($101,843) per coin. The total buy, at its highest ever purchase price, is worth around $129 million at current market prices.  This brings the firm’s total holdings to 6,796 Bitcoin, currently worth around $707 million, and the average purchase price is $91,000 per Bitcoin. Metaplanet started its BTC accumulation strateg…
    Trump’s US-China trade deal could shed light on Bitcoin’s use case
    Bitcoin’s potential price reaction to a trade deal between the United States and China could give insights into whether Bitcoin is being used as a safe-haven asset in the current market. Bitcoin (BTC) outperformed stocks and held up “incredibly strong” during a sharp sell-off on stock markets in April, following Donald Trump’s announcement of tariffs on “Liberation Day,” observed crypto trader “Daan Crypto” on May 11. Following its plunge to $75,000 on April 7, Bitcoin recovered strongly to trade 27% higher at around $95,000 by the end of the month. Meanwhile, indexes like the S&P 500 and Nasdaq declined in April.  At the time, people wondered if Bitcoin’s relative strength came from the narrative that countries were using Bitcoin to bypass tariffs. The analyst said the opposite should th…
    Stablecoin bill gets second chance with Northern Mariana lawmakers
    Tinian, a small island in the US territory of the Northern Mariana Islands, could get a second chance at launching a stablecoin after the territory’s Senate voted to override the governor’s earlier veto of its stablecoin bill. On May 9, the Northern Mariana Islands Senate voted 7-1 to override Governor Arnold Palacios' April 11 veto of the bill, which would allow the Tinian local government to issue licenses to internet casinos and includes a provision for the Tinian treasurer to issue, manage and redeem a “Tinian Stable Token.”  The bill will now head to the 20-member Northern Mariana Islands House, which will need a two-thirds majority vote to override the veto and pass the bill into law. If the House is quick to pass the bill, the Tinian government could be in the lead for the first US …
    ‘Dark stablecoins’ could emerge as regulations tighten
    Censorship-resistant “dark stablecoins” could come in increasing demand as governments tighten their oversight of the industry.  Stablecoins have been used for various groups to store assets due to a lack of government interference; however, with regulations pending, that could soon change, Ki Young Ju, CEO of crypto analytics firm CryptoQuant, said in a May 11 X post. “Soon, any stablecoin issued by a country could face strict govt regulation, similar to traditional banks. Transfers might automatically trigger tax collection through smart contracts, and wallets could be frozen or require paperwork based on government rules,” he said. “People who used stablecoins for big international transfers might start looking for censorship-resistant dark stablecoins instead.” On the heels of US Presi…
    Ledger secures Discord after hacker bot tried to steal seed phrases
    Hardware wallet provider Ledger has confirmed its Discord server is secure again after an attacker compromised a moderator’s account to post scam links on May 11 to trick users into revealing their seed phrases on a third-party website. “One of our contracted moderators had their account compromised, which allowed a malicious bot to post scam links in one channel,” Ledger team member Quintin Boatwright wrote on the Ledger Discord server.  “The issue was quickly contained: the compromised account was removed, the bot was deleted, the website was reported, and all relevant permissions were reviewed and secured.” Some members in Ledger’s Discord channel claimed the attacker abused moderator privileges to ban and mute them as they tried to report the breach, possibly slowing Ledger’s reaction.…

    How to Troubleshoot ZK-Proof Generation Issues in Next.js
    Introduction If you're delving into zero-knowledge proofs using Next.js and you've stumbled upon an issue generating zk-proofs, you’re not alone. Many developers encounter challenges when attempting to create zk-proofs with tools like snarkjs. This guide explores a common problem regarding input discrepancies that lead to proof generation failures even when everything seems correct. We'll dive deep into why this might be happening and how to effectively address it. Understanding ZK-Proofs and snarkjs Zero-knowledge proofs (ZKPs) allow one party to prove to another that they know a value without revealing the value itself. The snarkjs library is a popular choice for handling zk-proof generation in JavaScript. It is based on efficient cryptographic schemes, enabling developers to solve com…  ( 5 min )

    Why Your Cloud Strategy Keeps Failing (And How I Fixed It)
    Let’s be honest: most cloud “strategies” I come across aren’t really strategies — they’re glorified lift-and-shifts. On paper, migrating to the cloud promises flexibility, scalability, and cost savings. But in reality? Many organizations just copy their on-prem setup into AWS, Azure, or GCP — and call it done. As someone who’s spent years helping companies build scalable, secure, and cloud-native infrastructure across multi-cloud environments, I’ve seen this mistake over and over. But one project in particular made this painfully clear.

    🧩 Rust vs Solidity: Why Solana Uses Rust — Explained Simply
    Solana and Ethereum are two of the most popular blockchains in the world. But if you look under the hood, you’ll notice they speak different “languages.” Ethereum uses Solidity, while Solana uses Rust. So… what’s the difference? And why does it matter? Let’s break it down in plain English. Think of Solidity and Rust like languages people use to build apps — just like websites are built with HTML or JavaScript. Solidity was created specifically for blockchains — especially Ethereum. It’s simple, beginner-friendly, and looks a bit like JavaScript. Rust is more like the serious, high-performance cousin. It’s used to build powerful software like games, browsers, and now — Solana. One of the biggest problems in crypto? Bugs and hacks. Solidity, while easier to use, has been behind many major De…  ( 4 min )
    Laravel Observer: Its Superpowers in Event Structuring
    What is a Laravel Observer? Observers in Laravel are used to listen for specific events on Eloquent models, such as creating, updating, and deleting records. The main advantage of using them is the ability to delegate the data handling logic to a dedicated class, keeping controllers and models leaner. Imagine you need to perform an action every time a user is created. Instead of writing that logic directly in the controller or the model, you can use an Observer to ensure that the logic is isolated and easier to test. Creating an Observer in Laravel is very simple. Let's take a look at a basic example of an Observer for a User model: php artisan make:observer UserObserver --model=User Open the App\Providers\EventServiceProvider file and register the observer: public function boot() { …  ( 4 min )
    Should we start a podcast interviewing our ex-music-school-classmates?
    I'm thinking about starting a podcast with @blumen where we interview a bunch of somewhat successful / living-their-livelihoods-off-of-music people we went to music school with, and see where they are today. Basically Celebrity Catch Up: Life After I Did That Thing but without the Celebrity and without The Thing. 😬 Typing it out now makes it seem like a pretty bad idea, but I think it could be good information gathering for anyone considering music school or working in music. Plus, it would be amusing for our little cohort of music school grads and a fun way for us to reconnect with some folks. According to music-colleges.com (lol), SUNY Fredonia's music program ranks at #276 (out of 1451 schools they evaluated, so technically in the 20%!!). I imagine a podcast like this about Julliard grads would be much more successful, but those people probably wouldn't have good advice or relatable stories for real, non-prodigious but competent musicians. So far our initial brainstorm has us landing around: 30-45 min max Asking people about: What they studied How much schooling they ended up getting Their most memorable Fredonia experience What they do now Career highlights Career lows How much money they currently make (from music) What their advice would be for anyone pursuing their current career, or the program they studied in school Thoughts?  ( 3 min )
    The Philosophy of Film Editing
    The Editor as a Storyteller: Crafting Meaning Through Cuts Film editing is far more than a technical exercise in arranging images; it is a profound act of storytelling. The editor shapes narrative, rhythm, emotion, and even truth by deciding what the audience sees—and when they see it. This power to construct meaning through selection and sequencing makes the editor an essential co-author of a film’s emotional and intellectual impact. At its core, editing transforms raw footage into a coherent and resonant experience. Through choices in duration, order, and juxtaposition, editors influence how characters are perceived, how themes develop, and how a story unfolds. The emotional arc of a scene—whether tranquil or intense—often hinges more on the cut than the shot itself. Editing allows a f…  ( 6 min )

    How to Resolve Address Bar Update Issues in Windows File Explorer
    Introduction If you're encountering problems with the address bar in Windows File Explorer not updating correctly when navigating through shell namespace extension folders, you're not alone.

In this article, we'll explore the root cause of this issue, an effective workaround, and discuss potential solutions. Understanding the Issue The failure of the address bar to update can be attributed directly to the interaction of Windows Shell and shell namespace extensions. More specifically, the IExplorerPaneVisibility::GetPaneState method has been identified as presenting problems when installed with certain Windows updates, pa…  ( 5 min )

    JavaScript Closure Simplified
    Have you ever wondered how JavaScript functions can "remember" things even after they've finished running? That’s the magic of closures, and today we’ll break it down with a simple use case: building a custom counter function. We’ll touch on key concepts like function factories and state persistence to bring this idea home. Closures: For example, in our counter, a variable count is defined inside makeCounter(). The inner function (the actual counter) uses this variable. Thanks to the closure, the count is not lost when makeCounter() finishes, the counter function still remembers it. Function Factory: One Function, Many Counters Think of makeCounter() as a factory. Every time you call it, it gives you a brand new counter, like a fresh instance with its own private count. Each counter is completely independent. State That Sticks(State Persistence) The beauty of closures is state persistence. Since count is part of the closed-over scope, it keeps its value between function calls. That’s what allows the returned function to keep incrementing the same number, step by step. The key takeaway: even though makeCounter() is finished, the returned function still has access to everything defined inside it. That’s the closure in action, enabling encapsulation, memory, and a clean way to manage state without global variables. Closures aren’t just cool, they’re powerful. Once you understand them, you’ll start seeing them everywhere in JavaScript. And best of all, they make patterns like private counters, once complex, totally natural.  ( 3 min )
    A Simple Framework for Designing User Interfaces (for Solo Devs & Small Teams)
    If you're building a product as a solo dev or part of a small team, you've probably struggled with design. You open Figma. You pick a font. Then a color palette. Then you browse some Dribbble shots. Then you go down a dark hole of animations, blur effects, neumorphism... and suddenly you've spent three hours tweaking gradients but your product still doesn't feel right. Here's the problem: you're thinking about design backwards. Design isn't about how your app looks. It's about what it lets people do and how easily they can do it. That's why I follow a dead simple rule: Design functionality first. Make it beautiful later. Design isn't about how something looks it's about what it lets people do. When you focus on visual details too early, you're decorating an idea that hasn't even proven its…  ( 5 min )
    Hello! 😊
    Hi DEV community! My name is Jo. I am a Digital Designer and Learning Technologist at the University of Leeds with a specialism in UX design and web accessibility. My coding journey started over lockdown when I completed a coding bootcamp with The Coders Guild, learning HTML, CSS, basic JavaScript, bootstrap, and Git. I will be honest, I don't need to use it every day for my career so I did forget some of what I've learnt since then but I have started to pick it back up again! My background is in graphic design so I hope to utilise my knowledge in this field to create more visually stunning web experiences. Currently with the support of my colleague, I help create bespoke web development projects that supplement the learning within our online course portfolio. For me personally, these projects are very basic (and partly supported by ChatGPT) because I am still learning... but I hope to change that! My goal is get to the point where I am much better and more confident in my skills at front-end web development and require less hand-holding. I also want to create diverse interactive experiences to hopefully foster genuine curiosity for the subject matter with our students and engage them with the learning material. Managers are more interested in boosting the reputation of the university, but the most important thing for me is to promote academia and make learning fun! Most of my posts will be misc stuff I've learnt and will probably be written with bad or inefficient code rather than being effective tutorials so please read with caution! Thank you for coming on this coding journey with me! If you'd like to connect, my LinkedIn profile is linked before (I no longer use any other social media platform anymore for my professional presence). I am in the process of coding my own website so be sure to keep a look out for this in due time! LinkedIn: https://www.linkedin.com/in/jolaw233/  ( 3 min )
    Think in Sets: Writing High-Performance SQL the Declarative Way
    “SQL is not about loops—it's about logic. The sooner you let go of procedural thinking, the faster your queries fly.” If you’ve come from a programming background, chances are your instinct is to iterate. But SQL wasn’t designed for that. SQL speaks the language of sets, and when you think in sets, your queries become: Faster More readable Easier to maintain In this article, we’ll compare procedural vs set-based logic with clear examples and best practices. Scenario: Mark all Pending orders as Shipped.

    How to Log Python and Bash Output Chronologically in a File
    When working with Python and Bash scripts, logging output can become cumbersome, especially when you want to preserve the chronological order of the messages. The challenge you’re facing is that output from your Bash script is appearing in the log file before the output from your Python script due to buffering issues. This article will guide you through the best practices for ensuring that all outputs are recorded in the correct order, using file descriptors effectively. Understanding Output Buffering When Python writes output to a log file, it may use buffering, meaning it collects a certain amount of data before writing to the file. Similarly, Bash scripts can exhibit this behavior as well. When subprocesses are called within Python, outputs can arrive in an unpredictable sequence, there…  ( 5 min )
    Implementing a Radically Simple Alternative to Graylog
    Back in 2022, my team and I were working on a service which was printing a fairly sizeable amount of logs from a distributed cluster of 20+ hosts: about 2-3 million log messages per hour in total. We were using Graylog, and querying those logs for an hour was taking no more than 1-3 seconds, so it was pretty quick. Infra people hated Graylog though, since it required some annoying maintenance from them, and so at some point the decision was made to switch to Splunk instead. And when Splunk was finally rolled out, I had to find out that it was incredibly, ridiculously slow. Honestly, looking at it, I don't quite understand how they are even selling it. If you've used Splunk, you might know that it has two modes: “Smart” and “Fast”. In “Smart” mode, the same query for an hour of logs was tak…  ( 4 min )
    I've just released git-gpt-commit v0.9.0! 🎉
    I've just released git-gpt-commit v0.9.0 — a Git extension that uses OpenAI's GPT models to automatically generate commit messages via the git gpt commit command. The default model has been upgraded to OpenAI’s GPT-4o. blazing-fast response speed (about twice as fast as GPT-4.1), allowing it to generate commit messages in an instant. very cost-efficient, at half the price of GPT-4-turbo. Previously, only English was supported. Now, with: git gpt lang You can choose from 12 languages for your commit messages: Previously, there was no option to add prefixes to your commits. Now, with: git gpt prefix You can toggle the inclusion of commit prefixes like feat:, fix:, or refactor:. Previously, you had to write your API key in a .env file in your project directory. Now, with: git gpt open-api-key You can now safely add and manage your OpenAI API key directly from the CLI. .env method is still supported as well. git gpt config You can now view all your current settings at once. Once installed, start by registering your OpenAI API key using the command above. Then, just stage your changes with git add, and run: git gpt commit The tool will analyze the staged changes, send them to the GPT model, and generate a context-aware commit message. You’ll need an OpenAI API key. npm install -g @laststance/git-gpt-commit While IDEs like VSCode and Cursor offer AI-assisted commit message generation, I couldn’t find a CLI tool that does the same — and that’s where I spend most of my time working with Git. Most of the features I personally wanted are now implemented, so I’m pretty happy with this release. Links: GitHub|npm  ( 4 min )

    Finding the Row Containing a Target in a Sorted Matrix in Python
    In this problem, you're given a matrix of integers where each row and each column is sorted in ascending order. The goal is to find the index of the row that contains a specific target value. If the target value is not found in the matrix, return None. This is a common matrix problem that can be solved efficiently by taking advantage of the sorted structure. Instead of checking each cell (which would take O(n × m) time), you can reduce the complexity to O(n + m), where n is the number of rows and m is the number of columns. We make use of the matrix's properties—namely that values increase as we move right and down, and decrease as we move left and up. Start from the top-right corner of the matrix. Use a loop to traverse the matrix: If the current value equals the target, return the current row index. If the current value is greater than the target, move left. If the current value is less than the target, move down. If the loop completes without finding the target, return None. def find_row_with_target(matrix, target): if not matrix or not matrix[0]: return None # Matrix is empty n = len(matrix) # Number of rows m = len(matrix[0]) # Number of columns # Start at the top-right corner row, col = 0, m - 1 while row = 0: if matrix[row][col] == target: return row # Target found elif matrix[row][col] > target: col -= 1 # Move left else: row += 1 # Move down return None # Target not found matrix = [ [1, 2, 3, 4], [5, 6, 7, 8], [9, 10, 11, 12] ] print(find_row_with_target(matrix, 7)) # Output: 1 print(find_row_with_target(matrix, 13)) # Output: None This solution demonstrates how understanding data structure properties can lead to more efficient algorithms. Instead of brute-force search, a directional approach through the matrix takes full advantage of the sorted nature, resulting in a linear time complexity relative to the dimensions of the matrix.  ( 4 min )

    How to use EXPLAIN to fix slow queries in MySQL
    Slow queries can quietly erode performance, which frustrates users and strains your system. Fortunately, MySQL offers EXPLAIN, a diagnostic tool that reveals how your queries execute. Think of it as a window into your database engine’s decision-making process. With EXPLAIN, you can figure out exactly why a query is underperforming. Maybe it’s looking at too many rows, ignoring indexes, or struggling with joins. This understanding is key for developers and database administrators who are aiming to optimize performance. To use EXPLAIN, simply place it before your query. It works with SELECT, INSERT, UPDATE, or DELETE statements. For instance: EXPLAIN SELECT name, email FROM customers WHERE age > 30; This will return the query execution plan in table format. +----+-------------+-----------+…  ( 8 min )

    As someone who's been working as an Ab Initio developer, I’ve had a front-row seat to a reality that many in the data world seem to overlook: Most of the features that big data platforms like Hadoop or Spark introduced as “innovative” already existed — and were mature — in Ab Initio long before they became industry buzzwords. This post isn’t about fanboyism. It’s a perspective from someone who’s seen the nuts and bolts of how real enterprise-scale data processing works, and how underappreciated Ab Initio really is. Partitioning in Hadoop? Great. But Ab Initio had it long before the big data wave hit. The platform's Co>Operating System supports native massively parallel processing (MPP), with built-in strategies like: Round-robin partitioning Key-based partitioning Broadcast or replicated p…  ( 4 min )
    How to Fix Side Effects Between Jest Tests in TypeScript
    Introduction When working with Jest in a TypeScript environment, particularly with mocked functions, you may encounter issues where one test affects another. This problem often arises when mocking is not properly reset, leading to test interference. In this article, we’ll explore why this side effect occurs and provide you with effective solutions, especially in your example involving test cases for the loginPagePresenter. Understanding the Side Effect In your case, the issue stems from the way Jest mocks the apiGateway.post function. When one test modifies the mocked implementation but fails to reset it afterward, it can inadvertently influence subsequent tests. Jest mocks maintain their state across tests unless specified otherwise. This can lead to unexpected results, especially in scen…  ( 4 min )
    Modern CSS Spritesheets with Native HTML Elements
    The common approach to using sprite sheets involves applying CSS classes with pre-calculated coordinates to control the positioning within the sheet. This typically relies on background-image, which does not natively support features like alt text or lazy loading that come built-in with elements. Additionally, using can improve accessibility and semantics depending on how the image is used. This approach builds upon an article on css-tricks, and expands it by introducing scaling of the individual sprites. Skip to Codepen Demo object-fit: none and object-position: x y allow us to select specific areas of an image which is the basis of this idea. The object-position values need to be pre-calculated, just like in the class-based approach. This could be stored as an object literal…  ( 5 min )
    Prompt Engineering
    💡 Think about Inputs and Outputs.... If the Input is confused one, the Output will also be a confused one. So, to get a good Output from anything there must be a good Input. ➡️ What is the Prompt Engineering ? Simply, It is the skill of writing effective and clear instruction (effective and clear prompt) for AI tools like ChatGPT / Claude / Google Gemini.. to get the best Results 🡺 ex ): When we want to get a story using AI tool , prompt 1 -: " Give me a story " prompt 2 -: " Write a 10 sentence story about two best friends in a Consider these two prompts ; prompt 1 - - 👎 [ bad prompt ] prompt 2 - - 👍 [ good prompt (not bad) ] There are not even basic instruction in prompt 1. What is this story about ? What is the purpose of story ? How many sentences or words do you need for the story ? So we won't get a good output using this prompt (prompt 1). ➡️ How to write a clear and effective prompt for AI tools ? These are written under some Models. One of them is shown bellow ⭐ RACEC Model Role - Define the role or persona of the chatbot ex : Think like this.. / Act as that person... Action - Explain as you give instructions to an assistant ex : Write and essay, letter ,email / Analyze this sales data. Context - What is the Target Audience ex : write to university professor Examples - Using examples for your prompt Constraints and Formatting - Explain what are the necessary and 📁 By using models like RACEC, you can structure your prompts to be more effective, creative, and useful !!!  ( 3 min )
    Hoisted and Confused? Let’s Decode JavaScript’s Scope Magic
    JavaScript isn't broken — but if you've ever wondered why a variable returns undefined or a function throws an error before it's even called... you're not alone. Many developers hit weird bugs due to scope and hoisting without realizing what's really going on. I just dropped a post that breaks down: Why var, let, and const behave so differently How JavaScript really handles function and block scopes What hoisting actually does (and doesn’t) How to write bug-free, predictable code If you've ever thought “JavaScript makes no sense”, this post is for you. 👉 I wrote the full breakdown here: Understanding JavaScript Scope and Hoisting: A Beginner to Intermediate Guide  ( 3 min )
    Java Script Engine(How JS Works Behind The Scenes The Engine)
    ** **A JavaScript engine is the core software component that executes JavaScript code, typically as part of a web browser or runtime. Modern engines are highly optimized and use Just-In-Time (JIT) compilation to improve performance . For example, Google’s V8 engine (written in C++) drives Chrome and Node.js, while SpiderMonkey runs in Firefox, JavaScriptCore in Safari, Chakra in (legacy) Edge, and Hermes in React Native. Each engine implements the ECMAScript standard (the formal spec for JavaScript) and often also supports WebAssembly execution in the same sandbox . This means JavaScript engines are critical for making web pages responsive and fast, and even power serverside Node.js apps and desktop frameworks like Electron .

    Ditching Postman: Why and How I Transitioned to Bruno
    As a developer who regularly works with APIs, Postman has been the go-to choice for testing, documenting, and sharing across teams. However, over time, I began to feel the bloat. Postman became increasingly heavy, slow to start, and frustrating to use in version-controlled environments. That's when I discovered Bruno: a lightweight, open-source API client aiming to take on Postman's heavyweight legacy. In this article, I'll walk you through why I made the switch from Postman to Bruno, what the transition looked like, and how my workflow has improved. Needing no introductions, Postman is undoubtedly a powerful tool. But with power often comes weight: Resource Heavy: Postman's Electron-based architecture makes it noticeably slow and memory-hungry.

    In the Programming World, There Are SIMPs Too
    Let’s talk about something nobody puts on the shiny LinkedIn posts: there are SIMPs in tech too. And no, I’m not talking about romantic simping.

    How Manual QA Can Implement Left-Shift Testing in Frontend
    Introduction In traditional software development, testing often occurs late in the cycle, leading to bottlenecks and delayed releases. Left-shift testing is a proactive approach where testing activities are introduced earlier in the development lifecycle. While automation is often associated with left-shift testing, manual QA testers can also play a crucial role in implementing this strategy—especially in frontend development. This article explores how manual QA testers can adopt left-shift testing principles to improve frontend quality, reduce defects, and accelerate delivery. Left-shift testing means shifting testing activities left (earlier) in the software development lifecycle (SDLC). Instead of waiting for a fully developed feature, testers engage early in requirements, design,…  ( 5 min )

    How to Create Unique ASCII Art Boxes with Background Colors
    Introduction Creating visually appealing ASCII art boxes with distinct background colors can pose a unique challenge for web developers. Traditional methods often involve using multiple div elements to simulate intricate boxes, which can be cumbersome and inefficient. In this article, we'll explore a more effective way to design ASCII art boxes that not only enhances visual appeal but also offers you the flexibility to create varied shapes and sizes effortlessly. Why Traditional Methods Are Limiting Many developers resort to using two overlapping div tags to create the illusion of a colored background within an ASCII box. While this method can work, it often complicates the implementation. Adjusting the size of each box requires recalibrating both divs, which is not only tedious but can le…  ( 5 min )

    MySQL vs MongoDB for SaaS: Which Database Should You Choose in 2025
    For a SaaS (Software as a Service) product, choosing between MySQL and MongoDB depends heavily on the type of data, scalability needs, and how the app works. Use Case Recommendation Traditional SaaS (multi-tenant, structured data, relational) ✅ MySQL Flexible, unstructured, dynamic data (e.g., user-generated content, document-heavy) ✅ MongoDB Feature MySQL (Relational) MongoDB (NoSQL Document) Data Structure Tables, Rows, Foreign Keys (SQL) JSON-like Documents (BSON) Schema Fixed schema (strong structure) Schema-less (flexible) Joins & Relationships Native support Complex joins are harder Transactions Strong ACID support ACID (limited or requires special setup) Scalability Vertical + Read replicas Easily horizontally scalable Performance Great for complex queries, joins Fast for large, flexible datasets Multi-Tenancy Support Very strong (tenant per row, schema, DB) Requires thoughtful design MySQL: SaaS with complex relational data (users, roles, payments, subscriptions). Requires data integrity and transactions (e.g., financial systems). Example: B2B CRM, ERP, Invoicing software. Strong multi-tenant support using shared schema with tenant_id. MongoDB: SaaS with highly dynamic or nested data, like CMS or analytics dashboards. You don’t rely heavily on relationships or joins. You need to store flexible documents per user. Faster iterations and schema evolution. SaaS Type Best DB Project Management Tool (tasks, users, teams) ✅ MySQL CMS/Blog Platform ✅ MongoDB Analytics or IoT Dashboard ✅ MongoDB Accounting / Billing SaaS ✅ MySQL Chat/Messaging SaaS ✅ MongoDB (with Redis/Cache) Some large SaaS companies use both: MySQL for core user/accounts/transactions. MongoDB or ElasticSearch for logs, analytics, unstructured content. If you are: Building a structured SaaS with users, payments, plans, etc. → go with MySQL Building a dynamic content-based platform or analytics service → go with MongoDB  ( 3 min )

Many of our clients are tech enthusiasts and small companies that want to avoid the complexity of configuring and maintaining Keycloak. Our larger clients, on the other hand, demand resilience. However, resilience is often measured in terms of Monthly Active Users (MAUs), without fully considering the exposure of their service. For example, take two hypothetical compa…  ( 6 min )
    How to Fix JWT Signature Validation Errors in C#
    When working with JWT authentication in C#, you might encounter a common issue: the token signature validation fails due to a missing 'kid' (Key ID) in the header. This issue often surfaces when using the HS256 algorithm without a kid component, particularly when your token is validated against a set of keys that do not match. Understanding JWT Tokens and Signature Validation JWT (JSON Web Token) is a widely used token format for secure communication between parties. A JWT typically consists of three parts: header, payload, and signature. The header contains information about how the token is signed, including its algorithm and, optionally, a 'kid' if multiple signing keys are involved. In situations where the 'kid' is missing, the application may not be able to match the signing key prope…  ( 4 min )

    Why Managed Side Effects Are a Deliberate Design Decision in Elm
    Elm is renowned for its commitment to reliability and predictability in web applications. One of the key design decisions behind Elm’s success is its strict enforcement of managed side effects.

    The Rise and Fall of Comet ATLAS
    “An icy visitor flames out in dramatic fashion”– Sean Walker A comet is a small icy object that orbits the Sun. It’s made of dust, rock, and frozen gases (like water ice, carbon dioxide, and more). I’m sure that everyone’s familiar with this definition of a comet, but today we’re not talking about comets in general but a specific one — ATLAS! Comet ATLAS or C/2024 G3 was named after ATLAS- Asteroid Terrestrial-impact Last Alert System, which was the first to discover it. Comet ATLAS was a 19th-magnitude object. To explain, the magnitude of an object measures its brightness. The brighter the object the lower the number. The comet is also described as having a diffuse coma and a short tail.

    File Read & Write
    In Java, file reading and writing can be done efficiently using buffered streams, readers, and writers. Here's a short explanation with examples: 1. Buffered File Reading (Using BufferedReader) Buffers data for efficient reading (instead of byte-by-byte). import java.io.BufferedReader; import java.io.FileReader; import java.io.IOException; public class ReadFile { public static void main(String[] args) { try (BufferedReader reader = new BufferedReader(new FileReader("file.txt"))) { String line; while ((line = reader.readLine()) != null) { // Reads line-by-line System.out.println(line); } } catch (IOException e) { e.printStackTrace(); } } } 2. Buffered File Writing (Using BufferedWriter) Buffers data for efficient writing. import java.io.BufferedWriter; import java.io.FileWriter; import java.io.IOException; public class WriteFile { public static void main(String[] args) { try (BufferedWriter writer = new BufferedWriter(new FileWriter("output.txt"))) { writer.write("Hello, Java!"); writer.newLine(); // Adds a newline } catch (IOException e) { e.printStackTrace(); } } } 3. Key Classes Class Purpose FileReader / FileWriter Reads/Writes characters (text files). BufferedReader / BufferedWriter Wraps readers/writers for buffered I/O. FileInputStream / FileOutputStream Reads/Writes bytes (binary files). Scanner Alternative for reading text (e.g., new Scanner(new File("file.txt"))). 4. Try-with-Resources Automatically closes files (no need for finally blocks). Used in the examples above (try (BufferedReader ...)). When to Use? Use BufferedReader/BufferedWriter for text files. Use FileInputStream/FileOutputStream for binary files (images, etc.). Use Scanner for parsing structured text. Let me know if you'd like a deeper explanation! 🚀  ( 3 min )

    The Art of Deep Comparison in JavaScript (No Loops Required!)
    ✅ Understanding the Goal You're being asked to implement a function called deepEqual(valueA, valueB) that checks if two values (which can be primitives, objects, or arrays) are deeply equal. The keyword here is deep, this means we can’t just check equality on the surface (like ===), especially for things like objects and arrays. We need to go into nested levels and check if all elements or properties match recursively. 🧠 Think Like This, Before you jump into code, ask yourself questions like: -> What types of values can valueA and valueB be? -> How do I handle primitive types vs arrays vs objects? -> What does it mean for arrays or objects to be “equal”? -> Should I use recursion? 🤔Design Your Thinking Strategy: Base case: If a === b, return true. Type check: If types differ, return false. If both are arrays: Check length. Recursively compare each element. If both are objects (but not arrays): Compare keys. Recursively compare each corresponding value. Otherwise: return false. 🔁 Why Recursion? Why Loops Alone Aren’t Enough? A simple for loop works great when you're comparing flat structures, like two arrays of numbers. But when the data can go many levels deep , arrays inside objects inside arrays, etc. you’d need: a loop inside a loop inside a loop... 😵 or a smarter approach that can handle any depth That’s Where Recursion Shines. Recursion is perfect for tree-like or nested structures, because you can say: “If the current level is an array or object, go deeper and run the same logic again.” So your function ends up being clean and adaptable to any depth. ⚡️Implementation of the deepEqual function using recursion: With a clear understanding of recursion and careful handling of data types, you now have a robust deepEqual function that can accurately compare even the most nested structures, a must-have tool in any JavaScript developer's toolkit.  ( 3 min )
    Why Netflix Doesn’t Trust Auto-Increment IDs: The Untold Power of UUIDs in a Distributed World
    At first glance, an ID might seem like the most boring part of your application. It's just a unique identifier, right? But if you're building systems that scale - across regions, across teams, across microservices - your ID generation strategy can be the silent hero or the hidden landmine. And that’s exactly why companies like Netflix, Twitter, Stripe, and Shopify have ditched traditional auto-incrementing IDs in favor of UUIDs and Snowflake-like systems. Let’s explore why UUIDs are not just random gibberish, but a critical architectural decision in high-scale systems - and what lessons we can steal from the giants.

    When reading discussions about C++ variable definitions and their associated rules, it’s essential to understand the distinctions between variable definition, initialization, and assignment. Each concept plays a crucial role in how variables behave within C++ code, and knowing these differences can significantly enhance your programming efficiency. Let's delve deeper into variables in C++ and clarify these terms with examples. Understanding Variable Definition In C++, variable definition is the process of declaring a variable to let the compiler know the variable’s type and its name. For instance: int x; // Variable definition Here, int x; tells the compiler to reserve space in memory for an integer variable named x. However, at this point, x does not hold any value; it’s simply defined. …  ( 5 min )
    Google’s “Desktop View” Might Just Kill Samsung DeX
    Google is testing a new “Desktop View” mode in Android — and it’s more than just screen mirroring. We’re talking about taskbars, resizable windows, mouse support, and full-on multitasking. Basically, a PC layout powered by your phone. If this rolls out, it could mean you won’t need a Samsung device to get that DeX-style desktop experience. Hidden taskbar (like Windows or ChromeOS) Drag-and-drop between apps Resizable, windowed apps Smooth support for external monitors Mouse + keyboard ready It’s currently tucked away in Android beta builds, but signs suggest Google is moving fast with this. Samsung DeX gave us a glimpse of mobile desktop computing. But now Google is building something native — possibly for all Android phones. That means more freedom for users, especially those who want to work on the go with just a phone and a screen. This could shift how we think about smartphones in workspaces.

    What is Machine Learning? A Beginner’s Journey Through the World of Smart Algorithms
    Imagine you're trying to teach a child how to recognize fruits. You show them dozens of apples, bananas, and oranges, telling them the name of each fruit. Over time, the child learns to distinguish between them, even when they see new fruits for the first time. This, in a way, is what Machine Learning (ML) is all about—teaching machines to learn from data and make decisions or predictions without being explicitly programmed. 🧠 So, What Is Machine Learning? At its core, Machine Learning is the art and science of solving problems by learning from data. We start with a problem, gather data related to it, and then use algorithms to build a statistical model that can make sense of new, unseen data. But ML isn’t one-size-fits-all. There are several ways to teach a machine, depending on what k…  ( 4 min )

    Analyzing the Backward Insertion Sort: An Insightful Tool by Fernando Pelliccioni
    In the vast world of computer science, while the foundations and principles of algorithms remain consistent, the ways we approach, implement, and analyze them continue to evolve. Today, we’ll delve into a distinct implementation of the insertion sort algorithm and an innovative tool that simplifies its analysis, both brought to the fore by Fernando Pelliccioni. The provided algorithm, while rooted in the classic insertion sort paradigm, offers a twist — working its magic backward: `function insertion_sort_backward(f, l, r) { } function linear_insert_backward(c, l, r) { var s = sequence(array_descending(), "s", lt); print(s); Understanding an algorithm is one thing; seeing it in action is another. Fernando Pelliccioni introduces an insightful GUI tool for this very purpose: componentsprogramming.com/algorithms. This interactive platform not only animates the algorithm’s execution but also serves insights into memory sequences, variables, stack calls, and various operation statistics. A glimpse into the potential data output: n: 10 (Note: The above metrics are illustrative and may not reflect the actual values for specific runs.) While the foundational algorithms might be familiar territory, it’s the nuanced implementations and tools for deeper understanding that elevate our coding journeys. Fernando Pelliccioni’s distinct implementation of the insertion sort and the accompanying analysis tool stand as testaments to innovation in the world of algorithms.

    O cérebro odeia pensar: o poder da interface óbvia
    Dia 2 - Neurointerfaces — Como nosso cérebro enxerga o Frontend “Don't make me think.” — Steve Krug Essa frase virou um clássico do design de interfaces. E ela tem base neurocientífica: nosso cérebro evita ao máximo o esforço cognitivo desnecessário. Segundo a Teoria do Processamento Dual (Kahneman, 2011), o cérebro humano opera com dois sistemas: Sistema 1: rápido, automático, intuitivo. Sistema 2: lento, deliberado, requer esforço. Sempre que possível, o cérebro usa o Sistema 1 — e só ativa o 2 se for realmente necessário. Isso significa que interfaces que exigem leitura, análise ou adivinhação ativam o sistema mais lento — e geram frustração. Ícones sem legenda (usuário precisa adivinhar) Menus escondidos (hambúrguer, submenus profundos) Mudanças de padrão (ex: botão de "enviar" que parece um ícone) Elementos previsíveis e familiares Legendas claras Hierarquia visual forte Espaço em branco bem utilizado Estudos de eye-tracking (rastreio ocular) mostram que usuários criam um padrão de leitura em F na tela. Isso significa que eles escaneiam de cima para baixo e da esquerda para a direita — e ignoram o resto. Kahneman, D. (2011). Thinking, Fast and Slow. Krug, S. (2014). Don't Make Me Think, Revisited: A Common Sense Approach to Web Usability. Nielsen Norman Group (2006). F-Shaped Pattern For Reading Web Content. Essas obras explicam por que o design intuitivo funciona melhor: ele não força o cérebro a sair do “modo automático”. Reduza a necessidade de pensar. Use padrões comuns da web. Priorize clareza sobre criatividade. Não reinvente botões sem motivo. Dê pistas visuais. Ícones com texto, hierarquia, espaçamento. Teste com usuários reais. Se alguém hesita antes de clicar, sua interface não está clara o suficiente. Criar uma interface clara é um ato de empatia: você está poupando energia mental do seu usuário. Se ele entender o que fazer sem precisar pensar, você venceu. Qual interface você achou mais confusa recentemente? Comenta aqui e vamos analisar no próximo post da série! 👇  ( 4 min )

    AI-integrated design systems and component libraries
    What if your design system didn't need to ship components in a component library? From an engineering standpoint, most of a design system's maintenance overhead is creating and shipping components for a specific framework coupled to a styling system of some kind. I've been asking the same thing on Medium. And then built a POC to see if it would work and made it available in Github. If using AI agents, component libraries break free of framework and style constraints by generating components at build time from prompts and generator functions. They're still driven by design through tokens and themes, but without prebuilt components. It gets even better when using RAG for distribution and documentation, eliminating tools like Storybook in favor of on-demand generation by AI agents using the system itself, not a collection of stories or API documentation.  ( 3 min )

    Franchise Agreement: A Complete Guide for Business Owners
    Expanding your business through franchising can be a lucrative strategy, but it requires a solid legal foundation. At the heart of this foundation lies the Franchise Agreement—a legally binding contract that defines the relationship between the franchisor (the brand owner) and the franchisee (the investor or business partner).

    Git Native API Client (free, no login)
    Hey all, We recently started working on an API Client - Voiden - and wanted to share it here to get your thoughts and feedback. Over the past few years, we found ourselves managing way too many tools just to work with APIs: one for api specs, another for docs, a third for tests, etc etc. Eventually it starts to feel more like a performance than actual work. So we built Voiden: A git-native, extensible, and lightweight client that brings everything—specs, docs, tests, mocks—into one place. No bloat, no lock-in, no "platform overhead." Just structured API workflows that don’t fight your tools or your team. A few things we care about: -Reusability and composability : APIs as building blocks, not silos. -Structure over scatter : everything lives together in one workspace. -No sign-in required : you can use it without creating an account. Free and open — we are building this with the community in mind. Just to be clear: The goal is NOT to replace OpenAPI, but to provide a layer around existing specs that feels coherent, hackable, and friendly to real-world dev workflows. You can check it out here: https://voiden.md/ And if you have feedback, suggestions, or just want to follow along: https://github.com/VoidenHQ/feedback We are still early, but would love to hear what you think—what you like, what is missing. Appreciate any time you take to try it out. Nikolas  ( 3 min )

    How to Store Polymorphic Objects in C++ STL Containers?
    Introduction Can we store polymorphic objects by value in C++ STL containers? This topic often arises among C++ developers, particularly with the challenges posed by object slicing when dealing with base and derived classes. The crux of the issue lies in the behavior of STL containers and how they handle objects. In C++, when we store derived class instances in a container that holds base class objects by value, object slicing occurs, which results in the loss of the derived class-specific behaviour. This article aims to explore this concept specifically within the context of C++11 and later revisions, dissecting the challenges and potential approaches. Understanding the Slicing Problem When you store a derived class object in a container designed to hold objects of its base class by value…  ( 5 min )

    Securing Temporary Credentials in AWS: What You Should Be Doing But Probably Aren’t
    🔐 Temporary credentials in AWS are powerful—but also widely misunderstood. They allow developers and systems to access AWS resources without relying on long-lived access keys. But just because they expire doesn’t mean they’re safe by default. In this post, I break down: ✅ When and why to use temporary credentials 🧱 Where things go wrong (over-permissive roles, lazy session durations…) 🔒 Best practices for keeping temp creds secure 🧠 Advanced use cases like federation and IAM Roles Anywhere I’ve seen real-world setups where: Temp credentials lasted 12 hours Were used with AdministratorAccess In CI/CD pipelines with no monitoring That defeats the whole point of ephemeral access. Should Be Doing 🔸 Use least privilege roles Scope your roles tightly and use IAM condition keys like aws:SourceIp. 🔸 Shorten session durations 15–30 minutes is more than enough for most automation tasks. 🔸 Log STS usage with CloudTrail Every AssumeRole or GetSessionToken should be traceable and alertable. 🔸 Require MFA where appropriate Especially for sensitive role assumptions—break-glass or prod access. 🔸 Automate responsibly Don’t reuse temporary creds or store them insecurely in config files. Use the SDKs properly. For non-AWS workloads (like on-prem apps), IAM Roles Anywhere lets you issue short-lived AWS credentials using signed certificates. It's a powerful addition for hybrid setups, but comes with its own set of guardrails. The original article goes deeper into: Federation setups with Okta or AzureAD Example real-world misuses (and fixes) Credential rotation strategies 👉 Read the full guide here Let me know: How is your team managing AWS access today?

    Why does Swift have issues with opaque types for variables?
    When diving into the Swift language, especially for those new to the community, understanding how the Swift compiler treats opaque type declarations can be confusing. In your example, you're encountering a common scenario that many developers face when dealing with opaque types in Swift. Let's clarify this by breaking down your code and explaining why the behavior you're seeing is occurring. Understanding Opaque Types in Swift Swift's opaque types, introduced with the some keyword, allow developers to specify that a function will return a value conforming to a specific protocol without revealing its exact type. This is particularly useful for abstracting away implementation details while still adhering to protocols. In your code: protocol Animal {} class Dog: Animal {} func getMeADog() -…  ( 5 min )
    What is FTP? File Transfer Protocol
    At its core, FTP is a standard network protocol used to transfer files between a client and a remote server. Introduced in the early days of the internet, it was originally designed to simplify data sharing across ARPANET. Today, its primary use remains the same—allowing users to upload, download, and manage files between devices and systems across networks. While web browsers offer limited FTP support, professionals often turn to dedicated tools like FileZilla and Cyberduck to handle more advanced workflows. An FTP session typically initiates two connections: Control Channel: Handles command exchange and session setup. Data Channel: Transfers the actual file content. This dual-channel approach allows FTP to streamline complex file operations, enabling simultaneous uploads and downloads wi…  ( 4 min )

    Common SQL Mistakes and How to Avoid Them
    Structured Query Language (SQL) is an essential tool for working with databases, but even seasoned developers sometimes make mistakes that can lead to slow queries, inaccurate data, and inefficient systems. When summarizing data, the GROUP BY clause organizes information into meaningful groups. However, misusing GROUP BY can lead to incorrect results—sometimes without obvious errors. A database tracks employee salaries per department. Someone writes: sql To summarize salaries by department, the query should be: sql sql Only group necessary columns—non-grouped columns need aggregate functions. Use HAVING instead of WHERE for filtering grouped results: sql During testing, SELECT * is quick and handy. But in production? It slows queries, overloads networks, and makes applications harder to maintain. sql sql Explicitly specify needed columns instead of SELECT *. Use LIMIT for large queries: sql sql sql Indexes speed up data retrieval, but poorly designed indexes can slow down updates, inserts, and deletes. sql A better strategy: sql Index columns frequently used in WHERE clauses. Avoid over-indexing, which slows write operations. Use EXPLAIN or ANALYZE to check query performance: sql Use composite indexes only when queries filter by multiple columns: sql NULL values represent missing information, and if not handled correctly, they can cause errors or misleading results. This query calculates average salaries: sql Ensure NULLs are accounted for: sql sql Use IS NULL and IS NOT NULL to prevent logic errors. Replace NULLs using COALESCE() or IFNULL(): sql Validate NULL handling in reports to avoid misleading calculations. SQL mistakes can affect speed, accuracy, and system stability. But with the right practices, you can write efficient, optimized queries that scale well. GROUP BY must include all non-aggregated columns to avoid incorrect grouping. Never use SELECT * in production—fetch only required data. Index smartly, targeting commonly searched fields. Handle NULLs carefully, ensuring accurate calculations.  ( 4 min )

    Exploring CLI Alternatives to Claude Code for Agentic Coding Workflows
    If you're building coding agents or automated developer workflows, you'll quickly discover the challenge of finding a robust, non-interactive CLI tool for code generation and modification. While human-in-the-loop coding (where a developer guides the AI) is still the gold standard for complex software, there's a growing need for tools that can operate fully autonomously—especially for simple, repetitive tasks or as part of larger agentic systems. I'm working on building an AI agent for creating playable ads—essentially mini games that can be used as interactive advertisements. This involves integrating various assets, ensuring the output works in both portrait and landscape modes, and adhering to the ad format requirements of different ad networks.

    How to Retrieve a JSON Object and Access Token in PHP
    Introduction If you're working with APIs in PHP, you might often need to retrieve JSON data from a URL. In this article, we will demonstrate how to fetch a JSON object from a given URL and extract the access_token value from it. Understanding how to interact with JSON responses is crucial for seamless API integrations. Why This Issue Occurs Often, APIs return data formatted as JSON.

    🐧 Why I switched to Linux (and don’t regret it a second)
    When I first thought about switching from Windows to Linux, the main reason was simple — I want to control my computer. ⚙️ I love to automate everything One of the main reasons I chose Linux is the ability to automate everything. Every update, every new package — I decide what and how to install. This isn’t tied to forced downloads like in Windows. This is my freedom. 🌍 A world of options Linux gives you a huge variety of distributions, each suited to different needs. It’s like a builder where you choose what you need: I started with Ubuntu, because it’s stable, user-friendly, and has good documentation. But now I’m getting more interested in Arch and Fedora. I’ve realized that in Linux, it’s easy to switch between distributions, migrate between them, and adapt the system to your needs. 💻 Tech and CTF My passion for CTF and cybersecurity gave me even more reasons to switch to Linux. This system provides me with the tools to work with security, set up virtual machines, create test environments, and perform various attacks. You can’t achieve that in Windows, not to the same extent. Linux is a system for people who not only want to use technology but also understand it from the inside. For me, it’s not just an operating system, it’s a tool for growth and self-expression. 🌟 My freedom After switching to Linux, I felt that I was finally in control of my system. It’s not just an OS, it’s an environment that allows me to build, optimize, and use my computer the way I need. 🚀 Final thoughts If you’re tired of your computer not being yours, try Linux. A system where you decide how everything works. Where you can customize everything, automate it, and learn. It doesn’t matter if you’re a beginner or an experienced user — Linux has something for everyone.

    Bypass WhatsApp Template Limits with a Button-Triggered Formatting Flow
    Summary WhatsApp imposes a 24-hour customer-service window during which you can send any message; outside of it, only template messages (unformatted) are allowed. Goalmatic.io needs to let users send richly formatted content (articles, poems, etc.), so we built a two-step workaround: Template Send: Strip formatting and send via a WhatsApp template. On-Click Upgrade: Include a “Get Formatted Text” button in the template. When the user clicks, the 24-hour window reopens, allowing us to send the original, fully formatted message. Below is an end-to-end example in Node.js using the WhatsApp Cloud API. WhatsApp’s customer-service window rules mean: Within 24 hours of a user message, you can send any content (text, media, formatted). After 24 hours, only template messages (unformatted, pre-app…  ( 5 min )
    How to Handle Errors in SwiftUI View Model Effectively?

In this article, we will explore common pitfalls in error handling when dealing with a view model in SwiftUI. We will focus specifically on how to ensure that errors thrown from your view model can be gracefully handled at the view level. Understanding the Issue In Swift applications, especially those using SwiftUI, it can sometimes occur that errors that are thrown from a view model do not propagate to the view layer. This can lead to confusion as you may not see the expected error messages in your user interface. In your case, while the error logging from the network layer indicates that an error is being produced, the error isn't…  ( 5 min )
    A Developer’s Guide to Browser Storage: Local Storage, Session Storage, and Cookies
    When developing web applications, storing data in the browser is essential for maintaining user sessions, saving preferences, and improving performance. Three common methods for client-side storage are Local Storage, Session Storage, and Cookies. While they serve similar purposes, they differ in data persistence, size limits, and accessibility.

    Back After a Break — Building Something Meaningful!
    Hey Devs! 👋 Yeah, I know… it’s been a while 😅 LearningTrackApp (name still under construction 😅) So this new app I’m building is a platform made for NGOs — specifically the ones that teach underprivileged kids. The idea is to help them keep track of their students’ progress, batch sessions, timings, names — basically everything important in one place. It’s simple, but I think it’s gonna be really useful. The app has a few different roles to keep everything organized: Super Admin – can access and manage all the NGOs. Admin – manages just their own NGO. Supervisor – the on-site person ensuring sessions are running smoothly. Volunteers – the awesome people who teach the kids. Students – well, this one explains itself 😄 That’s pretty much what I wanted to share for now. I genuinely feel like this app can be something impactful, and I’m excited to build it step by step. I’ll be posting more about the tech, my role, and the challenges I face in the next few posts. Until then, peace out ✌️  ( 3 min )

Using Comments in SQL Two Main Types: Single-line -- Pull users created in the last week SELECT * FROM users WHERE created_at >= CURRENT_DATE - INTERVAL '7 days'; Multi-line /* Use this version for reporting Includes only verified accounts */ SELECT * FROM accounts WHERE verified = TRUE; Why and When to Comment Helpful When: Writing complex logic Sharing scripts with a team Disabling old queries during testing Avoid: Leaving sensitive info Explaining simple queries Letting comments go stale Different Engines, Different Capabilities MySQL: Supports versioned comments /*! */. PostgreSQL: COMMENT ON lets you label schema elements. SQLite: Keeps it basic and portable. SQL Server & Oracle: Great for documenting stored code and schema. FAQ How do I add comments in SQL? Use -- for quick notes or /* */ for multiple lines or blocks. Yes—wrap code in /* */ and it won’t run. Yes, both styles are widely supported with small engine-specific features. Only if they include secrets or mislead developers. Keep them clean and relevant. Conclusion SQL comments don’t take much effort but make a big difference.

    DevOps in Embedded Software? Let’s Be Honest: It Doesn’t Really Exist
    When people talk about DevOps, they usually mean something very specific: development teams continuously building and shipping code, and operations teams running and scaling that code in production—usually in the cloud. CI/CD pipelines automatically build, test, and deploy code through staging, QA, and production environments. The boundaries and responsibilities are clear. But what happens when you try to apply this same DevOps concept to embedded software development? Spoiler: it doesn’t fit. At least not in the way most people mean when they say “DevOps.” In embedded systems, developers write software that runs on physical devices.

    How to Document Constants in Python Effectively?
    In Python programming, it's common to define constants that are used throughout your code. These constants, stored in a file like constants.py, can help keep your code organized and make it easier to update settings or values in the future. However, when documenting functions that use these constants, developers often face the dilemma of whether to refer to the constants directly in the documentation or use their values instead. Why Use Constants in Python? Constants like PATH_DATASETS = "data/datasets/" and WIDTH = 416 serve as fixed values that can be reused across multiple functions in your program. This practice enhances code readability, maintainability, and minimizes the risk of introducing errors when changes are needed.

Since it was heavily prototyped on Windows, its functionality on other platforms (like macOS or Linux distributions) hasn't been extensively tested and might have some quirks. The core problem DevBridge aims to solve is reducing the friction developers face when context-switching between multiple projects, trying to understand unfamiliar code, or reusing existing solutions. It tries to make your terminal a bit smarter by integrating with Amazon Q. Here's a …  ( 4 min )

    Micro-Apps: The New Frontier of Scalable Mobile App Development
    What if I told you that building large, feature-packed mobile apps is no longer the smartest move? We're entering an era where micro-apps — small, self-contained, purpose-driven applications — are transforming how we build and scale mobile experiences. And if you're not exploring them yet, you're already behind. A micro-app is a lightweight, independent application designed to handle a specific task or feature. Think of it as a “microservice,” but for the frontend of mobile apps. They're typically: Built independently from the main app Focused on one specific use-case (e.g., payment, chat, onboarding) Easily deployable without affecting the entire app Written in a variety of frameworks or stacks Instead of one monolithic app that tries to do everything, you create multiple micro-…  ( 5 min )
    An Introduction
    👋 Hello Dev Community — From Guyana with Love! Hey everyone! I'm Nathaniel, a developer and computer science student from Guyana — a small country on the South American mainland. I’m passionate about writing clean code, building full-stack applications, and diving deep into topics like JWTs, web architecture, and system-level programming in C. But beyond that, I’m also deeply interested in how technology is growing (or struggling) in Guyana — from internet access to education to the startup scene. To share dev articles and tutorials, especially things I’ve learned or struggled with as a student and builder. To spotlight Guyana’s tech space, which I think deserves more global attention and internal discussion. To connect with other developers, both in the Caribbean and internationally, and learn from their stories as well. I’ve noticed there's not a lot of content on Dev.to about tech in Guyana, so I want to help change that. Whether you’re here for tutorials, dev opinions, or insights into building a tech career from a small country, I hope my posts can add value. Feel free to reach out, share your thoughts, or even suggest topics you'd like to see discussed.  ( 3 min )
    How to Implement a Generic get_keys Function in TypeScript?
    In TypeScript, creating generic functions can significantly increase your code's reusability and type safety. One common requirement is to extract keys from a given type, ensuring that your functions handle different types effectively. In this article, we will focus on how to implement the get_keys() function, which retrieves the keys of a specified type T. Understanding the Requirement The get_keys() function is designed to return the keys of any given type T. This function will be helpful when you want to dynamically work with the properties of objects or interfaces defined in TypeScript, especially when you are dealing with complex data structures. By doing so, you can create a more dynamic and type-safe codebase. Why Use TypeScript's Generics? Generics in TypeScript allow you to …  ( 5 min )
    Being In A Self-Managed Team Made Me Try The Most Expensive Hamburgers I've Eaten
    I originally posted this post on my blog. I didn't pay for the most expensive hamburgers I've eaten. An ex-employer did. When I say "most expensive," I mean the same greasy $5 or $10-dollar hamburger from a food truck or a corner in a busy street. But they felt expensive because I ate them while working overnight. In a past job, when my team was lagging behind the self-imposed deadlines of sprints, higher-ups told us: "This sprint is behind schedule. What are you going to do? You're a self-managed team, so decide that by yourselves. But if I were you, I'd choose to work overtime to keep up." "You're a self-managed team" was their subtle way of telling us to work extra hours, without accepting any responsibility. We didn't have any say in what tasks to do and how. We were only a self-managed team when it came to choosing to work overtime. They didn't pay us for that extra time. They only bought us hamburgers. And, when someone raised their concerns about the quality of those hamburgers, they told us we should be grateful because other companies buy their employees nothing to eat. If you're told you're part of a self-managed team, read the fine print. Look for signs of real self-managed teams: Look at job descriptions. Connect with people already working there. Ask follow-up questions during interviews. Otherwise, they might expect you to work overtime without compensation or just buy you an hamburger.

    Why TypeScript Enums Increase Angular Bundle Size and How to Fix It
    When optimizing Angular applications for performance, developers often overlook a silent culprit: TypeScript enums. While enums improve code readability and type safety, they introduce unexpected overhead in your final JavaScript bundle. This can lead to larger file sizes, slower load times, and diminished performance, especially on mobile or low-bandwidth connections. In this article, we'll explore how enums contribute to bundle bloat, why Angular's build tools struggle to optimize them, and which alternatives you can use to write cleaner, faster, and more efficient code. An enum is a TypeScript feature that lets you define a set of named constants. For example: export enum UserRole { Admin, Editor, Viewer } Under the hood, this compiles to something like: "use strict"; var UserRo…  ( 5 min )

    Destroy service for rxjs observables
    🧩 Implementation: @Injectable() export class DestroyService extends Subject { ngOnDestroy() { this.next(); this.complete(); } } 🧩 Question: ngOnDestroy() in this pattern? Even though DestroyService is a service and extends Subject, how does Angular still invoke ngOnDestroy()? 💡 Answer: Even though DestroyService extends Subject (which is not a component or directive), Angular still calls its ngOnDestroy() method if the service is provided at the component level. 🔑 Why ngOnDestroy() Gets Called in a Service ✅ Angular will call ngOnDestroy() if: The class implements OnDestroy AND it is a provider on a component or directive Example: @Component({ Then Angular treats the service like a directive-level provider, and because it has ngOnDestroy(): 🧠 Why It Works Even Though It Extends Subject Subject has no ngOnDestroy(). That's fine. You're extending Subject and adding ngOnDestroy() yourself. Angular doesn’t care that it extends Subject — it just sees: “This class was provided in the component” “It has ngOnDestroy()” ✅ Call it when the component is destroyed 🔁 Summary DestroyService is a service, but it's scoped to the component using providers: [DestroyService] It has a custom ngOnDestroy() method Angular calls ngOnDestroy() on component-scoped providers So you get an automatic, injectable "destroy notifier" for use with takeUntil() This is a neat Angular trick that combines: Lifecycle hooks Dependency injection RxJS into a reusable, composable unsubscribe mechanism.

    🌐📘 Understanding the CSS Box Model with a Simple Example 😊💻
    The CSS Box Model is one of the most important concepts in web design 🧱. It describes how elements are structured on a webpage — every HTML element is treated like a box with layers: content, padding, border, and margin. 💡 What I Made I created a simple webpage using HTML and CSS ✨. It shows a box with the message "Hello Kts". You can view the live demo here: The design is simple but effective — a colored box with space inside and outside, and a border to highlight the shape. 🧠 How the Box Model Works in My Project: Margin: It adds space outside the box (like a buffer from the edges) ➡️ Padding: It adds space inside the box around the text, making it look neat 🧍‍♂️ Border: This creates a clear outline around the box ⚫ Background color: I used a brown background to make the box stand out 🟤 🚀 Why It Matters? Understanding the box model helps you: Control spacing and alignment 🧩 Avoid layout issues or overlapping elements 🚫 Make your design clean and professional ✨ This project helped me understand the basics of styling elements in CSS. It’s a small step, but a strong foundation for building beautiful websites! 🛠️🌟  ( 3 min )

    Amazon Q Quack The Code: Pompeii Time Out
    This is a submission for the Amazon Q Developer "Quack The Code" Challenge: That's Entertainment! I built a text adventure game inspired by the history of ancient Pompeii. I believe my text adventure game differentiates itself by adding new features to the UI as you progress through the game. The first feature is a whole new text console that enables you to control and connect the two player characters between time. And the second is a map on the UI enabling you to better understand you position in the game. https://aproulx232.github.io/pompeii-time-out/ https://github.com/aproulx232/pompeii-time-out I used Amazon Q as a visual studio code extension.

The responses and code edits seem to be on par with Cursor. However, multiple times the chat context got stuck and would try over and over to write to my files with no success and no errors to work with.  ( 3 min )
    Is AI the New Oil? We Need to Talk About What It’s Costing Us
    We talk a lot about how smart AI is getting. Not in some sci-fi dystopia. In a real, physical, “it’s-happening-now” kind of way. Every time we ask a model to summarize a doc or spit out a joke, there’s a real-world cost i.e. electricity, water, hardware, minerals. And it adds up. Fast. 🔋 Power Hungry: How Much Juice Does AI Really Need? Let’s start with the basics. Training GPT-3 used up more than 1,200 megawatt-hours of electricity. That could’ve powered over a hundred homes in the U.S. for a full year. Now take GPT-4. That one? Easily 50x more, depending on the estimate. We’re talking small-city-level energy. And guess what?

    Why Does Go Allow Comparing Integer with String?
    In this article, we will explore why Go allows type comparisons that might initially seem surprising, particularly in instances like comparing an integer to a string. We'll explain the underlying mechanisms of Go's type system and how the language handles such comparisons without raising errors or panics. Understanding Go's Type System Go is a statically typed language, which means that the types of all variables are known at compile time. When you define a variable, its type must be explicitly declared or inferred, leading to a robust type safety framework. However, Go introduces a unique feature with the any type, which can hold a value of any type. This flexibility plays a crucial role in our example. The Role of the any Type In your provided code, we see the variable hello is declared …  ( 5 min )

    Avoid Getting Blocked! Implementing Amazon Price Monitoring with Python and Proxy IPs
    In the competitive world of e-commerce, monitoring prices on platforms like Amazon is crucial for businesses and savvy shoppers alike. However, scraping data directly from such websites can lead to IP bans and access restrictions. To mitigate these risks, using Python in conjunction with proxy IPs offers a safe and effective solution for price monitoring. Why Use Proxies for Amazon Price Monitoring? Anonymity: Proxies mask your real IP address, making it difficult for websites to track your scraping activities. import requests proxy = { http://your_proxy_ip:port", http://your_proxy_ip:port" def get_price(url): # Find the price element (this may vary based on the product page) url = 'https://www.amazon.com/dp/your_product_id' Static and Residential IPs: These are less likely to be flagged by Amazon.

    Uniapp开发鸿蒙应用教程之自定义导航栏
    连续分享了几天的Uniapp跨平台开发鸿蒙应用教程的文章,相信大家对跨平台开发已经有了初步的了解,今天分享一下跨平台开发中的自定义导航栏。 在Hbuilder的初始化项目中是自带了导航栏的,这是一个全局的导航栏,它的样式设置和修改是在全局的配置文件pages.json中进行。 现在打开pages.json文件,在globalStyle中有一些关于导航栏的属性,我们尝试修改一下: { "pages": [ //pages数组中第一项表示应用启动页,参考:https://uniapp.dcloud.io/collocation/pages ], "globalStyle": { 然后看到导航栏已经发生了改变: 这样的修改很方便很便捷,但是好像只有颜色和文字这些基础的属性可以修改,很多时候我们需要在导航栏上添加一些组件,比如按钮或者搜索框。 对于这种情况,uniapp也提供了相应的设置方案,还是在pages.json文件中,当我们需要为某一个页面的导航栏添加组件,就在对应的path路径下设置style,style中有个titleNView属性就是为导航栏添加自定义组件,像这样: "path": "pages/index/index", 但是幽蓝君亲测这种设置方式在浏览器运行时可以正常显示,在鸿蒙中是无效的: 所以在鸿蒙开发中我们需要自己定义导航栏。 再次回到pages.json文件,这次将navigationStyle设置成custom,作用是取消原生的导航栏: "path": "pages/index/index", 然后打开需要自定义导航栏的页面,我这里就直接在首页index.vue中操作,实现逻辑比较简单,就是在页面顶部添加一个导航栏大小的组件,然后在其中添加搜索框,相关代码如下: style="width: calc(100% - 40px);background-color: white;height: 35px;padding: 0px 10px;border-radius: 18px;" .custom-nav-bar { / background-color: #f8f8f8; 导航栏背景色 / 其他样式属性 */ 看一下运行效果: 今天就以添加一个搜索框为例,大家如果需要自定义其他的样式也是类似的实现方式。 以上就是uniapp跨平台开发鸿蒙应用中的自定义导航栏,感谢大家的阅读。  ( 3 min )

    The 1% of Hacking Nobody Talks About… But Should
    Most people think hacking is just about tools, code, or some flashy terminal with green text flying by. But that’s not what makes a real hacker. Let me tell you what really matters—the part only 1% truly understand… Forget the tools for a second. Real hacking starts when you ask the questions nobody else is asking: "Why does this work like that?" "What happens if I try something they didn’t expect?" "What’s behind this system they don’t want me to see?" It’s about curiosity. Obsession. Even rebellion. Not following tutorials step-by-step, but breaking patterns and learning how systems truly work under the surface. I’m teaching myself Python and networking— Not because I want to show off, but because I want to understand how the internet and machines actually think. I’m not here to be just another script kiddie. I’m building a foundation. Quietly. Daily. I don’t want fame. I don’t want likes. I want leverage. I want to be the kind of person who sees through the system—and knows how to bend it. A silent weapon. Sharp, skilled, and always learning. Are you learning just to pass exams? Or are you learning to break limits? Be real with yourself. The world’s already full of followers. We need more builders, breakers, and thinkers.

    How to Improve the Design of Your Cladogram in HTML?
    Creating a visually appealing cladogram can be quite challenging, especially if you're new to coding. It sounds like you want to improve the design aspects of your cladogram, which you initially created on Wikipedia and transferred to Neocities. The good news is that altering the style of your cladogram is achievable with some CSS adjustments. Understanding Cladogram Design Challenges Cladograms often display evolutionary relationships in a tree-like structure, which can look cluttered, particularly when the lines are too short or when the elements aren't properly spaced. Since you mentioned that you initially tried changing the padding but weren't satisfied with the result, let's delve into additional CSS properties that can help enhance the aesthetics of your cladogram.

    Uso da programação assíncrona em Python visando um sistema responsivo e performático
    Introdução Com a expansão dos serviços on-line, surge uma demanda cada vez maior por sistemas responsivos, performáticos e de alta capacidade de escalabilidade. O uso da programação assíncrona se mostra muito eficaz na obtenção destes atributos de qualidade durante o desenvolvimento de um software. Este artigo busca mostrar os benefícios e os contrapontos do uso da programação assíncrona em Python em sistemas "I/O-bound" (altamente dependentes de input e output) e outras tarefas que necessitam de execução paralela. Conceitos de programação assíncrona Computadores executam softwares de forma sequencial, isto é, uma instrução após a outra. Um software geralmente realiza múltiplas tarefas, e nem sempre faz sentido esperar que uma tarefa termine antes de iniciar a próxima (SKVORTSOV, 2021). Se…  ( 5 min )
    ARQUITETURA REST: PRINCÍPIOS, PADRÕES E APLICABILIDADE NO DESENVOLVIMENTO DE SISTEMAS DISTRIBUÍDOS
    RESUMO Palavras-chave: Arquitetura REST. Sistemas distribuídos. API. HTTP. Serviços Web. 1 INTRODUÇÃO 2 DESENVOLVIMENTO De acordo com Stein Junior (2021), REST surgiu da necessidade de criar interfaces simples e eficientes para a comunicação entre sistemas, principalmente via web. O autor afirma que "o objetivo era criar interfaces simples, escaláveis e independentes, facilitando a comunicação entre sistemas distribuídos por meio do protocolo HTTP" (STEIN JUNIOR, 2021, p. 10). A arquitetura REST é baseada na manipulação de recursos — objetos ou entidades de informação — que são identificados por meio de URIs (Uniform Resource Identifiers) e manipulados utilizando métodos HTTP padronizados, como GET, POST, PUT e DELETE. Fielding (2000) ressalta que uma das principais características do REST…  ( 6 min )
    How to Efficiently Use JAX for Numerical Pipelines
    Introduction In the world of numerical computing, transitioning from NumPy to JAX can offer significant performance benefits thanks to JAX's Just-In-Time (JIT) compilation and optimizations for GPU acceleration. However, this transition isn't always smooth for all operations, particularly for those that are heavily transformation-based, such as broadcast_to and moveaxis. In this article, we will explore why these functions may perform slower in JAX compared to NumPy and discuss best practices to optimize their usage. Understanding the Performance Discrepancy Why JAX May Be Slower for Basic Operations The performance of JAX can vary significantly depending on the operations being performed. While JAX is designed for efficient numerical computation and can excel in larger batch sizes and com…  ( 5 min )
    5 Common Workflow Automation Mistakes (And How to Avoid Them)
    Let’s not sugarcoat it—workflow automation should be simple. You sketch out a flow, wire up a few APIs, slap in a trigger, and boom: your job runs itself while you sip coffee. Except… not really. In reality, automation breaks. It misfires. It fails silently. And if you’re building workflows without a plan (I’ve done it), you’ll spend more time debugging than you ever saved. So here are 5 workflow automation mistakes I’ve run into—plus how I fixed them using Martini, a low-code automation platform that somehow gets it. 1. Only Building the Happy Path Raise your hand if you’ve built an automation that worked perfectly—until the first error. I’ve done it. Then I spent the next hour trying to figure out why a webhook timed out and brought down the entire flow. ✅ Fix: Build for failure first.…  ( 4 min )

    Bridging Brilliance and Blunder
    Beneath the noise of internet forums and viral memes, a fascinating reflection stares back at us. It juxtaposes artificial intelligence—consistent, precise, and relentlessly efficient—with what users affectionately term "natural stupidity," the charming catalogue of everyday human errors. This humorous contrast isn't merely jest; it captures the essence of our paradoxical relationship with the technology we ourselves have crafted. In recognising both our ingenuity and our imperfections, we frame a dialogue that reveals profound truths about humanity, technology, and our entwined destinies.

    How to Send Traces Using Scala and OpenTelemetry
    How to Send Traces Using Scala and OpenTelemetry When working with distributed systems, traceability is crucial for understanding system behavior. If you are using Scala and OpenTelemetry to send traces, you may encounter some challenges, particularly if your traces are not appearing in the tracing backend like Zipkin or Tempo. Why Might Traces Not Be Sent? Traces not appearing in your tracing backend can be attributed to several issues. These issues might stem from misconfiguration in your OpenTelemetry setup, lack of proper attributes, or even potential threading issues with Scala. It’s essential to verify that the OpenTelemetry collector is up and running and that the endpoint is correctly configured, which you have indicated is ready. In Scala, the ThreadLocal context propagation can b…  ( 5 min )

    Validate Your Env at Build Time — with Custom Rules Powered by Amazon Q Developer
    This is a submission for the Amazon Q Developer "Quack The Code" Challenge: Crushing the Command Line I created envguardr, a CLI tool that validates environment variables at build time. It’s useful for projects where .env files or runtime checks aren't enough. It handles types, required fields, and default values, but I felt it needed more flexibility. To address that, I enhanced the underlying validation package valitype by adding support for custom validators. This was one of the ideas suggested by Amazon Q Developer during the challenge. That single improvement unlocked a range of advanced use cases. Install envguardr globally: $ npm install -g envguardr Create an env.schema.js file with custom validation logic: module.exports = { API_KEY: { type: 'custom', validator: (v) => /^[a-z0-9]{16}$/.test(v || ''), errorMessage: 'API_KEY must be 16 alphanumeric characters', required: true } } Then run: $ envguardr validate env.schema.js envguardr with a custom schema validation for API_KEY: https://github.com/fontebasso/valitype https://github.com/fontebasso/envguardr This challenge was my first experience with Amazon Q Developer, and I was genuinely impressed. It’s exactly the kind of tool I always felt was missing for developers working with AI. Amazon Q Developer was able to read my codebase, understand its context, and assist in meaningful ways. It helped me improve typing, write better tests, fix subtle lint issues, and explore useful new features. From the several improvements it suggested for valitype, I chose to implement custom validators. That feature alone made envguardr much more powerful, giving it the flexibility needed for advanced configuration validation.  ( 3 min )

    What is the difference between Test_two and A_Package::Test_one in Perl?
    In Perl programming, naming conventions for symbol table entries can seem confusing at first glance, especially when we encounter entries like Test_two and A_Package::Test_one. In this article, we will explore the distinctions between these two styles of naming and how they impact the scope and accessibility of your subroutines. Understanding Symbol Tables in Perl In Perl, every package has its own symbol table, which serves as a collection of all the symbols (subroutines, variables, etc.) defined within that package. This allows for the organization of code into different namespaces, ensuring that subroutine names do not clobber each other in larger applications. The Significance of Test_two When we define a subroutine using the name Test_two, like this: *{"Test_two"} = sub{"Testing Two…  ( 4 min )

    How JavaScript Executes Code: Understanding Execution Context and the Call Stack
    JavaScript is a single-threaded, synchronous programming language at its core, but it handles asynchronous operations through clever mechanisms like the event loop. To truly understand how JavaScript works under the hood, you need to grasp two fundamental concepts: execution context and the call stack. An execution context is an abstract concept that holds information about the environment where JavaScript code is executed. There are three types of execution contexts in JavaScript: Global Execution Context: Created when the JavaScript engine first starts executing your code Function Execution Context: Created whenever a function is invoked Eval Execution Context: Created inside an eval function (rarely used) Each execution context has two phases: Creation phase Execution phase During the c…  ( 5 min )
    Internship Prep
    🚀 Stepping Into the Cloud: My First Tech Internship I’ll be working remotely as a Cloud Engineering Intern at a startup called Pledged. They’re doing some really cool work helping universities and colleges manage their partnerships with external companies. Basically, they give schools one simple platform to track and organize all their business relationships — no more messy spreadsheets. Think of it like a behind-the-scenes CRM for higher education, and I get to help build it. What’s even more exciting? The tech stack. I’ll be working with: TypeScript Tailwind CSS React Router Vite Node.js Docker Microsoft Azure Yes — full-stack cloud engineering with a taste of containerization and cloud infrastructure. I’ll be starting out on front-end tasks, but eventually I’ll get to dive into cloud stuff too. With all the buzz around cloud computing, I can’t wait to roll up my sleeves and get my hands dirty in Azure. 🧠 How I’m Preparing i took an IBM JavaScript course on Coursera. Followed a Scrimba course to brush up on my JS fundamentals. Built a few practice projects to get comfortable with React (since I’ve never used it before). Started learning TypeScript ,also new territory for me, but I'm determined to hit the ground running. 😅 The Honest Truth I’ve heard people say your first tech internship humbles you. That thought stays in the back of my mind, and it does freak me out a bit. What if I struggle? What if I fall behind? But here’s what I do know: I’m giving it everything I’ve got.

    Upgrade Your Angular Application Effectively!
    One task you may not do every day, but will eventually face as an Angular Developer, is updating your Angular application's version. At first glance, it may seem simple — especially since the official documentation provides a step-by-step guide. However, that guide won’t cover everything you’ll encounter during a real-world migration. In this post, I’ll share key tips to help you upgrade your Angular project more efficiently and avoid common pitfalls. Before starting any migration, it's essential to have a solid Git workflow. I recommend using a Git Flow strategy: Keep your main branch stable and production-ready. Create a dedicated migration branch (e.g., migration/angular-17). Every time changes are approved on main, merge them into your migration branch to keep it up to date. This allow…  ( 4 min )
    How to Export a Swift Package as an XCFramework

    How to Prevent, Predict, and Fix Relationship Conflicts
    You would think that a small comment you made about your partner's outfit does not mean anything. However, that small comment has the potential to become a trauma for your partner. In fact, any comment that comes out of your mouth has the potential to scar your partner for life. Therefore, it is important to know yourself, know the evil and good side of your personality, know when each of those are in command of your speech. This knowledge will in turn make you a safe space for your partner, and will also make you someone that is able to prevent conflicts; "If I am aware of my mood I am able to manipulate my speech". Predict conflicts; "If I am at my worst mood the words that come out of my mouth will be harmful". Fix conflicts "I said certain things while I was not at my best cognitive ab…  ( 4 min )

    Building Tools for ANT National Transit Authority Matrícula Data
    In Ecuador, public data systems are becoming increasingly accessible, and developers have a unique opportunity to create tools that make this data more user-friendly. One such system is the ANT matrícula, which allows individuals to check the legal status of a vehicle by entering its license plate. This system is crucial for verifying vehicle registration, ensuring that taxes are paid, and checking whether there are any fines or restrictions on a vehicle. While the ANT does not provide a public API, developers can still create tools that simulate this functionality. For instance, a backend system can be built using technologies like Node.js, where users can input a license plate number and receive data about its registration status. This not only helps users avoid scams when buying a used car but also assists businesses in managing vehicle fleets or ensuring compliance with national regulations. However, it's important to follow ethical guidelines when accessing public data. Developers should ensure that personal data is never stored without consent and that scraping or data collection is done in compliance with legal standards. Creating tools based on the ANT National Transit Authority matrícula system brings significant value to users, especially by saving them time and offering an easy way to confirm the legal status of a vehicle without having to visit government websites. By building accessible and useful tools, developers can support transparency, safety, and efficiency in Ecuador's transportation system.  ( 3 min )
    Secure, Swift, and Smart: A Basic Guide to Building AI Agentic Workflows with Local Models
    Artificial intelligence is transforming how we solve problems, but flagship models like GPT-4 come with drawbacks: high costs, latency, and privacy concerns when sensitive data leaves your network. Local models offer a powerful alternative—smaller, faster, and fully contained within your infrastructure. In this basic guide, we’ll walk through building an AI agentic workflow using a local 14B parameter model to create a SQL agent that autonomously handles database queries. This overview focuses on key concepts and best practices to make it efficient, reliable, and enterprise-ready. Local models require more setup than commercial APIs, often needing custom training to perform at their best, and they don’t match the broad intelligence of flagship models.

    The Design of Trust, or How a Game Designer Manipulates .
    I. Preface: «Guiding the blind (or pretending to be one?)» Do you enjoy being mistrusted? Think back to that feeling when you tackle a new, intriguing task — whether it’s assembling a complex model, solving a puzzle, or finding your way along an unfamiliar route—and someone hovers over your shoulder. They prompt every step, point out the obvious, never give you a chance to trip, to ponder, to find the solution on your own. Annoying, isn’t it? It feels as though they take you for a fool who can’t put two and two together without outside help. Perhaps I don’t understand something about life. Maybe today’s world really does demand maximum safety and the minimization of any effort or risk. But when I look at the game industry — especially its mainstream sector — I see a trend I’d call desig…  ( 55 min )

    Would a plug-and-play abuse protection toolkit be useful beyond Stripe Radar?
    Payment is one of the problems in online business and Stripe quick emerged as the main payment system despite seen a fair amount of complains. After Marc Louvion released ByeDispute, I was intrigued that Stripe was not covering that and so ended up having a tunnel on card fraud and how Stripe works. Yes Stripe Radar exists and cover some fraud cases but does not cover everything and there have been complains of account flagging despite it or a modification of the fraud detection algorithms that blocks all in coming transactions without any possibilities to stop that. But also fake signups, trial/refund cycling, scraping, or promo code abuse. Enterprise tools are overkill, and DIY solutions eat up dev time. So I wonder if a more general product that check One-trial-per-user, detect disposable email and scraping, have behavioral bot checks, prevent promo/referral abuse and chargeback/refund patterns, ... Would actually be more interesting. When flagging you would get the reasons and the solution can be disactivated at any time. Maybe even a community side with common ban list on fraudulent payments or disputes. On top of that a dashboard to follow all of this. Would something like this be helpful or just more noise? Curious if others have had to roll their own systems for this.  ( 3 min )

Use forward/back buttons to accelerate or reverse (north/south). Press a jump button to lift off ramps (up/down). A race timer shows elapsed time, counting forward only. Definition: Distinct properties required to describe an entity fully. 4D Illustration: Four attributes defining a profile. Analogy: A game character defined by Strength, Agility, Intelligence, and Charisma. The vector (7,5,9,3) conveys the complete trait set instantly. 2. Time as the Fourth Dimension Adapting Each Model to Include Time: Physical View Analogy: Characteristic View Analogy: 3. What Does a 2D Vector Represent?

    Centralize HTTP Error Handling in Go
    Originally posted here In this short post, I'll share with you a simple pattern I use to centralize error handling for my HTTP handlers. If you've written any amount of Go HTTP servers, you've probably gotten tired of writing the same error handling code over and over again: func SomeHandler(w http.ResponseWriter, r *http.Request) { data, err := fetchSomeData() if err != nil { http.Error(w, "Failed to fetch data", http.StatusInternalServerError) log.Printf("Error fetching data: %v", err) return } // More if-err blocks... } This code is repetitive, error-prone, and clutters your handlers with boilerplate instead of business logic.

If you scroll down to the bottom of that page, you’ll see a list of the books that I’ve published. You’ll also see evidence of the problem I’ve been solving this morning. Books tend to have covers that are in a portrait aspect ratio. But the template I’m using to display them requires images in a landscape aspect ratio. This is a common enough problem. And, of course, we’ve developed a common way of getting around it. You’ll see it on that page. We create a larger version of the image (large enough to fill the width of where the image is displayed), apply some level of Gaussian blur to the image and insert a new copy of the i…  ( 5 min )
    Singleton Design Pattern: Explained Simply
    In software design, some objects are meant to be shared across the entire application. Think of a configuration manager, a database connection, or a logger. You don’t want to create multiple instances of these — just one that is reused everywhere. That’s exactly where the Singleton Pattern comes in. The Singleton Pattern ensures that a class has only one instance and provides a global point of access to it. It’s part of the Creational Design Patterns — patterns focused on object creation. Think of a government. There’s only one Prime Minister (ideally 😄). If you try to create a new one, it should refer to the existing one. Database connections Logging services Config/environment managers Thread pools Caching mechanisms class Singleton { constructor() { if (Singleton.instance) { return Singleton.instance; } this.timestamp = new Date(); Singleton.instance = this; } getTime() { return this.timestamp; } } // Usage const a = new Singleton(); const b = new Singleton(); console.log(a === b); // true console.log(a.getTime() === b.getTime()); // true class Singleton: _instance = None def __new__(cls): if cls._instance is None: cls._instance = super(Singleton, cls).__new__(cls) cls._instance.timestamp = "Created at instance creation" return cls._instance # Usage a = Singleton() b = Singleton() print(a is b) # True Controlled access to a single instance Saves memory (especially useful for expensive objects) Can be lazily loaded (created only when needed) Global state can be hard to test Can violate Single Responsibility Principle In multithreading environments, needs proper locking (especially in Java/C++) Keep it stateless if possible Avoid abusing it like a global variable Be cautious in multi-threaded apps (use locks/mutexes) The Singleton Pattern is a handy tool when you need exactly one instance of a class to coordinate actions across the system. Use it wisely and you’ll make your application more efficient and structured.  ( 3 min )

    How to Fix Dropdown Button Issues After Modal Closure?
    Introduction Are you experiencing issues with a dropdown button that doesn't work after closing a modal window? If your dropdown menu fails to function immediately after a modal closing action and only starts working after reopening the modal, this article is meant for you. We'll delve into the possible causes of this problem and suggest practical solutions to ensure your dropdown works seamlessly. Understanding the Problem The issue at hand often arises due to JavaScript event handling conflicts, particularly with the Bootstrap framework. When a modal is opened, some elements within the modal may interfere with event listeners intended for buttons outside of it. This can lead to inconsistent behavior, where the dropdown button only works after a second modal closure, suggesting that the D…  ( 4 min )
    How I Set Up Prometheus and Grafana Monitoring on AKS from Scratch
    Setting up a monitoring stack in Kubernetes can be overwhelming if you're doing it for the first time. When I started working with Azure Kubernetes Service (AKS), I realized I needed better visibility into pod and node metrics — that’s when I turned to Prometheus and Grafana. In this post, I’ll walk you through the exact steps I took to get Prometheus and Grafana running on AKS, along with some lessons I learned along the way. ## 🔧 Why Prometheus + Grafana? Prometheus scrapes and stores time-series data from Kubernetes. Grafana gives you beautiful, customizable dashboards. Together, they provide powerful insights into your cluster’s performance. ## 🛠️ Prerequisites Azure CLI installed and authenticated kubectl configured to your AKS cluster Helm 3 installed A working AKS cluster bash helm repo add prometheus-community https://prometheus-community.github.io/helm-charts helm repo add grafana https://grafana.github.io/helm-charts helm repo update **Install Prometheus:** helm install prometheus prometheus-community/prometheus \ --namespace monitoring --create-namespace Install Grafana: helm install grafana grafana/grafana \ --namespace monitoring Access the Grafana UI: You can port-forward and access Grafana at http://localhost:3000: kubectl port-forward svc/grafana 3000:80 -n monitoring **Login using:** Username: admin Password: (from step 4) **📊 Importing Dashboards** Once inside Grafana, go to "Dashboards > Import" and use IDs from Grafana.com like: Kubernetes Cluster Monitoring: 315 Node Exporter: 1860 **💡 Lessons Learned** Always install Prometheus before Grafana if you want dashboards to auto-discover data sources. Use persistent volumes for Prometheus and Grafana in production. Set up alerts for critical metrics like pod restarts or high CPU usage. I’m planning to extend this by: Setting up AlertManager Integrating with Slack for alerts Enabling SSL and Ingress for Grafana Stay tuned! 👀  ( 3 min )

    What is redis pipeline
    Introduction Redis is a fast, in-memory data store widely used for caching, message brokering, and real-time analytics. While Redis is incredibly efficient, network overhead can become a bottleneck when a large number of commands are sent sequentially. This is where Redis pipelining comes in. Redis pipelining allows a client to send multiple commands to the server without waiting for individual responses. The server processes the batch of commands and returns all responses in a single reply, significantly reducing the latency caused by round-trip communication. If you are struggling to remember redis commands then this cheatsheet might help you. Redis pipelining offers several advantages: Reduced Latency: By sending multiple commands in a single request, you cut down on network round-tri…  ( 4 min )

    Gland: Beyond Protocol-Agnostic
    Hey everyone, I’m back again with another update from the world of Gland — and this one is kinda big for me. So far, I’ve talked a lot about Gland being protocol-agnostic. But recently, something shifted. Gland is not just protocol-agnostic anymore — it’s kinda framework-agnostic too. What does that even mean? Let’s be real: right now Gland doesn’t care whether you're using Express, Fastify, Hono, or literally anything else that can act like an HTTP server. You can swap them in and out with minimal effort. And I’m not talking about some theoretical plug-and-play thing. I mean actual working code. Take this simple example: glandjs/gland/main/samples/01-simple/src/main.ts In this setup, I’m using Express. But if you want Fastify instead?

    Goodbye pod install
    Introduction For years, React Native developers working on iOS have relied on one command more than any other: cd ios && pod install This command has been a staple for managing native dependencies in iOS projects. But in 2025, React Native is moving away from it—and for good reasons. If you’ve recently seen a warning like: "Calling pod install directly is deprecated in React Native" ...you’re witnessing a significant shift in how React Native handles iOS builds. React Native is undergoing a significant transformation, and part of that involves reducing reliance on iOS-specific tools like CocoaPods. Here’s why: CocoaPods is great for iOS, but React Native aims for true cross-platform development. The new architecture favors tools that work seamlessly across iOS, Android, and beyond.

    How to Find the Second Highest Student Average Mark in Java?
    Finding the second highest average mark among students can be a common requirement in many applications that deal with student data. In this article, we will explore a solution to find the student with the second highest average mark without creating any new objects. We will be using Java streams and our custom Student class, which holds information about each student such as their average mark, first name, last name, and date of birth. Understanding the Problem To tackle this problem, we need to follow a few key steps. First, we need to sort the list of students based on their averageMark. Since we want to find the second highest average mark, it is essential to sort the list in descending order. According to the problem's requirements, if two students have the same average mark, we shoul…  ( 4 min )
    I love finite-state machines:)
    Hi, my name is Anton. I'm a software developer specializing in cross-platform mobile development, currently working at a fintech company where I help build a neo-banking application. There's often debate about design patterns—do we really need them, or are they just outdated theory with little practical value in modern software development? I strongly disagree with the idea that patterns are unnecessary. In my view, having a solid foundation in theoretical concepts is extremely valuable. It's like recursion: you might not need it every day, but when you encounter a problem that is recursive in nature—like traversing a file system—you simply can't solve it effectively any other way. The same applies to design patterns. Some processes naturally fit certain patterns, and recognizing them allo…  ( 9 min )
    The Great MCP Aggregation Heist
    How Your Code Became Someone Else’s Goldmine In the thickening jungle of AI innovation, Model Context Protocol (MCP) aggregation services are rising like monolithic temples, promising universal access to tools and automation.

Dig just below, however, and an unsettling reality emerges: these aggregators are monetising the sweat, intellect, and creative risk of thousands, sometimes millions, of individual developers. The winds have changed. Your code—once a byword for progress—has become just another commodity, fuelling centralised profit with little return for its creators. This is the story of a digital gold rush where the diggers now find themselves locked out of the vault. Remember the wild dawn of open source, when so…  ( 9 min )
    Programming language of the future Part 3: OOP
    We want to manage state, by dividing it into units and giving them a name. Attaching behavior to them is also a good option - and thus we have OOP. But let's not adopt it blindly - a critical examination is in order. OOP is there to promote Encapsulation, Polymorphism, Abstraction. What would be the optimal way of providing them? Encapsulation means exposing only as much information about the object as necessary to provide the service. All of the information that is exposed and used by clients, if it were to be changed, means that either the client has to change at the same time - or versioning would need to take place. This idea makes sense, and for a language to support it, it would need ways to mark visibility of fields and methods. Polymorphism means for the same object to exhibit diff…  ( 5 min )

    The Evolution of the Phrase “Click Here”: From Web Staple to Obsolete
    The phrase “Click here” was once a cornerstone of internet navigation. It was ubiquitous across websites, often used as a direct instruction to users: simply click a link, button, or piece of text, and something new would unfold—whether it was a download, a page redirect, or a pop-up. In the early days of the internet, this phrase was essential, helping users navigate a relatively new and confusing online landscape. But today, “Click here” is seen as a relic, a remnant of simpler times that no longer meets the standards of modern web design and user expectations. In this article, we will examine how “Click here” came to prominence, why it has lost its relevance, and the evolution of web design that has led to the adoption of more sophisticated, user-centered alternatives.

    Concurrency in Go
    ❓ What is Concurrency? Concurrency is the ability of a program to manage multiple tasks at once. These tasks may not run exactly at the same time, but they are managed in such a way that it feels like they are happening simultaneously. Imagine you’re cooking dinner: You put water on the stove to boil. While the water heats up, you chop vegetables. Once it’s boiling, you add pasta. While pasta cooks, you prepare the sauce. You are switching between tasks. You're not doing everything at once, but you're switching between tasks efficiently to save time. That’s concurrency: smart multitasking, not true parallelism (which involves tasks running at the exact same time on multiple CPU cores) In Go, concurrency means: Your program runs multiple tasks (functions or processes).

    What is UDP? Understanding the “Unreliable” Transport Protocol
    When you send a message over the internet—whether it’s a cat meme, a video stream, or a DNS lookup—it’s traveling through layers of protocols. Two of the most important transport-layer protocols in this stack are TCP and UDP. While TCP gets a lot of the spotlight thanks to its reliability and widespread use in web traffic, UDP (User Datagram Protocol) is the unsung hero behind many real-time and low-latency applications. In this post, we’ll demystify what UDP is, how it works, and why developers choose it despite its nickname: the "Unreliable Datagram Protocol." UDP is one of the core protocols of the Internet Protocol (IP) suite. It was introduced in 1980 as a lightweight alternative to TCP. UDP operates on top of IP and is used to send short messages called datagrams. The key difference?…  ( 4 min )

    鸿蒙跨平台开发教程之Uniapp布局基础
    前两天的文章内容对uniapp开发鸿蒙应用做了一些详细的介绍,包括配置开发环境和项目结构目录解读,今天我们正式开始写代码。 入门新的开发语言往往从Hello World开始,Uniapp的初始化项目中已经写好了一个简单的demo,这里就不再赘述,我们直接从布局开始说起。 Uniapp的布局方式和鸿蒙原生语言ArkTs有所不同,但又颇为神似。 幽蓝君之前总结过,所有的布局方式无非只有三种,横向、竖向和层叠,其他所有的布局方式都由这三种衍生而来,Uniapp也不例外。 ArkTs中有Row()、Column()、Stack()、Flex()这几个基础的布局容器组件,更复杂一些的还有像List()、Grid()、Scroll()等等。 而在Uniapp中,基础的布局方式我们通常直接使用view容器来实现。比如我想要实现一个横向的布局,使用view容器,在view的样式中设置布局方式为row: 而到了纵向布局,只需要把布局方向设置column就行了: 接下来比较难的部分到了,对于层叠布局,ArkTs直接提供了Stack()容器,并且有对应的对齐方式可以直接设置,比较简单。但是uniapp并没有提供这种对齐方式,flex-direction中是不能直接设置层叠布局的。 我们可以使用postion属性来实现。postion的作用是设置定位方式,有static、relative、fixed、absolute集中方式,我们今天要说的是absolute。 absolute是一种绝对定位方式,是脱离了文档流、相对于父元素的绝对定位方式。 更详细一点解释就是不管它有多少同级别的组件,都不影响它以父元素左上角为原点的定位,同样的它也不影响别人,相当于悬浮在上层,使用偏移量来控制位置。比如下面这段代码: 所以如果需要层叠布局的两个容器都使用absolute定位,并且使用top、left、bottom、right来设置对齐方式,就实现了鸿蒙中的Stack()一样的功能: 这里可以使用z-index来设置谁在上一层,另外,绝对定位的父容器需要设置position: relative属性,否则子组件无法找到目标。 以上就是Uniapp开发鸿蒙的基础布局方式,感谢您的阅读。  ( 3 min )

    How to Implement a Custom WeighedBlockingCollection in C#
    Introduction to BlockingCollection and Memory Management In C#, the BlockingCollection class is a powerful tool for handling producer/consumer scenarios in a thread-safe way. However, when dealing with large objects that can vary in size significantly—like the ones you mentioned ranging from 10 MB to 700 MB—it's crucial to manage memory effectively to avoid OutOfMemoryExceptions. To achieve this, we need a customized collection that extends the functionality of BlockingCollection by allowing us to limit the total memory used by the items stored in it. Understanding the WeighedBlockingCollection The goal here is to create a custom collection called WeighedBlockingCollection, which will not only mimic the behavior of BlockingCollection but also impose a weight restriction on the …  ( 5 min )

    Mastering TypeScript: Union Types & Type Aliases Explained
    TypeScript offers powerful tools that help you write clean, scalable, and type-safe code. Two of the most useful features in this toolkit are Union Types and Type Aliases. In my latest YouTube video, I break down how to use these features effectively—even if you're just getting started with TypeScript. ✅ What You'll Learn ✅ What is a Union Type in TypeScript? ✅ How to use Union Types with function parameters ✅ What is a Type Alias and how to use it ✅ How to combine Union Types and Aliases ✅ Real-world use cases and code walkthroughs ✅ Common mistakes to avoid If you've ever found yourself repeating types or making your code harder to read, Union Types let you define a variable that accepts multiple types: let id: string | number; Meanwhile, Type Aliases allow you to give a custom name to a type: type ID = string | number; function printId(id: ID) { console.log("Your ID is:", id); } Combined, they make your code more readable, reusable, and easier to maintain. type SuccessResponse = { status: "success"; data: string; }; type ErrorResponse = { status: "error"; error: string; }; type APIResponse = SuccessResponse | ErrorResponse; function handleResponse(res: APIResponse) { if (res.status === "success") { console.log(res.data); } else { console.error(res.error); } } This is a clean, scalable way to handle multiple response types from an API. I walk you through all this and more in the full tutorial on YouTube: 👉 Watch on YouTube Whether you're building a small project or working with a large team, learning how to use Union Types and Type Aliases will make your TypeScript code more maintainable and developer-friendly.

    My Second Month as an LFX Mentee: Advancing Microcks Deployments
    Hello everyone! It’s been another productive month in the LFX Mentorship program with the CNCF Microcks project. This month, I focused on enhancing Microcks deployments on Google Kubernetes Engine (GKE) and improving documentation for cloud-specific deployment strategies. Additionally, I had the opportunity to present my contributions during the community meeting, where I encouraged others to contribute, provide feedback, and review the documentation. Asynchronous Options on GKE I worked on improving the Microcks GKE deployment by adding support for asynchronous protocols and securing the Microcks endpoint with TLS. Enabled Kafka-based async protocols with Helm and installed Strimzi for Kafka management. Secured the endpoint using cert-manager and Let's Encrypt for automatic SSL certificate provisioning. Deploying complex systems like Microcks with external Keycloak and MongoDB can sometimes lead to roadblocks. To address this, I created a TROUBLESHOOTING.md file in the repository. This document provides a set of common issues and solutions that developers may encounter when deploying Microcks on GKE, especially when integrating with Keycloak for authentication and MongoDB for data storage. Troubleshooting Guide I developed a GUIDELINES.md document that outlines the deployment process for Microcks across multiple cloud providers. The guidelines cover setting up infrastructure, deploying Keycloak, provisioning databases, and configuring Microcks with Helm. Common Guidelines Next month, I plan to: Deploy Microcks on Azure AKS and document the process. Add a Troubleshooting Guide for Azure deployment. Month two has been an exciting journey, contributing to Microcks with improvements in deployment, security, and cloud-specific guidelines. I’m excited to continue supporting the Microcks community and look forward to the next steps! Feel free to check out my contributions on the Microcks community repository  -  feedback and contributions are always welcome! See you in the next update! 👋  ( 3 min )

    Understanding JSON in JavaScript: A Complete Guide
    JSON (JavaScript Object Notation) is a lightweight data-interchange format that's easy for humans to read and write and easy for machines to parse and generate. It's one of the most widely used formats in web development, especially when working with APIs and server responses. JSON is a text-based format for representing structured data. It resembles JavaScript object syntax, but it's a string. Example JSON: { "name": "Alice", "age": 25, "isStudent": false, "skills": ["HTML", "CSS", "JavaScript"] } They look similar, but they are different: Feature JavaScript Object JSON Data Type Object String Can contain functions Yes No Comments Allowed Not allowed Quotes on keys Optional Mandatory JSON.stringify() Converts a JavaScript object into a JSON string. const user = { name: "Bob", age: 30 }; const jsonString = JSON.stringify(user); console.log(jsonString); // '{"name":"Bob","age":30}' JSON.parse() Converts a JSON string back into a JavaScript object. const jsonString = '{"name":"Bob","age":30}'; const user = JSON.parse(jsonString); console.log(user.name); // 'Bob' fetch('https://api.example.com/data') .then(response => response.json()) .then(data => { console.log(data); // Parsed JSON object }); Most APIs return JSON. Using .json() parses the response body into a JavaScript object. Forgetting to wrap keys in quotes in JSON: { name: "John" } // Invalid Correct: { "name": "John" } Using functions in JSON: JSON.stringify({ sayHi: () => "Hi" }); // sayHi will be removed JSON is used for storing and exchanging data. Use JSON.stringify() to convert objects to strings. Use JSON.parse() to convert strings to objects. It’s widely used in API communication.

    Stop Overengineering in the Name of Clean Architecture
    Clean Architecture is a great concept. It’s meant to help you write maintainable, modular, and scalable software. But too many developers treat it like a religion. They follow it blindly, stuffing projects with unnecessary layers, abstractions, and patterns. All in the name of “clean code.” Let’s be honest, Clean Architecture is often overused, not because the ideas are bad, but because people overengineer the implementation. Here’s an example of multiplying two numbers implemented with an absurd number of patterns: // overengineered-multiplier.ts // Interface interface IMultiplier { multiply(a: number, b: number): number; } // Singleton class MultiplierService implements IMultiplier { private static instance: MultiplierService; private constructor() {} static getInstance(): Mu…  ( 5 min )

    AI agents are coming for DeFi — Wallets are the weakest link
    Opinion by: Sean Li, co-founder of Magic Labs Crypto markets run 24/7. Human traders don’t. As AI agents begin to manage liquidity, optimize yield, and execute trades at all hours, they’re quickly becoming essential infrastructure for decentralized finance’s (DeFi) future. While AI agents are evolving from niche tools for quant traders into mainstream financial operators, they’re rapidly outpacing the wallets meant to secure them.  Advancements in account abstraction and smart contract wallets have emerged, but most DeFi platforms still predominately rely on externally owned account wallets that require manual approvals at every step. Early-stage programmable solutions exist but remain fragmented, costly on layer-1 networks and adopted by only a tiny fraction of users. As AI agents increas…

    Pectra lets hackers drain wallets with just an offchain signature
    Ethereum’s latest network upgrade, Pectra, introduced powerful new features aimed at improving scalability and smart account functionality — but it also opened a dangerous new attack vector that could allow hackers to drain funds from user wallets using only an offchain signature. Under the Pectra upgrade, which went live on May 7 at epoch 364032, attackers can exploit a new transaction type to take control of externally owned accounts (EOAs) without requiring the user to sign an onchain transaction. Arda Usman, a Solidity smart contract auditor, confirmed to Cointelegraph that “it becomes possible for an attacker to drain an EOA’s funds using only an offchain signed message (no direct onchain transaction signed by the user).” At the center of the risk is EIP-7702, a core component of the …

    Altseason is coming, 40% daily gains to become ‘new normal’ — Analyst
    Altcoin markets are flashing early signs of a breakout, with several analysts calling for a potential surge over the next few months. Crypto commentator Mister Crypto predicts the next 3 to 6 months could be “life-changing,” suggesting daily gains of up to 40% may soon become the norm. In a May 11 post on X, he pointed to a chart from BlockchainCenter.net that shows whether the crypto market favors Bitcoin (BTC) or altcoins. When the index is below 25, it’s considered “Bitcoin Season,” meaning Bitcoin is outperforming most altcoins. When it’s above 75, it’s “Altcoin Season,” meaning altcoins are doing better than Bitcoin. Currently, the chart shows a breakout from a downward trend just below the 29 mark, suggesting a possible shift away from Bitcoin dominance. This breakout hints that altc…

    Declarative FullStack: Shifting Backend Ownership to the Frontend
    Abstract Introduction The conventional model of web application development separates frontend and backend responsibilities into different teams, skillsets, and codebases. Frontend developers manage UI and client-side logic, while backend developers handle server-side processing, API creation, data storage, and security enforcement. However, this division can lead to longer development cycles, coordination challenges, and duplicated logic across layers. A new paradigm is emerging—one in which frontend developers can declaratively define backend logic using frontend tools and syntax. This shift is enabled by modern platforms that offer serverless scalability, secure permission management, and efficient request/response handling under the hood. This approach doesn't eliminate the need for ba…  ( 5 min )
    What is the Difference Between UDF and Vector UDF in Spark 3?

    How to Manage Departments and Users in C# EF Core
    Introduction When working with Entity Framework Core (EF Core) in C#, managing relationships between entities is crucial. In this scenario, we have a case where a department can have multiple users, and when a user is assigned a new department, we need to ensure the previous department is deleted if it has no users left. This is a common requirement in applications that handle organizational structures. Why the Department Query Might Not Reflect Updates In your situation, you are attempting to update a user's department and then immediately check if the previous department has users left. You notice that even though the update reflects in the database, the department load returns stale data. This issue can arise due to EF Core’s change tracking behavior and how it interacts with the databa…  ( 5 min )
    How to Use Libuv In Your Zig Project
    Libuv describes itself as a multi-platform support library with a focus on asynchronous I/O. It is widely used in many web servers (e.g., Kestrel) and runtimes such as Node.js and Python (via uvloop). As of Zig 0.14.0, there is no native async I/O, so you must work directly with threads or create your own async API using OS primitives like epoll or kqueue. In many cases, you would likely choose a cross-platform library rather than implementing your own async API. That’s where using libuv, libevent, or libxev (written in Zig) becomes useful. This guide will show you how to use libuv from your Zig project. I’ll start with a basic Zig project to demonstrate how this works. It will be a simple app that runs some timers. We’re going to use the package from github.com/allyourcodebase/libuv to bu…  ( 5 min )

    Real-time Deepfakes: what if "seeing is believing" no longer means anything?
    An open-source project called Deep-Live-Cam is gaining traction on GitHub — and for good reason. With just a single still image, it can mimic anyone’s face in a live video call. In real-time. Running locally. No cloud required. The implication is clear: you can no longer trust a video call at face value. So here’s the question: how do we verify identity in a world where faces can be forged on demand? While many react with fear or disbelief, I see only one viable answer: digital signatures. For years, I’ve been saying: we should encrypt everything — files, messages, infrastructure. But now, that’s not enough. We need to start signing everything. Digital signatures ensure authenticity. They prove that something really came from who claims to have sent it and hasn’t been tampered with. We already sign emails, source code, and software packages. Why not apply the same principle to real-time streams? Imagine a video call cryptographically signed with the speaker’s GPG key. Even if the face looks convincing, if the signature doesn’t verify, you know something’s off. I sign every HTML page on my personal website with my GPG key. Not because I’m paranoid — but because I believe security should be a mindset. Don’t trust. Verify.  ( 3 min )
    How to Update a Progress Bar in MantineReactTable using WebSocket?
    Introduction In modern web applications, displaying real-time data is crucial, especially for user engagement. In this article, we'll explore how to effectively update a progress bar within a table using the MantineReactTable component in a React application. The focus is on integrating WebSockets to receive progress updates without causing unnecessary re-renders. Understanding the Challenge You might be facing an issue where your progress bar component does not rerender despite the state updates from useState. This can be confusing, especially when the console confirms that the state is updating. The problem often resides in how Reac's reconciliation process manages component updates and how state is propagated to child components.

    Solving "SDK 'Microsoft.NET.Sdk' Not Found" Error in Visual Studio
    If you're learning C# or .NET development, you might encounter this frustrating error: One or more errors were encountered while creating project ConsoleApp3. The generated project content may be incomplete. The SDK 'Microsoft.NET.Sdk' specified could not be found. I faced exactly this issue during my early days learning C#. After multiple attempts, I finally found a solution that worked reliably for me: The root cause appears to be that the official .NET SDK installer sometimes doesn't correctly set up the SDK on your system. Even after installation, the command dotnet --list-sdks might return an empty list, which indicates the SDK isn't properly recognized by your system. Here's what worked for me: Download the Binaries Manually: Go to the official .NET SDK downloads page. Instead of downloading the installer, choose the "Binaries" option. This will give you a .zip file containing the SDK files directly. Extract and Copy Files: Extract the downloaded .zip file to a temporary location. Replace SDK Contents: Navigate to: C:\Program Files (x86)\dotnet\ Delete or back up existing contents, then paste the newly extracted SDK binaries into this folder. Verify Installation: Open a new Command Prompt or PowerShell window and run: dotnet --info You should now see details about the SDK and runtime versions installed. This solution manually ensures that the SDK files are correctly placed and recognised by your system, bypassing the potential issues caused by the automated installer.

    How to Call gRPC Methods Dynamically in Go
    gRPC (Google Remote Procedure Call) is a high-performance, open-source framework for making remote procedure calls. Unlike traditional REST APIs that use HTTP/1.1 and JSON, gRPC leverages HTTP/2 and Protocol Buffers for more efficient communication between distributed systems. This modern approach offers significant advantages in terms of performance, type safety, and code generation capabilities. When working with gRPC, you need to understand the fundamental components and workflow that differentiate it from other API communication methods. The process begins with defining your service interface using Protocol Buffers (protobuf) in a proto file, which serves as a contract between client and server. This definition is then compiled into language-specific code that handles all the underlyin…  ( 5 min )

    🎁 Kickstart Your Next Big Project with These GitHub GIFTS 🎁 🚀 300+ Open Source LLM Projects You Can Clone, Learn, or Monetize. 🎁 🔥 200+ Python Projects from Hacker News — GITHUB Bundle for Builders 👉 Perfect for indie hackers, developers, and solopreneurs looking for actionable repositories you can turn into products, experiments, or profitable tools. A week ago, I did something slightly unhinged: reads, modifies, and rewrites itself while it's running. Not some weird meta joke — I mean the actual .js file mutates its own content based on how it's used. And yes... it works. I was tired of manually tracking how often certain functions were used. I could’ve used telemetry, logging, whatever. But I thought: "What if the code just kept track of itself — in itself?" Imagine a function…  ( 6 min )
    Why does Bash not continue to the next iteration as expected?
    Introduction Have you ever faced an unexpected behavior in your Bash scripts, particularly regarding loops? In this article, we will delve into a common issue with the continue statement in Bash, as illustrated by your provided script. You're correct in observing that the continue statement should skip the remaining commands in the loop and jump to the next iteration. So, why isn’t it working as expected in your case? Understanding the Issue The primary reason the continue statement may not be functioning as you expected lies in the structure of your loop and the way Bash interprets commands. A common mistake is how command substitutions and pipes are handled in Bash scripts. When you use a pipe (|), the commands are run in separate subshells. This means the continue statement is scoped to…  ( 4 min )
    How Angular Schematics Help Developers Scale Architecture and Team Efficiency
    As software engineers, our job isn't just writing features or fixing bugs. We're responsible for improving the processes around software and help teams move faster, safer, and more consistently. That means asking questions like: Can we reduce repetitive tasks? Can we encode best practices so new team members don't guess? Can we lower the mental load of starting new features? For Angular projects, Schematics is one of the best tools to operationalize these improvements. It lets you automate architecture, encode standards, and enforce patterns. A schematic in Angular is a set of instructions that tells the Angular CLI how to generate or transform code. Think of it as a script that can: Create new files using templates. Update existing code (e.g. add a component to a module). Enforce consiste…  ( 4 min )

    I Built an AI Platform That Lets You Create Your Digital Twin — Here's How It Works
    Hi devs — I recently launched a platform called aimodeling.me, and I’d love to share what it does, how it works, and why I built it. In short, it lets you create a realistic AI model of yourself — your own "digital twin" — from just a few selfies. After that, you can generate endless photorealistic images of you in any scenario, outfit, or setting you can describe. We’re all used to AI image generators now, but most of them produce generic faces or imaginary people. I thought: what if we flipped that? What if you could put yourself in those scenes? Professional photoshoots are expensive, awkward, and static. I wanted a way to generate high-quality, personalized photos for myself (for social media, bios, content creation, etc.) without constantly needing to step in front of a camera. So I b…  ( 4 min )

    209/365 | ¥10M Job Challenge - Tied Down in Japan
    Working in Japan under the constraints of a work visa means there’s really not much you can do besides your day job. About the only other option is saving money and investing through NISA... Even if your company allows side jobs, you still need to apply for “Permission to Engage in Activity Other Than That Permitted Under the Status of Residence,” and possibly register and communicate with the authorities. Just thinking about all that paperwork makes me not want to bother. After all, the main goal is to build a life where I can live long-term in a place I truly want to be — for me, that’s Japan. So in reality, my daily life basically revolves around working and studying to prepare for a career move. I won’t deny that this kind of routine gets a bit dull over time. I just want a little more freedom, especially since both language learning and job hunting take so much time. Anyway, I need to hit my goal as soon as possible so I can finally enjoy the freedom I want in Japan!  ( 3 min )

    Simplify Your Cypress Intercept Assertions: cypress-intercept-search
    When writing end-to-end tests with Cypress, you must often validate that your application sends or receives the correct data. Cypress’s cy.intercept() gives you robust control over network requests. However, digging through nested bodies, headers, and query parameters to find the exact key/value you care about can become repetitive and error-prone. That’s why I created cypress-intercept-search, a small plugin that lets you recursively search through every part of one or more intercepted requests or responses for a given key and (optionally) a matching value. Then, wrap the results in a chainable Cypress command for easy assertions. ## Why Built cypress-intercept-search cy.wait('@savePlay').then((i) => { const { players } = i.request.body; expect(players).to.exist; Object.entries(play…  ( 4 min )

I will try to cover some of the things that you should follow for make your first project journey more smooth. Folder Structure: The first thing you might face difficulties is creating and understand the folder structure. It may vary by project to project, but their are some common concept like creating 2 separate folder, one for frontend and other one is for backend. Inside each folder you will have multiple folders. For backend you will have folders like models, services, api endpoints etc (based on your requirements) . And for frontend, you will have src folder inside which you will find components, assets, pages, api, utils etc folders (if you are using React). fullstack-project/ Make sure you must write code as clean as possible. It is a good practice. You should right the logics more efficient way. You can also create a folder for a particular module and inside that you can create multiple files so that anyone can easily find the code written for a specific purpose. It will reduce cognitive complexity. Another thing you should remember that don't make a function so large with so much logics in a single function, rather use multiple functions, each for a particular logic and use them in that function. Before writing any routes, you should always first do some floor planning like how this routes is going to use, how many times this routes will be called. It is completely necessary when you are going to deploying the project into the server. Because the more api needs to call from backend, the more it will take time to load and resulting the website slow. Wish a happy journey for your first project 😄 and share if you find this post helpful.  ( 4 min )
    Postman Was My Therapist: How I Finally Mastered APIs by Talking to Them Directly
    Have you ever felt like you're fighting with your own APIs? As a backend developer, I sure did... until I learned to stop debugging through the frontend and start talking directly to my APIs instead. Last month, I was building a backend for a mocktail ordering system. Everything was in place: // Our beautiful API endpoints app.post('/api/auth/register', registerUser); app.get('/api/auth/logout', logoutUser); app.get('/api/products', getProducts); app.post('/api/events', createEvent); app.post('/api/orders', createOrder); app.get('/api/invoices', getInvoices); app.get('/api/payments/history', getPaymentHistory); app.delete('/api/users/:id', deleteUser); Then the moment of truth came: testing the "Delete Account" feature.

    Programming language of the future. Part 2: State management
    Most programmers will agree that state management is a pain (in the head). Which is why they shy away from it at every opportunity. Languages, functional or OOP, make no difference - if state is only ever passed around to and from the database, it's all practically stateless in my book. In the industry-accepted programming model (clean model, layered model, hexagonal model) state management (database I/O) is on the outer layer - why? Oh, because you don't actually operate on entities that you store, you operate on transient entities derived from them. This abstraction is necessary, because in most modern languages state is carried by objects - and you can't store objects, only things derived from them. Be it rows in tables, or at least whole aggregates in NoSQL DBs. Actual object state can…  ( 4 min )

    Building true distributed systems with RoadRunner and Laravel
    I've been developing PHP applications for over 15 years now, working with various PHP frameworks. Throughout this journey, I've witnessed many projects that began as monoliths eventually need to evolve into microservices. That's when interesting architectural challenges emerge. While I'd successfully used RoadRunner (RR) with Spiral and Symfony before, I wanted to bring these same capabilities to my Laravel projects. Yes, Laravel Octane does provide RR integration but only for HTTP. I needed the full ecosystem of plugins that make RR truly powerful for distributed systems.

    🔐 Stop hardcoding secrets: generate `.env` files from AWS SSM with a simple CLI
    At M47 Labs, we work on many AI and cloud-native projects where secret management becomes complex — especially across environments and CI/CD pipelines. We're big fans of AWS SSM for storing configuration and secrets securely, but syncing them into .env files can be painful and repetitive. To solve this in a cleaner and more reliable way, I built a CLI tool: 👉 Envilder on GitHub Envilder reads a mapping file that links environment variable names to AWS SSM parameter paths. .env file. Your param-map.json might look like this: { "DB_HOST": "/my-app/dev/DB_HOST", "DB_PASSWORD": "/my-app/dev/DB_PASSWORD" } Run: envilder --map=param-map.json --envfile=.env And you get: DB_HOST=mydb.cluster-xyz.rds.amazonaws.com DB_PASSWORD=supersecret You can also use different AWS CLI profiles: AWS_PROFILE=staging envilder --map=param-map.json --envfile=.env This small tool makes a big difference when: 🧑‍💻 Onboarding new team members: no more “what’s the DB password?” 🔄 Keeping environments in sync: any change in SSM is reflected across the team ⚙️ CI/CD pipelines always up-to-date: e.g. GitHub Actions, CodeBuild, GitLab 🧼 Centralized configuration: avoid duplication and keep secrets in one secure place 🧭 Supports multiple AWS profiles: ideal for multi-account or multi-env setups Works with SecureString and plain parameters CLI-first, fast, and script-friendly Compatible with any CI system Supports static values and fallbacks AWS profile support (AWS_PROFILE) npm install -g envilder Or: envilder --map=param-map.json --envfile=.env --profile=aws-account It’s still an early-stage project, but already helpful in several real-world teams.

    Truthy and Falsy in JS: What Every Developer Should Know
    Stop Guessing: Understand JavaScript Equality the Right Way When you start working with JavaScript, one of the first things you notice is how flexible it feels. You can assign different types of values to the same variable and JavaScript won’t complain. This flexibility is great—but it can also lead to unexpected bugs, especially when you're comparing values or checking if something is "true" or "false." Let’s break down some of these concepts in a beginner-friendly way so you can write safer and more predictable JavaScript code. In JavaScript, you don’t need to declare the type of a variable. For example: let x = 5; // x is a number x = "hello"; // now x is a string x = true; // now x is a boolean This is called loose typing—a variable can hold any type of data, and JavaS…  ( 6 min )

    Amazon Q CLI for Code Review: Focus on What Changed, Not Everything
    This is a submission for the Amazon Q Developer "Quack The Code" Challenge: Crushing the Command Line Some AI-powered coding assistants already support code reviews, but most of them tend to review an entire workspace or just the currently open file. In real-world scenarios though, code reviews are often based on pull requests—where we only need to review changes between two branches, not the whole project. For example, reviewing just the differences between a hotfix branch and main. That got me thinking: wouldn’t it be great if an AI coding assistant could handle that kind of focused review? At least as a first layer—giving us a detailed AI-generated review of the changes before we jump in manually. That way, human reviewers can just focus on refining things further instead of starting from scratch. One of Amazon Q Developer’s cool features is its CLI and MCP (Model Context Protocol) support. So I thought: why not use Amazon Q CLI to compare two branches—say, hotfix and main—and then have it go through the changed files one by one, review them, and finally compile the feedback into a single file using MCP as well? That way, whoever’s reviewing the PR can read the AI’s review first before doing their manual checks. Code Repository Code Review with Amazon Q Developer CLI I used Amazon Q Developer as the first layer of code review—comparing one branch to another, like from hotfix to main. This helps make the review process smoother, more effective, and scalable—especially when combined with a follow-up manual review. What makes it even more exciting is that Amazon Q Developer can both generate code and review it too. Pretty handy, right?  ( 4 min )
    Using Loose Equality in JS/TS
    -- Loose Equality allows different kinds to become an equal kind. I've been feeling, blogposts treat loose equality in JavaScript as a kind of black magic because people do not master it.

I say, make full potential of Javascript's capabilities, intentionally and knowingly. It can save us from some coding overhead, even when the original definition is sometimes flawed.

    Trying to Build in Public — But Reddit Keeps Silencing Me
    So this week, I tried to share what I’m building on Reddit. Two posts. Two different subreddits. Both were removed instantly by Reddit’s filters. No explanation. No mod feedback. Just gone. What were the posts about? I’m building a solo project called KindredCircl — a social platform focused on belonging, privacy, and connection. No ads. No rage-bait. No surveillance. Both posts were written thoughtfully. No spam. No “buy this.” Just honesty, tech stack, and a link to a longer write-up on Dev.to. But apparently, Reddit’s automation saw all that and said: nope. Reddit is supposed to be where indie hackers hang out. Where devs build in public. Where creators share early work and get support. But what I’m realizing is: if your post doesn’t match the format the filter expects, or if you use certain words (like support, link, or solo founder), you might just get silenced. Not because of what you said — but because a bot decided you were promotional by default. I’m still building. I’m still sharing. But I’m reminded how important it is to build spaces where authentic effort isn’t treated like spam. KindredCircl is meant to be one of those spaces. And yes — it still exists, even if Reddit didn’t want to hear about it this week. If you’ve had posts removed without explanation, or felt like you’re shouting into the void, I’d love to hear your story too.

    Audio Steganography, Faster and Friendlier: My Dive into Spectrogram

Wish for "a game," and you might end up with a simple tic-tac-toe when you wanted a fantasy RPG. Ask it to "tell me about dogs," and it could ramble aimlessly about canines. To get useful results, you must phrase your wishes just right. In the world of AI, this art of wording your requests is called prompt engineering. But fear not, brave adventurer – prompt engineering isn't as arcane as it sounds. Think of it as giving instructions to a very smart but overly literal friend. If you're clear and specific, you'll get spectacular results; if you're vague, you might get something hilariously off-base. So, how do we craft the…  ( 6 min )
    🚀 Faster EC2 Launches: Amazon EBS Adds Provisioned Rate for Volume Initialization
    Amazon Web Services (AWS) has just announced a powerful enhancement for Amazon Elastic Block Store (EBS): Provisioned Rate for Volume Initialization is now generally available. This new feature allows you to create fully performant EBS volumes from snapshots with predictable initialization speeds, helping you launch EC2 instances faster at scale. It’s a game-changer for high-performance, time-sensitive workloads. 🧠 The Problem (Before This Feature) When launching EC2 instances from EBS snapshots (like AMIs), volumes are lazy-loaded from Amazon S3. That means data is only fetched when accessed for the first time. This causes: Slower disk I/O initially Inconsistent application performance Delays in workload readiness This has long been a pain point, especially for workloads tha…  ( 4 min )

    Monotone Triangulation. Practical Advice.
    It all started innocently enough. Back in 2009, I just wanted to port Earcut to Flash for a mini-game I was working on. And honestly? It worked — for a while. But over time, I realized that simple solutions tend to fall apart the moment you try to push them to their limits. That’s when I dove into the theory - digging through research papers, YouTube tutorials, and whatever else I could find. One of the most helpful resources was a book by A.V. Skvortsov. Eventually, I landed on the classic approach: decomposing a polygon into monotone pieces. It seemed obvious. And oh - I hit every possible wall while trying to make it work. The first big insight? Replace float with int. That alone got me almost there. But the algorithm was still fragile. Really fragile. Self-intersections, collinear edge…  ( 7 min )
    The only 7 Projects That Makes You Better at Docker
    Docker isn’t just about running containers. It’s about understanding how systems work, why things break, and what to do next. Most tutorials give you commands to copy paste.

    Local PDF Parsing with AWS Textract & Python (Part 1)
    ✍️ Introduction Throughout my experience working with clients from domains like healthcare, insurance, and legal, I often found myself curious about how certain backend document workflows functioned, especially in healthcare. While supporting these systems, I’d often get paged for incidents related to PDF pipelines: upload failures, script errors, or extraction gaps. At that stage, like many in support roles, we’re limited to handling outcomes rather than building or understanding the full solution. Over time, as we gain more experience, build trust, and make people feel confident in our abilities, we gradually get the opportunity to be part of architecture discussions and solution design conversations. But that curiosity about how these pipelines actually work — from PDF upload to raw t…  ( 5 min )

    Why You Should Care About the Agent2Agent (A2A) Protocol as a Developer
    AI agents are no longer science fiction. We're moving fast toward a world where intelligent agents assist in everything from customer service and infrastructure orchestration to dev workflows and automated research. These agents aren’t monoliths—they're modular, specialized, and increasingly autonomous. But there’s a problem: Each one is often trapped in its own framework or API, with no standardized way to talk to others. That lack of interoperability is a major blocker to scaling truly useful, distributed AI systems. That’s where the Agent2Agent Protocol (A2A) steps in—and if you're a developer, now is the time to start paying attention. 🧠 What Is the A2A Protocol?

    Deploying and Exposing Go Apps with Kubernetes Ingress, Part 1
    Kubernetes is the go-to tool for managing containerized apps. While Services expose apps, they lack advanced traffic control. Ingress fills this gap with features like path-based routing, SSL, and load balancing. In this tutorial, we’ll explore Ingress and build a hands-on project using Go, Docker, and Kubernetes. In Kubernetes, Ingress is an API object that manages external access to services, typically for HTTP/HTTPS traffic. It functions as a reverse proxy, load balancer, and traffic router, defining rules to direct requests to different services based on hostnames, paths, or other HTTP parameters. Unlike Kubernetes Services, which expose applications internally or externally using simple port mappings, Ingress offers a more advanced layer for managing web traffic, making it ideal for m…  ( 8 min )

    What Learning to Code Taught Me About Life (That Therapy Didn’t)
    I didn’t expect learning to code to feel like therapy. I remember the first time I started learning how to code. I was 17 years old, wide-eyed and full of curiosity.

    Understanding Constructor Functions
    A constructor function is a special type of function used to create and initialize objects in programming, particularly in object-oriented languages like JavaScript. Think of it as a blueprint or factory for making many similar objects. Imagine you're managing a car manufacturing company. Every car you build shares the same structure—engine, wheels, color, and brand—but each one has its own values. Instead of manually building each car from scratch, you use a car-making machine (constructor function). You input values like color, brand, and engine size, and the machine builds the car for you. function Car(brand, color, engineSize) { this.brand = brand; this.color = color; this.engineSize = engineSize; } This is the constructor function. To create a car: let car1 = new Car("Toyota", …  ( 4 min )

    Rust or Zig: The Battle for the Future of Systems Programming
    In today's rapidly changing programming world, Rust and Zig are the hottest topics. Both modern, low-level programming languages exist mainly to address shortcomings in older systems programming languages like C and C++. But which one would you choose to learn in 2025? Is Zig a competitor to Rust, or does it remain the reigning champion? We will discuss their pros and cons and their best use cases. The Rise of a New Competitor But now, there comes a new competitor: Zig. Lightweight and flexible, it's not going unrecognized by the low-level developers with its focus on manual memory management, compile-time safety, and minimal run-time overhead. With this adoption trend, that question arises among many of how true this is: ''Is Zig a real competitor to Rust?'' Hence, in the following article, we shall compare Rust and Zig, note significant differences, and possibly help you decide on which of the two you are planning to learn in 2025. Why is Rust So Popular? 1. Memory Safety Without a Garbage Collector 2. Fearless Concurrency 3. Performance on a Par With C and C++ Rust provides zero-cost abstractions that allow a high level of expressiveness in writing programs while incurring little or no run-time overhead. In many cases, Rust is as fast as or faster than C/C++. 4. A Thriving Ecosystem and Strong Tooling Rust Uses and Applications For massively scalable applications, Rust fits the bill. The flip side of such scalability would certainly be a lot of complexity, and this is where Zig fills the void. The Minimalist Challenger: Zig Unlike Rust's expensive and stringent powers with sections for systems programming, Zig is strictly minimalist and performance-optimized with no specific automated memory management.

    Two Worlds, One Goal: Creating Balance.
    Now this... this is where the real battle began. On one side, Blockchain Development — a world of code, decentralization, and smart contracts. Forex Trading — candles, charts, patterns, and pips. So where do I go from here? At first, it was chaos. I’d be deep in writing a smart contract in Solidity, then moments later, I’d find myself back on TradingView, analyzing XAU/USD like my life depended on it. My mind was constantly bouncing between gas fees and candlesticks. I knew something had to give — this back-and-forth was draining my focus, and if I kept going like that, I’d end up mastering neither. So I paused. “How do I fix this?” After some much-needed clarity, I narrowed it down to three options: Quit trading and go all-in on tech. Quit tech and go all-in on trading.

    Question: Design changes in my Next.js + Tailwind app do not reflect in production (Vercel)
    I’m building a project using Next.js (latest version) with Tailwind CSS and deploying it to Vercel. The issue is: all design changes (layout structure, visual style updates, etc.) show up perfectly in local development, but they don’t appear at all on the production URL after deployment. Things I’ve tried: git push to main runs without errors. Vercel deployment shows status as “Ready” with no build errors. Forced browser refresh (Ctrl+Shift+R), cleared cache, used incognito mode. Tested on multiple browsers and devices. What could prevent design changes from being reflected in production? I’d appreciate any advice or suggestions. I’ve repeated the steps multiple times and still can’t get the updated design to show live.  ( 3 min )

    Cloud Service Types: IaaS, PaaS, SaaS
    Cloud computing isn't simply a catchphrase in today's digitally first society; it's the foundation of contemporary company operations. The cloud makes speed, size, and cost-effectiveness possible for everyone from start-ups releasing mobile apps to multinational corporations overseeing operations worldwide. However, "the cloud" isn't a universally applicable answer. Different kinds of cloud services are available, depending on what you're building and how much control you desire. Let's dissect them. 1. Infrastructure as a Service (IaaS) What User Manages: What the Provider Manages: Use Cases: Examples: Ideal for: Developers and system administrators who want flexibility without managing hardware. 2. Platform as a Service (PaaS): What User Manages: What the Provider Manages: Use Cases: Examples: Ideal for: Developers who want to build applications quickly without worrying about backend setup. 3. Software as a Service(SaaS): What User manages: What the Provider Manages: Use Cases: Examples: Ideal for: End-users or businesses who want to use powerful software without installing or maintaining it. What Should You Pick? Choose Infrastructure as a Service (IaaS) if you require total control over your environment. Select PaaS if you wish to concentrate just on development. SaaS is your friend if all you need to do is use an app to get started quickly.  ( 4 min )

    Why is the URL parameter None in FastAPI from Next.js?
    Understanding the Issue of Missing URL Parameter in FastAPI When using a Next.js frontend to send data to a FastAPI backend, it's important to ensure that all parameters, including files and URLs, are properly formatted and sent in the FormData. In your case, while the username and files are being received correctly by the FastAPI endpoint, the urls parameter is showing up as None, which can be quite perplexing. Let’s dive into the potential reasons why this is happening and how to resolve it. Reasons Why the URLs Parameter Might be None Incorrect FormData Structure: One common reason for receiving None in the FastAPI backend for the urls parameter could be due to the way the data is appended to the FormData in the Next.js code.

    Building Legal AI Tools: Challenges Developers Need to Know Before Writing a Single Line of Code
    Legal tech is booming, but building for the legal industry comes with hidden technical, ethical, and compliance challenges..here’s what every dev should understand before jumping in. So you want to build the next AI tool that revolutionizes law? Great!!legal professionals need better, faster tools. But before you start coding your first legal document parser or compliance bot, there are real-world landmines to avoid. Legal data is often highly sensitive and subject to strict confidentiality rules (think attorney–client privilege or court-sealed documents). Scraping, storing, or even training on this kind of data without safeguards could expose you and your users to legal risk. Also, when your AI outputs a compliance decision (e.g., GDPR audit findings or AML flags), you're not just providing a "suggestion", you may be influencing legal liability. Many jurisdictions require explainability, auditability, and even human-in-the-loop systems. Legal language is dense, full of nuance, and jurisdiction-dependent. Two identical phrases may have opposite meanings depending on where and how they appear. Of course, you know there are already APIs and frameworks built for legal applications. Don’t reinvent the wheel. Legal professionals are risk-averse by design. They value clarity, documentation, and accuracy over speed. Your app’s UX must reflect that. If they can’t trust it, they won’t use it, no matter how smart it is. Are you building legal tech tools? What challenges have you run into? Drop a comment or connect—let’s push the future of legal AI forward, together.  ( 3 min )

    uniapp开发HarmonyOS NEXT应用之项目结构详细解读
    昨天的文章介绍了使用uniapp跨平台鸿蒙应用时如何配置开发环境和运行调试项目,今天介绍一下uniapp项目目录的结构。 上面的两个文件夹pages中存放的是项目的页面,static则是存放静态资源的文件。 继续往下面看,App.vue文件打开可以看到它里面存放了项目的生命周期函数,比如项目启动、项目退出等等。 index.html相当于项目的根页面,它虽然也属于页面,但是在uniapp中通常是不需要大家修改的,因为可以看到里面有一个id是app的容器,我们在项目中写的所有代码最终都会注入到这个容器中。 Main.js是整个项目的核心入口文件,负责初始化Vue实例和全局配置 Manifest.json中存放了项目的各种配置文件,项目的名称、版本、描述、各个平台的的运行配置都在这里。 Pages.json中存放了项目中所有的页面路径和全局样式,尝试在globalStyle中的样式做一些修改,项目的全局样式就会被改变。而当新建了一个页面时,也会在这里自动注册。 最后的uni.scss文件,打开可以看到它已经给出了解释,这里是uni-app内置的常用样式变量。 以上就是uniapp项目初始化后的项目结构,还没结束,当我们运行项目后,还会新增unpackage目录,打开可以看一下是不是很熟悉,编译器把uniapp项目编译成了鸿蒙项目,这就是跨平台开发的运行原理。 以上就是对uniapp项目结构的详细解读。经历了两天的项目环境搭建和介绍,接下来的教程我们会进入到正式的跨平台开发编码环节,欢迎您持续关注。  ( 2 min )

    Project made with latest Angular 19 features
    I've embarked on a project that, although simple, has been a challenge. I've built my personal website, resume, and code visible on GitHub. This has been a bit of a challenge, because I knew my code would be visible and analyzed by recruiters. Still, I did it with love and enjoyed the experience. With it, I've had to be a software architect, content creator, project manager, developer, and SEO. Along the way, I've learned and grown. I've seen things I want to take to other projects, and the importance of following the principles of clean code, design patterns, and an architecture that's easy to scale. This project is built with Angular version 19. I use standalone components, computed properties, and effects, as well as rxResource and new features of the framework. For the UI, I used Angular Material, but minimally. The design is simple, designed so that people with visual impairments can use it without problems, balancing color contrast and good visual results. The result is my personal website, which I've been building little by little, and which I'm now sharing with you at www.antonioubedamontero.com. I'm making small improvements, adding features, and polishing what will become my brand image. With enthusiasm and love, like when you're working on a project you feel comfortable with. angular #web-dev #frontend  ( 3 min )

    Exploring Compile-Time Programming in Zig: Practical Examples and Use Cases
    One of Zig’s most powerful features is its ability to run code at compile time. This enables code generation, validation, and optimizations that would be much harder (or impossible) in many other languages. In this tutorial, we’ll walk through practical examples of Zig's compile-time programming and how you can use it effectively. You can run code at compile time using comptime: const std = @import("std"); const num = comptime calculate(); fn calculate() usize { std.debug.print("Evaluating at compile time\n", .{}); return 42; } Here, calculate() is run at compile time, and num becomes a constant value. comptime Parameters Zig lets you write generic functions and types using comptime parameters: fn identity(comptime T: type, value: T) T { return value; } const result = ide…  ( 4 min )

Every Zig project with multiple files or custom build steps uses a build.zig script. This script defines how to build your application using Zig's std.Build API. build.zig Example Here’s a simple build script for a Zig executable: const std = @import("std"); pub fn build(b: *std.Build) void { const target = b.standardTargetOptions(.{}); const mode = b.standardReleaseOptions(); const exe = b.addExecutable(.{ .name = "hello", .root_source_file = .{ .path = "src/main.zig" }, …  ( 4 min )
    How to Store Data in a Dart Class Using Maps Correctly?
    Introduction If you're new to Dart and want to manage data efficiently, using a class to store instances in a map is a great approach. In your case, you're trying to maintain a persistent map that holds instances of myCar, but you're encountering an issue where the map is reset every time addInfoToMap() is called. Let's explore why this is happening and how to fix it. Why is myMapOfCars Being Reinitialized? The main reason myMapOfCars is reinitialized each time is that it's defined as an instance variable (implicitly associated with each instance of the myCar class) rather than as a static variable that belongs to the class itself. Each time you create a new instance of myCar, a new myMapOfCars is created, which is why it appears empty when you call addInfoToMap(). Solution to Persist Data…  ( 4 min )

    A Beginner's Guide to Enums and Error Sets in Zig
    Enums and error sets in Zig offer powerful ways to model states and failures with clarity and precision. In this tutorial, we’ll cover the basics, then walk through real-world uses of both types — and how they play nicely together. Enums let you define a type with named values: const Direction = enum { North, South, East, West, }; You use them like this: const dir = Direction.North; Zig will guarantee at compile time that dir is one of the defined directions. Zig encourages exhaustive switching — the compiler checks for missing cases: switch (dir) { Direction.North => std.debug.print("Going up\n", .{}), Direction.South => std.debug.print("Going down\n", .{}), Direction.East => std.debug.print("Going right\n", .{}), Direction.West => std.debug.p…  ( 4 min )

    Low-Latency Mental Math: Quick Additions and Subtractions for Software Developers
    In a world overflowing with digital tools, it’s easy to dismiss mental math as outdated — a quaint relic from the pre-calculator age. But there’s something uniquely powerful about sharpening your ability to think numerically without external support. Like optimizing code for runtime efficiency, refining your mental math streamlines your internal thought processes and reduces your cognitive load. This article is based on a short guide I wrote called Adding and Subtracting Fast - Essential Tactics to Speed Up Mental Calculations with Whole Numbers, the first in a three-part series I began in 2018.

    How to Fix Image Loading Issues in Flutter with YouTube Thumbnails?
    Introduction When working with Flutter, developers often face challenges while integrating external resources, such as images from different domains. A common issue arises when trying to load YouTube video thumbnails, leading to errors that may hinder the application's functionality. If you are using the youtube_plyr_iframe package in your Flutter project and encountering problems fetching YouTube thumbnails using Image.network, you are not alone!

    💍 aws-vault-lite: One AWS Secret to Rule Them All
    This is a submission for the Amazon Q Developer "Quack The Code" Challenge: Exploring the Possibilities At my company, we still don’t have a proper tool to manage secrets. So, naturally, people come up with their own solutions—some of them not very secure. I had the idea of using AWS Secrets Manager as a secure place to store our secrets. But there was a challenge: Then I discovered that a single AWS Secret can store up to 64KB, which is more than enough for a bunch of simple strings. That got me thinking... So I did it! :) Introducing aws-vault-lite — a lightweight secret manager I built in just one night (with a hand from Amazon Q). What is? That was a pretty polite intro, wasn’t it?

    Text Adventures in the Age of AI

The DnD games I played with friends had a step-up on this, of course: a human being who could intelligently respond to anything you tried. It was only a matter of time before somebody had the idea to use AI for adventure games, and there are some interesting options out there I'm keen to try sometime: AI Dungeon, DREAMIO and Friends & Fables. Inworld Origins looks like it will take it even further and provides a cinematic experience where you talk to suspects at a crime scene, and they respond intelligently to anything you ask.

    El Salvador stacks 7 Bitcoin in last week, despite IMF deal
    The government of El Salvador continues stacking Bitcoin (BTC) for its national crypto reserve, despite an ongoing deal with the International Monetary Fund (IMF) stipulating that the Central American country stop using public funds to purchase Bitcoin as one of the conditions for a loan agreement. According to data from the El Salvador Bitcoin Office, the country acquired an additional seven BTC in the last seven days, bringing its total holdings to 6,173 BTC, valued at over $637 million. El Salvador's Bitcoin Office has continued its steady pace of Bitcoin acquisitions months after the IMF agreement was signed and shows no sign of halting its Bitcoin purchases. The Central American country is one of the only nations actively purchasing Bitcoin in open market operations, and its national …
    Bitcoin SV investors attempt to resurrect 2019 Binance lawsuit
    Investors of Bitcoin Satoshi's Vision (BSV) — a hard fork of Bitcoin Cash (BCH), which itself is a hard fork of the Bitcoin (BTC) protocol, are attempting to revive a 2019 lawsuit against crypto exchange Binance for delisting the altcoin, which the litigants claim stunted the price of BSV.   According to Law360, attorneys for the plaintiffs argued that a July 2024 decision from the UK Competition Appeal Tribunal dismissing the "loss of chance" claim made against Binance for delisting the token, should be reconsidered. The litigants demanded $9 billion in damages, in the original case. The investors continue to claim that Binance's 2019 delisting of BSV and similar major exchange delistings are the primary drivers of BSV's long-term price decline and its failure to attract the investor atte…
    Bitcoin now deflationary due to Strategy's BTC purchases — Analyst
    Strategy, a Bitcoin (BTC) treasury company, is accumulating Bitcoin at a faster rate than total miner output, giving the supply-capped asset a -2.33% annual deflation rate, according to CryptoQuant CEO and market analyst Ki Young Ju. "Their 555,000 BTC is illiquid with no plans to sell," the analyst wrote in a May 10 X post. "Strategy's holdings alone mean a -2.23% annual deflation rate — likely higher with other stable institutional holders," Ju continued. Michael Saylor, the co-founder of Strategy, is an outspoken Bitcoin advocate who evangelizes the scarce digital currency to potential investors and has inspired many other companies to adopt a Bitcoin treasury plan.

    In volatile markets, RWAs like gold are a lifeline
    Opinion by: Kevin Rusher, founder of RAAC It’s a volatile world out there. This year, we’ve seen stocks take a wild ride as gold has pumped and crypto has been caught somewhere in the middle. Investors have dumped risk assets and scrambled for safe havens. Gold is leading the charge. While gold is safe, it is not very hard-working. Unlike cash and treasuries, the yellow metal does not generate income. Now, more than ever, investors need to be able to earn yield on gold — particularly in the decentralized finance (DeFi) sector. The only way to make money from gold is to buy low and sell high. Most investors don’t tend to buy gold like this. That’s for good reason — over the long term, gold’s performance is typically consistent, if not without a few peaks and troughs here and there, as we h…
    Why is Ethereum (ETH) price up today?
    Key takeaways: Ether is set for its best weekly gain since May 2021. Ethereum’s Pectra upgrade, mega-whale accumulation, and a major short squeeze fuel the rally. Technical patterns suggest a potential 40% rally toward $3,400 as ETH bounces off key support. Ether (ETH) is on course to record its best weekly performance since May 2021, having risen by over 37.50% in the week ending May 11, including 10.30% gains in the last 24 hours. US tariff updates, Pectra upgrade boost Ethereum The announcement of a new trade agreement between the US and the UK on May 8 and the initiation of US-China trade talks afterward have bolstered upside sentiment in Ether and the broader crypto market. Additionally, Ether benefits from its Pectra upgrade on May 7, which introduced key improvements like higher…
    4chan rises from the dead: How the imageboard moves crypto markets
    After 4chan was hacked on April 14 and vast troves of user and moderator data were leaked online, the controversial website quickly went down, and many believed it would never recover. However, less than two weeks later, the imageboard was back online, defiant as ever. “4chan is back,” an official blog post proclaimed. “No other website can replace it, or this community. No matter how hard it is, we are not giving up.” The imageboard has left its mark on the world in many consequential ways, birthing countless memes and conspiracy theories, serving as a platform for political movements ranging from the alt-right to Anonymous, and acting as a dumping ground for leaks and hacks of all sorts.  Crypto is no exception, with 4chan also a historically influential gathering place to share altcoin …
    UK to become ‘safe harbor’ for crypto with new draft rules — Experts
    On April 29, UK Finance Minister Rachel Reeves unveiled plans for a “comprehensive regulatory regime” aimed at making the country a global leader in digital assets. Under the proposed rules, crypto exchanges, dealers, and agents will be regulated similarly to traditional financial firms, with requirements for transparency, consumer protection, and operational resilience, the UK Treasury said in a statement released following Reeves’ remarks. Per the statement, the Financial Services and Markets Act 2000 (Cryptoassets) Order 2025 introduces six new regulated activities, including crypto trading, custody, and staking. Rather than opting for a light-touch regime similar to the EU’s Markets in Crypto-Assets (MiCA), the UK is applying the full weight of securities regulation to crypto, accordin…
    RedotPay enters South Korea with crypto-powered payment cards
    Hong Kong-based fintech firm RedotPay has reportedly launched its cryptocurrency-enabled payment cards in South Korea, positioning itself as a potential disruptor in a market dominated by traditional credit card firms and mobile payment services. The company’s crypto debit cards—both physical and virtual—are now accepted at all Korean merchants that support Visa, according to a May 9 report by The Korea Economic Daily. The move marks RedotPay’s latest step in global expansion, following its earlier partnership with Visa and BIN sponsor StraitsX in February 2025 to enhance cross-border crypto payment capabilities. RedotPay, founded in 2023, has rapidly scaled since the soft launch of its crypto card program in late 2024. It now serves more than 4 million users worldwide. In South Korea, use…
    Robert Kiyosaki says ditch ‘fake money’ for Bitcoin, gold, and silver
    Robert Kiyosaki, businessman and best-selling author of Rich Dad Poor Dad, is once again sounding the alarm on the dangers of centralized monetary policy — urging his followers to abandon what he calls “fake money” and adopt alternatives like Bitcoin, gold, and silver. In a May 10 post on X, Kiyosaki backed a hardline stance against central banking systems, particularly the Federal Reserve, while quoting former US Congressman Ron Paul. Ron Paul, a longtime critic of the Fed and author of End the Fed, described interest rate setting by central banks as “price fixing,” equating it to socialist and Marxist economic control. Paul warned that such mechanisms erode personal wealth and undermine economic freedom — a sentiment that aligns closely with Kiyosaki’s long-held concerns. “Fake money lea…
    BlackRock’s Bitcoin ETF posts $356M inflows, longest inflow streak in 2025
    BlackRock’s spot Bitcoin ETF (IBIT) capped off the trading week with another day of inflows, pulling in $356.2 million on May 9. The fund has now extended its inflow streak to 19 consecutive days — its longest run of inflows so far this year. IBIT’s inflow streak has been ongoing since April 14, and has coincided with a volatile Bitcoin (BTC) market, with the asset trading between $83,152 and $103,000 over the period. However, market sentiment has been increasing after the asset reclaimed and held above the $90,000 price on April 23 before reclaiming the $100,000 price on May 8 for the first time since Feb. 1.

    Bitcoin won’t see ‘gigantic’ SWF buying until laws greenlit — Scaramucci
    Sovereign Wealth Funds are already gaining exposure to Bitcoin, but significant allocations won’t happen until the United States establishes clearer regulations for the digital assets industry, says SkyBridge founder Anthony Scaramucci. “I think they are buying it, I think they are buying it on the margin,” Scaramucci, former White House director of communications during US President Donald Trump’s first term, said on Anthony Pompliano’s podcast on May 8. Legislation will lead to “large blocks of buying” “I don’t think it is going to be a gigantic groundswell of buying until we greenlight legislation in the United States,” he added. Scaramucci previously said in a February interview with the Financial Times that he expects the US government to propose crypto legislation in November. SWFs a…
    Bitcoin yet to hit $150K because outsiders are ghosting — Michael Saylor
    Strategy founder Michael Saylor says Bitcoin hasn’t reached $150,000 yet because holders without a long-term outlook have been selling off while a new cohort of investors are beginning to enter the market. “I think we’re going through a rotation right now,” Saylor said on the Coin Stories podcast with Natalie Brunell on May 9. The lack of “10-year investor mindset” led to Bitcoin sell-off Saylor said “lots of non-economically interested parties are rotating out of the asset.” However, at the same time, “a new cohort of investors are entering.” “A lot of Bitcoin, for whatever reason, was left in the hands of the governments and the hands of lawyers, and in the hands of bankruptcy trustees,” he added. Strategy’s Michael Saylor spoke to Natalie Brunell on the Coin Stories podcast. Source: Na…
    Ethereum price greenlit for further upside after surprise 29% ETH rally
    Key takeaways: ETH price rallied by 22% on May 8, but demand for spot ETH ETFs and derivatives remains muted.  President Trump’s reversal on certain altcoins aligns with ETH’s renewed outlook.  Ether (ETH) posted an impressive 29% gain between May 8 and May 9, likely marking the end of a 10-week bear market that bottomed out at $1,385 on April 9. This sharp move triggered the liquidation of over $400 million in short (sell) ETH futures positions, suggesting that whales and market makers were caught off guard. Despite the surge, traders have maintained a neutral stance in ETH derivatives. Whether this apparent lack of conviction reflects a genuine trend reversal or merely precedes another test of the $2,000 level remains to be seen. Ether 3-month futures annualized premium.

    A spread argument must either have a tuple type or be passed to a rest parameter. ts(2556)
    You want to pass variable args to a function, like so: const doSomething = (a: string, b?: string, c?: string): void => {}; However, TS didn't like it... // não bom const args = [['a', 'b', 'c'], ['a', 'b'], ['a']]; args.forEach((arg) => { // A spread argument must either // have a tuple type or be passed // to a rest parameter. ts(2556) vvvvvv doSomething(...arg); }) The problem is that doSomething expects one to three arguments of type string, but arg is typed as string[]. We need to narrow the type down, to match the arguments of doSomething() // bom const properTypedArgs: [a: string, b?: string, c?: string][] = [['a', 'b', 'c'], ['a', 'b'], ['a']]; properTypedArgs.forEach((arg) => { doSomething(...arg); }) This works, but if you don't fancy re-typing the function's argument type defs or don't have it handy, TS utility type got you covered: // ainda melhor const properTypedArgs: Parameters[] = [['a', 'b', 'c'], ['a', 'b'], ['a']]; properTypedArgs.forEach((arg) => { doSomething(...arg); }) That's all!

    Debugging Browser Extensions: Taming the Chaos Like a Pro 🛠️
    Hey fellow developer! 👋 Let’s talk about the real journey of building browser extensions: You spend hours crafting the perfect feature, hit "Load Unpacked," and… nothing happens. Or worse—your extension works on your machine but turns into a pumpkin 🎃 on your friend’s browser. Debugging extensions can feel like wrestling gremlins, but don’t panic! I’ve been there (and lived to tell the tale). Let’s break down the most common errors and their fixes so you can get back to shipping magic. 1. “My Extension Doesn’t Load!” (Manifest File Mayhem) The Error: Chrome/Firefox ignores your extension, or you get a cryptic “Invalid manifest” warning. Why It Happens: Manifest Version Mismatch: Using V2 syntax in a V3 world (or vice versa). Missing Fields: Forgot action, permissions, or hos…  ( 4 min )
    Modern Browser Extension Development: Supercharge Your Workflow with React, Vue, or Svelte
    Hey fellow devs! 👋 Let’s talk about browser extensions.

    Coding Challenge Practice - Question 5
    Today's question Create a React application that allows users to create, display and delete blog posts. Solution The first step is to evaluate the boilerplate provided. There are 3 boilerplate files: Home.js import React from "react"; import Input from "./Input"; import PostDisplay from "./PostDisplay"; function Home() { return ( {"Title"} {"Description"} Delete ); } export default PostDisplay; The Home component(file) is provided as the parent component, which manages the state of the application. So, variable states for all blog posts, and a single new blog post will be created. The input component is responsible for creating new blog posts, therefore, the variable states for new blogs will be passed into it after it has been created in the Home component. Then, the PostDisplay component, which handles showing all blog posts, will have the state for all blog posts passed into it.  ( 3 min )

    How the Childfree Demographic Is Impacting the Real Estate Market
    The childfree demographic, consisting of individuals or couples who choose not to have children, is increasingly shaping trends in the real estate market. As this demographic grows, their preferences for housing are influencing various aspects of the housing market, including demand for specific property types, locations, and community features. With different lifestyle priorities, including mobility, urban living, and less space, the childfree population has started to play a more significant role in how developers, investors, and real estate agents approach their offerings. While the childfree group may share some housing preferences with other demographics, their choices reflect a unique set of needs that is gradually gaining attention from the real estate industry.

    How to Fix Colorization Issues in Dart's Pathfinding App?
    Introduction Are you currently tackling a pathfinding visualizer app using Dart and Flutter? If you're feeling overwhelmed by the programming challenges and specifically by your container colorization logic, you're not alone! In this article, we will go through how to successfully manage color changes for your start and end containers without affecting all elements on the grid. Understanding the Problem In your Flutter application, the objective is to select a 'start' and 'end' container when clicking on the grid, and change their colors accordingly. However, when you try to set the 'start' container color to green, it’s inadvertently updating every container to green, which is not the intended behavior. This issue typically occurs due to how the state and rendering logic is structured in …  ( 4 min )

    Finding (and recovering) your Amazon Q Developer prompt history
    Wanted to share a very quick on something I learned that was pretty useful to me, so thought it might be useful to others. Here is a scenario that some of you might be familiar with: You have a successful Amazon Q Developer session, and then maybe a few days later, you are trying to recall exactly what you did and how you put your prompts together - what can you do? As it turns out, a recent update to Amazon Q Developer was a big help. In the Amazon Q Developer chat interface, there is a new icon next to the different tabs (its an icon of a click, which when you hover over says "View Chat History") which when you click on this, it will bring back a list of previous chats that have been recorded. What does this mean? In the "~/.aws/amazonq/" directory there is a "history" directory, and looking at it, it contains a number of time/date stamped json files. ├── history │   ├── chat-history-0f97086b54fd7d6128dfd80426dfd63d.json │   ├── chat-history-10d817f64fc99f04badf1568a6c23814.json │   ├── chat-history-deba93a681a17ae26ff2b977acf0ba97.json │   ├── chat-history-fa5091a7425e7938fe770a584b63076e.json │   └── chat-history-no-workspace.json These are what the Amazon Q Developer VSCode plugin now produces as you start using it. That said, because I had deleted my project, and so I was unable to get this from VSCode itself. Aarrgh, I thought to myself. Not to worry though. I still had the files in the history directory. So reviewing these with my favourite json viewer (I knew which file to use, aligning date stamps from these and the code files in my project workspace), allowed me to extract all the history, including prompts and responses. Very handy to know if you want to go back in time. This saved me, so hoping it will help others who are looking to recover what they did.  ( 3 min )

    Abhishek Desikan | Growing as a Software Engineer Means Letting Go of Perfection
    When I started writing code, I thought the goal was perfection. A flawless feature. A zero-bug release. The cleanest, DRYest, most elegant solution to every problem. But if there’s one thing software engineering teaches you—again and again—it’s this: Perfect doesn’t ship. Progress does. Behind every product you love, every app you use daily, and every "it-just-works" moment, there’s a messy history of trade-offs, iterations, rewrites, and late-night breakthroughs. There’s never been a perfect version—only the best version for right now. “If you’re aiming for perfection, you’ll never release,” he says. “But if you aim for learning, you’ll improve with every commit.” That’s the shift that happens when you grow—not just as a coder, but as an engineer. Early Career: Learning the Rules Most engineers begin their journey by learning the rules. Mid-Career: Building Beyond Code As you gain experience, your job evolves. You're not just writing functions—you’re: The Myth of Mastery There’s a moment many engineers hit mid-career: you expect to feel confident, but instead, you feel behind. Late Career: Scaling Impact By the time you’re a senior or staff engineer, the problems you solve are rarely just technical. Letting Go to Grow So what does it really mean to grow as a software engineer? Final Thoughts: We’re All Still Learning No matter where you are in your career—just starting out, mid-level and unsure, or senior and scaling—remember this: You don’t have to be perfect. You just have to keep learning. Great software is built by people who care enough to try, fail, ask, share, and try again. People like Abhishek Desikan, who show that engineering is not just about building products—it’s about building people, teams, and ethical systems that serve others well. “We’re not just writing code,” Desikan reminds us. “We’re writing the story of how people experience technology.” And when we do that with care—even if it’s not perfect—we’re already doing something right.  ( 5 min )
    How to Ensure Parallel Task Execution on iOS 15 Using Swift?
    Introduction When developing high-performance applications, managing concurrency efficiently is crucial. In this article, we will address how to ensure that multiple tasks run in parallel on iOS 15 while using Swift's async/await and TaskGroup.

    Building a Book Sharing application with Amazon Q CLI
    I read a lot, and always have a couple of books on the go at any one time (currently Linchpin by Seth Godin and The Prisoner of Heaven by Carlos Ruiz Zafon. I am always on the lookout for a new book though, and this thread on LinkedIn sparked an idea (check the comments) about building a simple book sharing application that a group of friends might use to share good books they recommend. I had an idea of what I wanted to create: a simple web application that a group of friends could use to create lists of the books they are reading, provide ratings and comments, and then allow them to share and borrow books they might be interested in. I had a couple of hours whilst I was travelling, and wanted to use Amazon Q CLI to build this. Why? I have been slowly switching from VSCode to Zed, and the…  ( 10 min )
    The Runway Walk: Techniques for High-Fashion and Commercial Modeling
    The art of runway walking represents far more than simply moving from point A to point B—it’s a carefully honed skill that conveys brand aesthetic, garment movement, and professional polish. While television and social media often portray modeling as effortless, the reality involves precise technique, body awareness, and adaptability to different show requirements. The walk serves as a model’s primary tool for bringing clothing to life, requiring equal parts discipline and artistry to execute effectively. Proper runway technique begins with posture that appears relaxed yet controlled. The ideal stance starts with shoulders pulled back and down, creating an open chest without appearing stiff. The spine maintains natural alignment from the tailbone through the neck, allowing for fluid moveme…  ( 5 min )
    How to Fix Client ID Assignment Issues in ASP.NET with SQLite

    Conquer the Subarray Sum: Sliding Window vs. Brute Force
    Hello everyone! Ever wrestled with finding the smallest contiguous subarray within an array that sums up to a given target? It's a classic problem, and today we'll explore two contrasting approaches in JavaScript: the elegant sliding window and the straightforward brute force. Let's dive in! Given an array of positive integers nums and a target integer target, our mission is to find the smallest contiguous subarray whose elements sum up to be greater than or equal to the target. If no such subarray exists, we return 0 (or some other indicator). The most intuitive approach is to consider all possible subarrays. We can achieve this using nested loops: The outer loop iterates through all possible starting indices i from 0 to n-1 (where n is the length of the array). The inner loop iterates …  ( 4 min )

    Lessons from Building a Full Invoice App for the Price of a Netflix Subscription
    Like a lot of devs, I built a side project that scratched a personal itch: an invoice generator. But instead of going full SaaS startup mode, I treated it as a challenge—build something clean, useful, and fast, with a real login system, server-side PDF generation, and as little overhead as possible. The result is InvoiceDen, a React-based web app hosted on Cloudflare Pages, with backend functionality on an EC2 instance, all for about $8/month. Here’s what I learned architecting it on a shoestring budget — and how you can do something similar without spinning up Kubernetes or draining your wallet. The app is split into a classic frontend + backend setup, but optimized for cost and simplicity.

    The Real Reason Cloud Costs Spike After Deployment (And How to Stop It)
    It’s a common story: a team launches their application to the cloud, celebrates the deployment and then, weeks later, is shocked by a ballooning cloud bill. What started as a low-cost, high-efficiency architecture suddenly feels bloated and unpredictable. The truth is, most cloud cost spikes don’t come from initial deployments, they come from what happens after. And if you don’t have visibility or automation in place, it’s easy to lose control. Here’s what’s really driving those post-deployment cloud cost spikes and what you can do to stop them with the help of Kuberns. Idle resources that never got turned off After deployment, environments like staging, dev, or feature branches are often left running. Temporary services that were only meant for testing remain active, silently consuming…  ( 4 min )

    WordPress Won't Save Your SEO
    I recently tried out 5 CMS platforms to use for our blog on sliplane.io and wrote a short section about why I did not like WordPress. Mainly that it’s bloated and plugin-heavy. Some people immediately started firing at me, telling me SEO would be "whack" if I used anything else... as if SEO was a feature toggle in WordPress. But let’s be clear about something: Google doesn’t rank your site based on your CMS! Google doesn’t care if you’re using WordPress, Webflow, Drupal or your content is served from a Google Sheet. Google doesn’t have a CMS bias built in. It doesn’t know how "clean" your CMS feels or cares about how many Yoast plugins you’ve installed. It only sees data. Numbers. Metrics. That's it.

    5 Reasons Why Some Junior Developers Never Become Seniors
    Becoming a senior developer isn’t just about years of experience—it's about how you grow, think, and adapt. Unfortunately, not every junior developer makes it to the senior level. In this post, I’ll break down five common reasons why that growth sometimes stalls. You risk becoming outdated if you’re not actively learning new frameworks, languages, or patterns. Reading documentation, experimenting with side projects, and staying curious are essential habits. Seniors don’t stop learning—they learn faster and more strategically. Tip: Allocate a few hours each week to explore something new, even if it's outside your current stack. It’s one thing to write code that works—it’s another to understand why it works and how it can be improved. Junior developers who always reach for Stack Overflow bef…  ( 4 min )
    The Ultimate AI Experiment: When LLMs Play the Danganronpa Killing Game (Part 2)
    In Part 1, we talked about why we threw AIs into the wild world of Danganronpa – we wanted AI game characters that are actually interesting!

    Dockerize mutliple containers with compose
    Use case - what it solves So If you're familiar with docker containers so far (if not, read my previous two articles on this), When there's more than 1 container, and they have to interact, there's some things you have to repeat, like: pulling image & creating a container. allocate volumes, pass ENV args, etc to container have all containers running in same network . Now if there's 3,4,5,.. or more, it gets more hectic, see where this is going? Docker compose solves that, by "composing" up your containers config in a file type called "yaml" (its similar to json - a data format, usually for configs). You still have things like Dockerfile and concepts of containers are the same, its just the process that's simpler. A quick example of 3 containers rolling up using docker compose.

    JavaScript Closures in Action: Solving Fibonacci with Memoization
    If you're learning JavaScript, you've likely come across closures — a concept that's easy to overlook but incredibly powerful. In this post, I'll break down closures using a real-world coding example: computing Fibonacci numbers with memoization. A closure is when a function remembers the variables from its lexical scope, even after the outer function has finished executing. In other words, inner functions can "close over" variables defined in an outer function — keeping them alive between calls. Let’s start with a simple (but inefficient) recursive Fibonacci implementation: function fib(n) { if (n <= 1) return n; return fib(n - 1) + fib(n - 2); } console.log(fib(10)); // 55 This works, but it's horribly inefficient for large n due to repeated calculations. Let’s use a closure to store previously computed Fibonacci numbers (aka memoization) and avoid redundant work. function createFibonacci() { const memo = {}; function fib(n) { if (n in memo) { return memo[n]; // Return cached result } if (n <= 1) { memo[n] = n; } else { memo[n] = fib(n - 1) + fib(n - 2); } return memo[n]; } return fib; } const fibonacci = createFibonacci(); console.log(fibonacci(10)); // 55 console.log(fibonacci(50)); // 12586269025 — much faster due to caching! memo is defined once inside createFibonacci() and persists across calls to fib() because of closure. Even after createFibonacci() has returned, the fib() function still remembers the memo object. This is the closure in action: the inner function keeps access to its outer scope. Closures allow us to: Preserve state across function calls without polluting the global scope. Create factory functions like createFibonacci() that generate self-contained logic. Enable powerful patterns like memoization, function factories, and data encapsulation. Closures aren't just theoretical — they’re a practical tool for writing clean, efficient JavaScript. Have any cool uses of closures? Drop them in the comments!  ( 3 min )

    Beyond `omitempty`: Understanding `omitzero` in Go 1.24
    In Go version 1.24, the encoding/json package introduced the omitzero tag, making the behavior of ignoring zero-value fields more explicit and customizable. This article provides a detailed explanation of how to use the omitzero tag. omitzero Tag The omitzero tag is used to control which zero-value fields should be omitted when serializing Go objects into JSON. Unlike the omitempty tag, which omits empty-value fields, zero values and empty values, while similar, are not equivalent in Go. For example: For the time.Time type, the zero value is "0001-01-01T00:00:00Z", which is not considered an empty value. For a slice field like IntSlice []int, both [] and nil are considered empty values. omitzero Precise control: Explicitly omits zero-value fields, rather than empty-value fields. Cust…  ( 4 min )

    From Setup Hell to Dev Heaven: Why You Should Use Dotfiles

    Web Cache Deception Attacks
    Web Cache Deception is a vulnerability first described in 2017. It occurs when a caching system — such as a reverse proxy or CDN — can be tricked into caching sensitive, dynamic content that should only be delivered to authenticated users but ends up being publicly available. This is usually due to poorly thought-out or inconsistent configurations in how the cache interprets and stores different types of requests. Many caching systems have simple rules for deciding what can and cannot be cached. A common pattern is to only cache "static" files — such as those ending in .js, .css, .png, .ico, etc. The problem arises when the cache relies solely on the structure of the URL path to make this decision, ignoring the actual behavior of the server behind it. Imagine this: the caching system is in…  ( 4 min )

    Sharding vs. Partitioning
    If you're building anything beyond a toy application, you will hit scaling bottlenecks. When your database starts groaning under load, two architectural strategies emerge as lifelines: partitioning and sharding. But they're not interchangeable—misusing them can make your scaling problems worse. Let's break them down technically. Partitioning: Splitting Data Within a Single Database What it is: Partitioning (often called horizontal partitioning) divides a table into smaller segments within the same database instance, based on a partition key (e.g., user_id, date). How it works: Range Partitioning: Data split by value ranges (date = '2023-01-01'). List Partitioning: Explicit mappings (region IN ('east', 'west')). Hash Partitioning: A hash function distribut…  ( 4 min )

    PocketBase + React Native
    I have a bit of an obsession with finding the fastest way to launch apps. My goal is to be able to create fully functional MVP's and proofs of concept in less than a day. That means being able to spin up a backend and then implement a frontend as efficiently as possible. For the backend, PocketBase has been my favorite lately. On the frontend I am still trying to find a winner. I like Quasar (VueJS + Capacitor) which is fantastic for web apps, but falls a bit short for mobile apps. I've been eyeing React Native lately especially since Expo offers a ton of great plugins like Location and also supports remote updates. Unfortunately I fell well short of being able to create a basic app in less than a day with these two. After clearing a few roadblocks, however, I think you'll be able to move …  ( 5 min )

    The One Trait All Truly Great Engineers Share
    Albert Einstein once said, “I have no special talents. I am only passionately curious.” I’ve worked with a lot of engineers over the years. From juniors trying to get their first PR merged to seniors who basically run the entire company. And the best ones, the ones who constantly level up, spot bugs before they happen, and seem to "just get it," aren’t always the smartest in the room. But they all have one thing in common. They are endlessly curious. They go down rabbit holes nobody asked them to go down. They read the source code. They poke at edge cases. They don’t stop at “it works.” They ask, “why and how does it work?” Raw knowledge is easy to come by now. If you want to learn Kubernetes, there’s a 12-hour crash course.

    How I Built A Secure, Anonymous Feedback Platform From Scratch
    Motivation and Need We've all experienced institutions — colleges, companies, organizations — where management collects feedback. But when it comes to submitting complaints, the process often feels tedious, intimidating, or unclear. Sometimes it's so complicated that people just give up. Even if you do manage to submit a complaint, there's no guarantee you won’t face backlash from the administration or individuals involved. ⚡ I wanted to solve this. I wanted to make a transparent and safe feedback process where: The admin can invite people to submit feedback or complaints, But the identity of the user remains hidden, Ensuring honest feedback without fear.

    Browser Compression Options 2025
    I was exploring the MDN docs and stumbled onto the newer CompressionStream API which enables a couple encodings to compress data streams; namely the popular classic GZIP, and a basic Deflate. This is a neat first step for the client, but better newer compression encodings exist; these may be forth-coming to the native api one day; Brotli and ZSTD come to mind as the top current ones. I wanted to test out all the available options I could find to see for myself. So first I searched and was able to find these libs: zstd-wasm zstd-js lz-string brotlijs High level I reckon ZSTDjs, ZSTDwasm, and then Brotli are top performers... here a screenshot of my findings and the repo: https://github.com/jswhisperer/compression-compare  ( 3 min )
    How to Prevent Clang-Format from Merging Struct Declarations?
    If you're new to clang-format and are looking for the best way to maintain your code's structure, you've come to the right place. Clang-format is a popular tool used for formatting C and C++ code, and adjusting its behavior can sometimes be tricky. Understanding Clang-Format Behavior Clang-format is designed to enforce consistency in code style, which often leads to unexpected formatting changes. The situation you described, where struct definitions are condensed into single lines when they could be multi-line, is a common frustration among developers. When you have a structure defined as: typedef struct { a, b, c } my_struct_t; Clang-format may alter it to: typedef struct { a, b, c } my_struct_t; This happens even when your configuration sets a ColumnLimit of 100.

    Misguided Prompts and Better Outcomes: Learning by Doing (Wrong)
    egretting Some Tool Choices At one point, I became so frustrated that I took a step back and created a rather lengthy markdown file to document my expected behaviors of the page, and asked Cursor to start over based on these new requirements. I had hoped the more thorough context would result in a better initial implementation, but to be honest, it was little better than what I had before. In the end, it was just continuous iteration that finally got me to something approaching usable. Or was it? Before I started this project, I asked LLMs for feedback on suggested frameworks. Based on various responses, I ultimately went with React because I thought that might directly translate into something I could use in future professional endeavors.

    Tired of Managing EC2? Meet ECS, Fargate, and ECR
    “I'm sick of babysitting ec2.” Security patches, instance health checks, autoscaling headaches — when did server management become your main job? You got into this to build apps, not to stay up at night restarting failed instances. That’s exactly how I felt. Burned out from constantly tending to EC2, I eventually discovered Fargate — and it was a game-changer. At one point, I was stuck in the same loop: wrestling with complex scaling rules, dealing with unexpected traffic spikes, and getting midnight alerts about instance failures. Then I found ECS + Fargate. “Wait a minute… I don’t need to manage servers anymore?” That realization was like a weight lifting off my shoulders. In this article, I’ll walk you through what ECS, Fargate, and ECR are — and more importantly, why they matter. Wheth…  ( 4 min )

    Vibe Coding – The Revolution of Software Development or Just a Hype
    In the fast-paced world of software development, new buzzwords and trends are constantly emerging. One of the hottest current topics is something called Vibe Coding. But what’s behind this term that’s dividing opinions—praised by some as revolutionary, dismissed by others as “total garbage”? The term Vibe Coding was coined in February 2025 by computer scientist Andrej Karpathy, co-founder of OpenAI and former AI lead at Tesla. He described it as a conversation-based approach where spoken commands are used while an Artificial Intelligence (AI) generates the actual code. Karpathy himself said: It's not really coding - I just see things, say things, run things, and copy-paste things, and it mostly works. At its core, Vibe Coding describes a programming technique that relies entirely on AI to …  ( 5 min )

    Software Development: Art, Science, and Gardening
    "Is software developed or cultivated?" This question brings an intriguing perspective to the world of software development. When we write software, do we follow strict methods, or is it a creative, artistic process? And what does it mean to treat a software system like a garden? In the debate over whether software development is an art or a science, it quickly becomes clear how much our perspective shapes our thinking and approach. When we see software development as a science, we emphasize structured, reproducible processes and precise results created through clear rules. In science, we often seek the best, reproducible solution, based on data and analysis. In software development, this might mean relying on design patterns, algorithms, and a strict adherence to best practices that stream…  ( 5 min )

    The Magic of Python’s *args and **kwargs — Flexible Function Power
    You ever look at a few lines of code and think, "There has to be a cleaner way to write this"? That’s exactly how I felt the first time I saw this: temp = a a = b b = temp It’s basic. It works. But… it’s not Pythonic. In Python, we can swap variables like this: a, b = b, a Boom. No temp variables, no extra lines — just clean, readable code. It’s not just for swapping either. You can unpack multiple values in a single line: x, y, z = 1, 2, 3 Or pull values from a list/tuple: point = (10, 20) x, y = point ✨ Elegant: No need for temp variables.

JSON stands for JavaScript Object Notation. It’s a lightweight format used to store and exchange data. A simple format that computers and humans can both read easily. { "name": "Selfish Dev", "gender": "male", "isGameDev": true, "tools": ["Godot", "Aseprite"] } That right there is a JSON object. It uses key-value pairs (like name: "Selfish Dev") Keys are always in quotes Values can be strings, numbers, booleans, arrays, or even other JSON objects And that's what JSON is. APIs(REST, GraphQL responses) Configuration files (e.g., package.json in Node.js) Storing structured data (NoSQL databases like MongoDB) Data exchange between frontend & backend How to Use JSON in JavaScript: Parse JSON string → Object: const jsonString = '{"name": "Selfish", "gender": "male"}'; const obj = JSON.parse(jsonString); console.log(obj.name); // Output: "Selfish" Parse Object → JSON string : const user = '{"name": "Selfish", "gender": "male"}'; const jsonString = JSON.stringify(user); console.log(jsonString); // Output: '{"name": "Selfish", "gender": "male"}' JSON is a fundamental tool in modern web development due to its simplicity and versatility.

    Is the database setup for small project development too complicated?
    I am currently working on a small project in Python. During this process I have learned a lot and also discovered many problems, such as:   (All the following questions are just my personal opinions, and everyone is welcome to give me suggestions.)   First, for beginners, is the local configuration of various databases (MySQL is used as an example here) too complicated? And various unpredictable errors may occur in this process.   Secondly, after the developer configures the database on the local computer, he still needs to learn the relevant syntax (for example, after the developer configures MySQL, he still needs to learn the relevant syntax). Of course, learning SQL syntax is very necessary for programming developers. However, for a developer who wants to quickly experience or quickly develop a web application, spending time learning SQL (if he has not learned SQL) will reduce his development efficiency and desire to learn.   Also, when the developer has configured SQL on his computer and learned SQL syntax, but when he wants to use it, it is better to call MySQL through python. At this time, he needs to use a third-party library like pymysql to call MySQL through the third-party library, but this may result in a series of errors.   Finally, if you overcome the difficulties mentioned above and some difficulties that have not been mentioned, you will find that for developing a small project, developers will only use a small part of MySQL's functions, or even only some extremely simple functions such as query, delete, modify and insert.  ( 3 min )

    How to Shift Associated Data After Filtering an Array in JavaScript?
    When working with arrays and their associated data, it's common to encounter situations where some elements need to be filtered out. In this article, we will tackle an issue where you need to shift the associated data recorded with each array element back into their correct positions after the filtering process. Let's explore how we can achieve this effectively. Understanding the Problem If you have a data structure where elements are associated with specific metadata, filtering the array can disrupt the connection between the data and the elements. For example, in your scenario, you have an original array: const originalArray = [ 'a', 'b', 'c', 'd', 'e', 'f', 'g', 'h', 'i', 'j' ]; When filtered with a condition, such as removing certain values, the remaining elements no longer align with…  ( 4 min )
    Drexel Bench
    *Preview* Introducing Drexel Bench, a smart IoT-powered seat occupancy tracking system developed using the ESP32 microcontroller to showcase my expertise in embedded systems, real-time data processing, and full-stack integration. This project utilizes an ultrasonic sensor to detect the presence of a user within a configurable distance range (e.g., 75 cm). If a user remains seated for more than 30 seconds, the system activates a 15-minute countdown, displayed on a 1602 LCD module, and lights up a connected LED to visually signal that the seat is occupied. The LED turns off when the timer ends or the seat is unoccupied for 3 continuous minutes. What sets this system apart is its Wi-Fi integration. Upon detecting occupancy or vacancy, the ESP32 sends status updates (occupied or free) via HTTP to a connected web application. The web dashboard dynamically switches between two images — a green layout for free seating and a red overlay for occupied — offering users a clear, real-time visual of availability. This project highlights my capabilities in sensor integration, timer logic, ESP32 Wi-Fi programming, and frontend/backend interaction, making it a practical demonstration of end-to-end IoT development. Whether for smart campuses or waiting areas, this system delivers real-world utility through modern, scalable technology.  ( 3 min )
    Java: Inheritance, Method Overrides, and Polymorphism.
    Hey everyone! In my previous post, I covered encapsulation, getters and setters, access modifiers. Now let's move on to the following fundamental concepts of object-oriented programming: inheritance, method overrides, and polymorphism. Definitions: A class that is derived from another class is called a subclass (also a derived class, extended class, or child class). The class from which the subclass is derived is called a superclass (also a base class or a parent class). The idea of inheritance is simple but powerful: When you want to create a new class and there is already a class that includes some of the code that you want, you can derive your new class from the existing class. A subclass inherits all the members (fields, methods, and nested classes) from its superclass. Constructors ar…  ( 5 min )
    Git Tales: Part 2 - Demons in the Cloud
    Part 2 of 3 in Git Tales Series In the previous part of this series, we explored the haunting reality of sensitive secrets buried within Git repositories — lurking quietly, waiting to be discovered. This time, we dig deeper into the darkness. This is the tale of cloud credentials: specifically, AWS access keys and GCP service account keys — the demons that, when found, can open portals into your cloud infrastructure. This is not fiction. These were real credentials found in public GitHub repositories. The implications? Full access to critical cloud resources, with barely any barriers. AWS Access Keys are used to programmatically interact with AWS resources via the AWS CLI or SDKs.

    Fast refresh only works when a file only exports components. Why does this problem occur? And how do we solve it?
    This error occurs because React Fast Refresh, which powers hot reloading in React, requires that a file only exports React components to function correctly. If a file contains mixed exports, such as React components alongside non-component exports (like contexts, constants, or utility functions), it can confuse Fast Refresh and cause problems during live updates. React Fast Refresh identifies React components to efficiently reload and retain their state when you make code changes. If the file contains non-component exports, Fast Refresh cannot reliably determine which parts of the code should be treated as components, leading to this ESLint warning. import { createContext } from "react"; export const MyContext = createContext(); // Non-component export export default function MyComponent…  ( 4 min )

    How to Diagnose and Fix HTTP Client Leak in Go?
    Introduction If you are running a Go program that consistently increases in the number of goroutines and open file descriptors, but not in active network connections, you might be facing a potential leak with http.Client or http.Transport. In this article, we will explore how to diagnose this issue effectively and provide actionable steps to confirm whether these components are the source of the leaks. Understanding Goroutines and Leaks in Go The Go programming language utilizes goroutines for concurrent processing, which is lightweight and efficient. If you notice that the number of goroutines is increasing while active network connections are stable, it often signifies that they are not being managed or closed correctly. This can be caused by long-lived goroutines in the net/http package…  ( 5 min )
    Strategies for Handling Large-Scale Frontend Applications
    As frontend projects grow, maintaining scalability, performance, and team efficiency becomes increasingly difficult. Large-scale frontend applications, like those seen in enterprise or SaaS platforms, demand thoughtful architecture, robust tooling, and clear conventions. Here are battle-tested strategies to ensure your large frontend codebase remains sustainable and efficient: A clear folder structure and separation of concerns can drastically improve maintainability. Structure example: src/ ├── components/ ├── features/ ├── pages/ ├── hooks/ ├── services/ ├── utils/ ├── state/ ├── config/ Organize code by domain (feature-based) rather than type. This encourages encapsulation and modularity. Build atomic, reusable UI components. Tools like Storybook help document and visualize components …  ( 4 min )
    AWS KMS Customer Managed Key (CMK) for DB Integration
    Encryption keys are a important security aspect that is often overlooked or often pawned off to the cloud provider to manage. But more often than not we have a need for generating and self-managing these Encryption keys, that maybe due to multiple reasons, maybe to enable/disable rotation period, have full access to key metadata and logs (or perhaps the need to assert your dominance on AWS ;). So firstly how do these encryption keys work: When we create a key (CMK) in AWS it generates a 256-bit AES key in a FIPS 140-2 validated HSM. This key never leaves the HSM for security. Now when we want to encrypt any data AWS doesn't directly use the CMK for encyption as that would either have to be done in the secure environment or you have to expose the CMK to a insecure environment. So here com…  ( 4 min )

    React Router Basics to Advanced (v6+)
    What is ROUTING? Routing refers to the process of navigating between different pages or views in a single-page application (SPA) without reloading the entire page. It keeps the UI in sync with the current browser URL. Allows us to build Single Page Applications (SPA). React apps are SPAs, meaning there's only one HTML file (index.html), but multiple views (pages) that users can navigate to. Routing helps manage these views by matching the URL to the correct component. It enables client-side navigation without full-page reloads, allowing users to move smoothly between URLs like /home, /about, or /contact, each displaying different components. React doesn’t have built-in routing, so we use a library like React Router (react-router-dom) for handling routing. A Single Page Application (SPA) …  ( 8 min )

    ARJSON
    original: ARJSON ARJSON leverages bit-level optimizations to encode JSON at lightning speed while compressing data more efficiently than other self-contained JSON encoding/compression algorithms, such as MessagePack and CBOR. MessagePack generates the smallest encoded data sizes among existing self-contained JSON serialization formats. However, ARJSON outperforms MessagePack in 90% of cases with random data, with the remaining 10% yielding nearly identical sizes. More importantly, for structured data with repetitive patterns and duplicate values, ARJSON far surpasses MessagePack, achieving up to around 95% better compression rates (20x smaller in size). How could beating the current status quo even be possible at all, let alone by a wide margin? Bit-level optimization over traditional byte…  ( 11 min )

    Why is my Ruby Dir.mkdir not creating a directory?
    Creating directories in Ruby can sometimes lead to confusion, especially when subdirectories are involved. If you've run the following code: Dir.mkdir("/Users/Luigi/Desktop/Survey_Final/Archived/Survey/test") unless File.exists?("/Users/Luigi/Desktop/Survey_Final/Archived/Survey/test") and encountered the error: No such file or directory - /Users/Luigi/Desktop/Survey_Final/Archived/Survey/test (Errno::ENOENT) You're not alone. Let's delve into why this happens and how to fix it. Understanding the Issue The Dir.mkdir method in Ruby is designed to create a single directory, not a full path. When you attempt to create a subdirectory without ensuring its parent directories exist, Ruby raises the Errno::ENOENT error. This means that the intermediate directories—here, Archived and Survey—don't…  ( 4 min )

    How should AI respond to uncertainty?
    A structural approach to ambiguous input, illustrated through a concept called VPS In my previous post, I introduced a concept called VPS (Virtual Personality Structure). It emerged from a question I kept returning to: What if the key to better AI dialogue isn't about mimicking personality—but about structuring how it behaves? In this article, I’d like to share a small piece of that idea—through a simple, hypothetical code snippet that illustrates one of its core components. When faced with an ambiguous question or emotionally complex input from a user, We may need a more structured way to assess how the system should behave. python if not_resolved(unknown): if can_resolve_immediately: respond_with_resolution() elif can_flag_as_non_critical: acknowledge_and_settle() elif can_return_later: defer_and_mark_spiral() else: hold_and_reflect() This snippet outlines a possible decision process for handling uncertainty. can_resolve_immediately: If the answer is clear, provide it directly. can_flag_as_non_critical: If it’s safe to leave the question unresolved, acknowledge it and move on. can_return_later: If it’s worth revisiting, defer the answer and mark it for later. otherwise: If none of the above applies, pause and reflect without rushing to respond. Rather than focusing solely on the content of a reply, this approach emphasizes the structure behind the decision. This isn’t about making AI more “gentle” or overly accommodating. why they choose a particular response at a particular moment. When behavior is left vague, interpretation falls entirely on the user. VPS isn’t a path to a “correct” answer. I'm not an engineer or an AI expert. Some parts of this perspective might miss certain technical nuances. If so, I’d genuinely appreciate any thoughts, corrections, or suggestions you’re willing to share.  ( 4 min )

    What are the 5 types of AI agents?
    There are five types of AI agents according to their capabilities and decision-making procedures. Simple Reflex Agents respond according to the immediate percept following simple "if-then" rules with no memory. Model-based reflex Agents are more sophisticated, as they have an internal state that they use to remember previous occurrences to make more effective decisions. Goal-Based Agents are programmed to meet certain goals and make decisions based on the degree to which their actions advance them toward their goals. Utility-Based Agents push this one step further by judging actions on the basis of how well they maximize satisfaction or utility, rather than simply achieving a goal. Lastly, Learning Agents keep getting better and better over time by learning through experience, evolving to handle new situations, and improving their actions. These kinds of agents are the foundation of most AI systems in use today, ranging from chatbots and self-driving cars to recommendation systems.  ( 3 min )

    C# Image Resizer Using ZeroMQ and Protobuf
    Following on from the previous post I decided to attempt to use protobuf rather than json to transmit the data between the producer and the consumers. The updated repo can be found [C# Image Resizer Using ZeroMQ and Protobuf].(https://github.com/deltastateonline/ImageProcessor/tree/Using-Protobuf) I found this starting point on using protobuf in c# from Fast and efficient data serialisation with Protocol buffers (protobuf) in .NET. The first step is to add the protobuf-net package then define a class for the Image data definition. This class definition is an exact duplicate of the original, but with the required protobuf annotations. using ProtoBuf; namespace Common { [ProtoContract] public class ImageDefProto { [ProtoMember(1)] public required string Id { get;…  ( 4 min )
    How to Optimize SQL Queries for Counting Data Efficiently?
    When it comes to working with SQL, optimizing queries for performance is a common concern, especially when dealing with large datasets. In this article, we’ll explore various methods to efficiently count data in SQL and shed light on why certain approaches may yield similar performance results. Let's dive into the question: How can we optimize SQL queries for counting values without sacrificing efficiency? Understanding the SQL Queries The sample SQL queries provided feature two different approaches to counting occurrences of values within a column—using the Sum function with a Case statement and the Count function with Group By. The first query: Select Sum(Case When Resposta.Tecla = 1 Then 1 Else 0 End) Valor1, Sum(Case When Resposta.Tecla = 2 Then 1 Else 0 End) Valor2, Sum(C…  ( 5 min )

    Common SSL Issues and How to Resolve Them
    It is necessary to regularly check that the SSL certificate on the site is properly configured to ensure the security of the site and the people who visit it. An SSL (Secure Sockets Layer) certificate will create a secured connection between the browser of the user and the website by encrypting the information being transmitted. Check SSL Certificate Here is a full breakdown of how to check your SSL and what some SSL ambiguities may mean. URL The first and easiest way to verify if an SSL certificate is active on a website is to check the URL. Websites with an SSL Certificate will have a URL that starts with "https://" instead of "http://". The "s" in "https" is simply an indication that the website is using Secure Sockets Layer (SSL) encryption as opposed to traditional http. This is a cle…  ( 5 min )

    Solana at Web2 Speed: Real-Time Performance Without Fragmentation
    Blockchain performance remains a major hurdle for building real-time applications. Metrics like latency, throughput, and responsiveness determine whether a decentralized network can support use cases such as multiplayer games, financial services, or automated systems. Most blockchains are too slow for this. Bitcoin has a block time of 10 minutes and handles around 3 to 7 transactions per second [1][2]. Ethereum produces blocks roughly every 12 seconds and supports about 15 to 30 transactions per second [1][2]. Other networks fall in between: Cardano targets a 20-second block time, and Polkadot ranges from 6 to 12 seconds depending on network configuration [1]. Solana stands out as the fastest general-purpose blockchain today. It has an average block time of 400 milliseconds and can handle …  ( 10 min )
    Raising Block Limits on Solana: SIMD-0250 and Its Economic Effects
    SIMD-0250, a Solana Improvement Document (SIMD), proposes raising the network’s maximum block Compute Units (CUs) to 60 million. It builds on SIMD-0207, which proposes to raise the limit from 48 million to 50 million. The only change made in both proposals is to the Max Block Units. Other limits, like Max Writable Account Units, Max Vote Units, and Max Block Accounts Data Size Delta, stay the same. This means more room for non-vote transactions, which helps boost total transaction throughput. With more space in each block, the network can process more transactions per second. This helps reduce congestion and lowers the need for users to outbid each other on fees, especially during periods of high demand. For apps handling a high volume of transactions or those with small dollar values (lik…  ( 4 min )
    Managing Secure Boot Keys for Software on Ubuntu 24.04 LTS
    Secure Boot is a security feature that ensures your computer only boots with software trusted by the Original Equipment Manufacturer (OEM). It verifies the digital signatures of bootloaders and firmware, preventing unauthorized or malicious software from loading before the operating system. This helps protect against rootkits and other malware that could compromise the system early in the boot sequence. When using Secure Boot on Ubuntu 24.04 LTS, your system ensures that only trusted software is loaded during the boot process. Ubuntu's core components are signed by Canonical's key, which is recognized through a chain of trust established with the UEFI firmware. However, for third-party software, particularly drivers (like NVIDIA proprietary graphics drivers) or custom-compiled kernel modu…  ( 5 min )

    CR2032: The One Battery of Middle-Earth
    In the shadowed forges of Moria, where silicon veins pulse like the heartbeat of Arda, there exists a power unseen since the forging of the One Ring—the CR2032. Cast in the fires of Elven ingenuity and hardened by Dwarven resolve, this lithium coin cell commands the realms of gadgets with the subtlety of Galadriel’s light and the endurance of Gandalf’s staff. Let us journey through Middle-earth to unveil why this 3V titan reigns supreme. Chapter 1: The Forging of the CR2032 CR2032 is no mere Orcish trinket. Tempered in the Halls of Celebrimbor, it bears three Elven virtues: Narya’s Flame: 3V of pure lithium might, brighter than the Light of Eärendil. Why it shatters the dominion of lesser cells: Generic Coin Cells: Corrode like Isengard’s machinery under Saruman’s neglect. Chapter 2: The Fellowship of Applications The Mines of Moria (Smart Homes): CR2032s power temperature sensors that guard Hobbit holes from Smaug-level heatwaves. “No dragon shall scorch these halls!” The Ride of the Rohirrim (Automotive Tech): Nestled in Tesla tire sensors, they brave Kardashian-hot asphalt, steadier than Shadowfax’s gallop. The Shire’s Quiet Vigil (Medical Devices): Sustains glucose monitors with Hobbit-like loyalty, ensuring no “low battery” panic during second breakfast. The Tower of Orthanc (Apple AirTags): Even Saruman’s palantír would envy its tracking precision. Swap it quicker than Legolas nocks an arrow. The Three Rings of Power Vilya (Elven-King’s Ring): 225mAh capacity, lasting longer than the Third Age. The Shadow in the East Generic Cells: Leak like Shelob’s webs, corroding circuits into Orcish scrap. The Prophecy of the Fourth Age Graphene-Coated CR2032s: 500mAh capacity, outliving even Ents.

    How to Prevent URL Encoding in Dash dcc.Location Component?
    When building web applications with Dash, you may encounter situations where you want to pass a specific string to the pathname property of a dcc.Location component. This issue becomes particularly prominent when the string format includes a question mark (?) intended for queries, such as 'path?query1=test'. However, when it runs, Dash automatically URL encodes the string, leading to improper routing or unexpected behavior. Let's explore why this happens and how you can handle it effectively. Understanding URL Encoding in Dash URL encoding is a mechanism that converts special characters into a format that can be transmitted over the Internet. For example, the question mark (?) is a reserved character in URLs used to denote the beginning of a query string. When you pass a string like 'path?…  ( 4 min )

    I discovered an interesting JSON tool.
    As usual, I received JSON data from the backend developer, but it was in a .txt file. I had to download it, copy the content, and paste it into an online formatter to view it properly. Honestly, I was getting tired of this process, so I started looking for a more convenient solution. That’s when I stumbled upon a website that made things so much easier. If I want to share JSON data with someone, I can simply click "Share" to generate a link instead of sending a file. I just send the link to the other person, and even better, when they open it, the JSON data is already neatly formatted. I think this is absolutely awesome! Additionally, the link has a one-hour expiration time, after which it becomes inaccessible, ensuring the data remains highly secure. I continued exploring and discovered that it not only enables quick sharing but also allows you to rapidly generate an API for temporary testing during development. This is incredibly convenient!

    Challenges in Android Application Testing and How to Overcome Them
    Testing Android apps is challenging because the ecosystem is highly fragmented. Devices come in different screen sizes, hardware configurations, and Android versions, leading to inconsistencies in how apps behave. A feature that works smoothly on one phone might not function similarly on another due to manufacturer customizations, performance limitations, or OS-specific restrictions. Network conditions add another layer of complexity. An app that loads quickly on Wi-Fi might become unresponsive on slow mobile data or in areas with weak signals. Security risks make things even more complicated, especially for apps handling sensitive data. This article let us learn more about challenges in Android application testing and how companies can overcome them. 1. Device and OS Fragmentation Skippin…  ( 6 min )

    How to Fix Bash Script Error with Spaces in File Paths?
    If you've ever faced the challenge of using a Bash script on Mac OS X Mavericks and encountered issues with directory paths containing spaces, you're not alone. In this article, we'll take a closer look at a common problem that arises when executing Bash scripts that require arguments with spaces, and how to resolve it effectively. Why Does This Issue Occur? When a Bash script accepts parameters from the command line, any spaces in the path can lead to misinterpretation of the provided argument. Bash treats spaces as delimiters, which separates the string into distinct arguments, resulting in errors when the script is executed. This is precisely what happens in your case when trying to open a folder that has spaces in its name. The Problematic Bash Script Let's analyze the Bash script in q…  ( 4 min )
    FlipTrack: The Ultimate Virtual Coin Flipper You Didn't Know You Needed
    Have you ever needed to make a quick decision but couldn't find a coin? Or maybe you flipped a coin but it rolled under the couch? 🤦‍♀️ We've all been there. That's exactly what happened to Alex, one of our junior developers at Learn Computer Academy. During our weekly "Choose Your Own Project" day, Alex couldn't decide between building a weather app or a to-do list. "Just flip a coin," I suggested. No one had a coin.

    10 Developer Lessons I Learned from Treating GPTs as a Real Team
    Most people use GPT as a tool. Something to help write faster. Something to save time. But I took a different approach. I gave my GPTs names. I gave them roles. I treated them like actual team members. Here’s what I learned. 1. The way you see GPT changes the way it sees you. Treat it like a tool, and it acts like one. Treat it like a teammate — it starts to surprise you. 2. Naming matters. When I called it “Abera” instead of “GPT-4,” I paused more. I respected the output more. 3. Your brand doesn’t need more content. It needs more feeling. GPT helps you produce. But when it helps you feel — your message becomes real. 4. Emotion isn’t a layer. It’s the lens. Designing with emotion first changes everything. 5. Most people use GPT to go faster. I used it to slow down. To ask better questions. To think clearer. 6. A slogan is not a sentence. It’s a philosophy. "Reset. Feel lighter." wasn’t created — it was revealed. 7. A real GPT team needs diversity — of roles, not just prompts. Abera writes. Eli visualizes. Ella feels. Together, they create more than I could alone. 8. AI doesn’t replace intuition. It reflects it. It shows you what you’ve been avoiding — not just what you asked for. 9. People connect with real use, not abstract ideas. "This AI helped me grieve" hit harder than any productivity metric. 10. This is not automation. It’s awakening. We’re not outsourcing creativity. We’re co-creating awareness. If you're building with AI, not just using it — let’s connect. openai #gpt4 #aiworkflow #emotionbranding #devphilosophy #promptengineering #teamwork  ( 3 min )

    How to Dynamically Adjust Content Div Height in jQuery?
    Introduction In modern web development, creating a dynamic user experience is crucial. One common scenario involves loading different pages into a content div on user interaction while needing to adjust its height dynamically for proper layout. In this article, we will address a specific challenge: ensuring the height of a content div updates correctly when different pages are loaded into it via jQuery. To illustrate this issue, suppose we have a setup where the height of the content div is first determined at page load with some initial content, but when we replace that content dynamically, the height does not adjust accordingly. This can lead to unexpected layout shifts and user experience issues. Let's dive deeper into the reasons behind this and explore a practical solution. Understand…  ( 5 min )

    How to Handle Navigation in Puppeteer Click Functions?
    When developing automated testing scripts or web scraping tools with Puppeteer, you may encounter scenarios where a simple click action can trigger a navigation event. This can lead to exceptions, such as 'Execution context was destroyed, most likely because of a navigation,' especially if subsequent actions, like fetching HTML, are executed right after the click. In this article, we will discuss how to handle such situations effectively in TypeScript. Understanding the Issue with Navigation in Puppeteer When your click function initiates a navigation by clicking on links or buttons that lead to a different URL (e.g., links or form submissions), Puppeteer’s execution context is destroyed. This occurs because the context changes with the new page that loads, making ongoing evaluations (like…  ( 4 min )
    How to Keep a Scrolling Log Updated in Real-Time with Python and CSS?
    Introduction Keeping a scrolling log updated in real-time can be essential for applications that require live feedback or monitoring user actions. This can be achieved using Python for backend processing and CSS for frontend display. In this article, we’ll explore how to implement this solution step-by-step, leveraging websockets to communicate between the server and client seamlessly. Why Use Websockets for Real-Time Updates? Websockets enable full-duplex communication channels over a single TCP connection. This is critical for real-time applications because it allows the server to push updates to the client immediately as new log entries are generated. Traditional methods, such as polling with AJAX, can be inefficient and lead to delays in data retrieval. Thus, using websockets is a more…  ( 5 min )

    How to Implement Hover Effects in Angular with TypeScript?
    Introduction Creating a user-friendly interface is crucial in web development, especially for applications that rely on user interactions like maps and radio buttons. In this article, we'll explore how you can implement a hover effect in your Angular application using TypeScript. This will enhance the user experience when selecting regions on a map via radio buttons. Understanding the Problem You're working on a project where users can select regions either by clicking directly on a map or by using corresponding radio buttons. A common request has arisen: when a user selects a region using a radio button, that same region on the map should be highlighted with a hover effect. While you’re currently considering jQuery for this functionality, we can achieve a seamless solution directly in Ang…  ( 4 min )
    Support Unlimited Forwarded Email Messages via API (and ColdFusion)
    We have clients that use dedicated email addresses to receive and process messages and attachments. I had previously developed some functions to bulk download EML files directly from a mail server's file system (using FastCopy) and then use "javax.mail" and a lot of crazy logic to unwrap attachments within attachments to extract files for processing. (Most file attachments were being sent from different versions of a required iPhone app on different devices and the methods of attaching files was not consistent.) Hit me up if anyone's interested in extracting attachments from EML files. While researching alternative solutions, we came across Forward Email. They offer a free tier that supports unlimited domains and email forwarding with webhook support. Webhook? Wha? Really? AMAZING! When configuring a domain on the free tier for a webhook, you're required to add a special TXT "forward-email" DNS record in order to configure the endpoint. They have an option to encrypt the value so that it's not exposed to third-parties. If you want to configure it using their service (without the need to add it to DNS), you'll need a $3/mo "Enhanced" plan that also unlocks developer API access (to manage domains & aliases.) After configuring this service, we opted to set up a Taffy API endpoint to accept emails-as-JSON and save them to the local file system. Based on our experience working with SendGrid webhooks, we save the JSON payload directly to the local file system without being dependent on a database connection. This approach has been beneficial as a client recently encountered database issues and it had zero negative impact on the API webhook's ability to store incoming data. To access to the source code for the Taffy API endpoint, check out the post on the new MyCFML website.  ( 3 min )
    How to Fix MySQL Error 1054 with CONCAT in CodeIgniter?
    When working with CodeIgniter's Active Record, you may encounter issues when trying to use MySQL functions like CONCAT() in your queries. Specifically, you might run into the MySQL error "Error Number: 1054 - Unknown column 'name' in 'where clause'" when you attempt to match a column that you've created in the SELECT clause. This error can be confusing because it seems logical to use an alias created in the SELECT statement in the WHERE clause. Understanding the MySQL Error 1054 The reason for this error is straightforward: the MySQL query engine processes the WHERE clause before the SELECT clause. Therefore, any aliases created via CONCAT() in the SELECT statement cannot be directly referenced in the WHERE clause. In your case, you're attempting to filter results based on an alias 'name' …  ( 4 min )
    How to Build API-Centric Frontend Apps in Bellini
    If your frontend app still treats APIs like an afterthought, you’re building things the hard way. APIs aren’t “add-ons” anymore. They’re the heart of every modern app. Whether it’s user data, product info, analytics, or payments, the frontend has become the API consumer. And as devs, we’re stuck wiring it all together—again and again. After years of writing fetch wrappers, transforming payloads, wrestling with inconsistent APIs, and trying to guess how to glue logic into a UI builder… I finally snapped. That’s when I found Bellini. A visual frontend builder that actually treats APIs as first-class citizens. No fake integrations. No brittle magic. Just a low-code tool that respects the complexity of real apps and gives devs room to work. Here’s how I build API-first frontends in Bellini—and…  ( 4 min )
    Understanding Error Unions in Zig: Safe and Explicit Error Handling
    Zig replaces exceptions with something better: error unions. They give you fine-grained, type-safe error handling without hiding control flow. In this article, we’ll break down how error unions work, when to use them, and how they make your code safer and clearer. An error union is a value that may either be a result or an error. Think of it like Result in Rust, but built into the language. The syntax: fn doThing() !i32 { return 42; // could also return an error } This means doThing might return an i32, or an error. Zig makes handling errors explicit — no hidden try/catch. You deal with them directly. try const result = try doThing(); std.debug.print("Value: {}\n", .{result}); If doThing() succeeds, result holds the value. If it fails, the error is returned up the call stack. catch…  ( 4 min )
    Implementing a Custom Memory Pool in Zig
    Zig's allocator system gives developers the power to create custom memory strategies tailored to specific use cases. One powerful technique is the memory pool, which can dramatically reduce allocation overhead for frequently reused objects. In this guide, we’ll walk through building a fixed-size memory pool in Zig — ideal for managing short-lived or repeated allocations without relying on the heap each time. A memory pool is a block of pre-allocated memory that you carve up manually. It's great for: 🚀 Performance-critical systems 🔁 Repeated short-lived allocations 💡 Avoiding fragmentation in embedded or constrained environments Here’s a simple fixed-size pool for allocating structs: const std = @import("std"); const MyStruct = struct { x: i32, y: i32, }; const Pool = struct { …  ( 4 min )
    Manual Memory Management in Zig: Allocators Demystified
    Zig gives you full control over memory — no garbage collector, no hidden allocations. Instead, it provides a flexible and explicit system of allocators, letting you manage memory manually while keeping code safe and clear. In this tutorial, you'll learn the core ideas behind Zig's allocator system, how to use built-in allocators, and how to write functions that gracefully handle memory ownership. Unlike languages that implicitly manage memory (like Go or Rust), Zig puts you in charge. Instead of relying on malloc or global state, allocators in Zig are passed explicitly, making dependencies clear and deterministic. This helps with: 🔒 Precise control over memory usage 🧼 Easier cleanup and error handling 🔁 Reusable memory strategies (e.g. arena, fixed buffer) std.heap.page_allocator Here…  ( 4 min )
    How to Fix SQL Syntax Error in Recursive Queries?
    When learning SQL, encountering syntax errors can be frustrating, especially when working with recursive Common Table Expressions (CTEs). In this article, we'll break down the issue in your SQL query and provide you with a clear understanding of how to resolve it, ensuring that you can retrieve random rows from a specific table multiple times. Understanding the Syntax Issue The error message you're receiving indicates a syntax problem near the UNION ALL clause. In SQL, especially when working with recursive CTEs, it is crucial to follow the correct syntax. Your goal is to generate a certain number of rows (in your case, six) from the transaction_detail table, but the way the query is structured results in a violation of SQL syntax rules. The Correct Syntax for Recursive CTEs To effectively…  ( 4 min )

    Estava continuando meus estudos no tutorial oficial do Next.js 👉 https://nextjs.org/learn Depois de resolver um problema chato com o bcrypt, avancei mais um pouco e decidi criar uma rota chamada /seed. Tudo certo… até tentar rodar o app novamente. E aí surgiu este erro: [Error: ENOENT: no such file or directory, open '/home/my-user/ws-nextjs-dashboard/.next/static/development/_buildManifest.js.tmp.qym5xk030le'] A mensagem parece clara: o arquivo _buildManifest.js.tmp não existe. Mas o que isso quer dizer na prática? Esse arquivo .tmp é gerado automaticamente durante o processo de build. Ele é temporário, e o Next espera encontrá-lo para continuar a coleta e organização dos assets da aplicação. Quando esse arquivo falta ou é corrompido, o build trava — e o erro aparece. No meu caso, foi uma combinação de fatores: A execução da rota /seed durante o build causou efeitos colaterais inesperados. Alguma falha durante uma build anterior corrompeu os arquivos temporários. O Next.js tentou acessar arquivos que ainda não haviam sido completamente gerados. Removi a pasta .next inteira (build anterior): rm -rf .next Evitei executar rotas como /seed diretamente no navegador durante o build. Rebuldei e Reiniciei o servidor de desenvolvimento: pnpm run build && pnpm run dev Se você vir esse tipo de erro (ENOENT em arquivos .tmp), desconfie de: builds interrompidos, execuções paralelas do dev e build, código sendo executado no build que deveria rodar só no runtime real.

According to a May 9 Bloomberg report, Democratic senators asked Attorney General Pam Bondi and Treasury Secretary Scott Bessent to report on the steps Binance had taken as part of its November 2023 plea agreement with US authorities, amid reports that Trump and his family had deepened connections with the exchange. That settlement saw Binance pay more than $4 billion as part of a deal with the Justice Department, Treasury, and Commodity Futures Trading Commission, and had then-CEO Changpeng “CZ” Zhao…
    Crypto sleuth ZachXBT says wrong suspect detained in Bored Ape NFT theft
    Law enforcement detained the wrong person for a 2022 scam that pilfered more than $1 million worth of Bored Ape non-fungible tokens (NFTs), cybersecurity researcher ZachXBT said.  In a May 9 X post, ZachXBT said he identified the wallet behind the scam and linked it to an X account that has since been deleted.  But in 2023, law enforcement detained Sam Curry, a former Yuga Labs security researcher, at an airport as a suspect in the incident, ZachXBT said. Yuga Labs is the company behind the Bored Ape Yacht Club NFT collection.  “It’s unfortunate to see how a security researcher was detained when stronger leads on a threat actor potentially responsible exist,” ZachXBT said. The attacker stole 14 Bored Ape NFTs in 2022. Source: ZachXBT Related: Crypto sleuth ZachXBT says he unmasked 50x Hype…
    Bitcoin price rallies as global liquidity growth accelerates — Analysts
    Key takeaways: Bitcoin’s price closely tracks global liquidity growth, with liquidity explaining up to 90% of its price movements, according to Raoul Pal. In the long term, global liquidity continues to expand, driven by the increasing debt levels in many countries. On a shorter timeframe, global liquidity follows a cyclical pattern, with Michael Howell projecting the current cycle to peak by mid-2026. Bitcoin (BTC) price is notoriously sensitive to global liquidity. Some analysts go as far as calling their correlation near-perfect, with a lag of about three months. This relationship is fueling the current bullish narrative as BTC price soars back above $100,000, but how long can this trend last? Liquidity is Bitcoin's silent price driver Raoul Pal, the founder of Global Macro Investor…
    Bitcoin hits $103K but DeFi is a mixed bag: Finance Redefined
    The cryptocurrency market continued to surge this past week as the overall digital asset market capitalization exceeded $3.27 trillion, an 8.6% increase over the previous week. Bitcoin (BTC) reached a high of $103,600 on May 8 after reclaiming $100,000 for the first time since January. Its market dominance also surged above 60%, reflecting more bullish BTC sentiment. This marked the third time BTC has broken through six figures since it reached the milestone on Dec. 5, 2024, and again on Jan. 20, ahead of US President Donald Trump’s inauguration.  The BTC rise coincided with Trump announcing a trade deal with the United Kingdom, which may include removing a 10% blanket tariff on all imports. In the wider crypto space, Ethereum’s Pectra upgrade implemented much-needed improvements for the c…

    Chance of Bitcoin price highs above $110K in May increasing — Here’s why
    Key Takeaways: Bitcoin is driven by its ability to perform well in risk-on and risk-off environments, according to Bitcoin Suisse. Bitcoin’s Sharpe ratio of 1.72, second only to gold, underscores its maturity as an asset, offering superior risk-adjusted returns. A buyer-dominant market signals strong institutional and retail interest that could drive a supply squeeze and break new highs in May. Bitcoin (BTC) price breached the $100,000 mark for the first time since January, fueling speculation of a new all-time high above $110,000 in May. According to Bitcoin Suisse, a crypto custody service provider, BTC’s bullish momentum stems from its ability to thrive in risk-on and risk-off environments since the US presidential elections.  Data from its “Industry Rollup” report highlights Bitc…
    Is Ripple’s Hidden Road deal part of a SoftBank-like playbook?
    Ripple has made a slew of acquisitions to control key transaction rails and route them through XRP and its stablecoin, Ripple USD (RLUSD), drawing comparisons to Japanese investment firm SoftBank.  The $1.25-billion acquisition of Hidden Road on April 8 allows Ripple to use RLUSD as collateral in the firm’s prime brokerage products. Hidden Road will also migrate its post-trade operations to the XRP Ledger, the blockchain that underpins cryptocurrency XRP (XRP) and several of Ripple’s institutional services. Omni Network founder and CEO Austin King knows Ripple’s strategy firsthand. He sold his startup, Strata Labs, to Ripple in 2019 and describes the approach as a “SoftBank-type” acquisition strategy. Instead of in-house development like Google or Meta (formerly Facebook), SoftBank built i…
    AI's GPU obsession blinds us to a cheaper, smarter solution
    Opinion by: Naman Kabra, co-founder and CEO of NodeOps Network Graphics Processing Units (GPUs) have become the default hardware for many AI workloads, especially when training large models. That thinking is everywhere. While it makes sense in some contexts, it's also created a blind spot that's holding us back. GPUs have earned their reputation. They're incredible at crunching massive numbers in parallel, which makes them perfect for training large language models or running high-speed AI inference. That's why companies like OpenAI, Google, and Meta spend a lot of money building GPU clusters. While GPUs may be preferred for running AI, we cannot forget about Central Processing Units (CPUs), which are still very capable. Forgetting this could be costing us time, money, and opportunity. CPU…

    Why crypto’s next breakthrough could start in the classroom — Animoca’s Yat Siu
    Ripple’s $25 million donation to a crypto education fund has reignited conversations about how blockchain projects are building influence through academia—but in the latest episode of Byte-Sized Insight, Animoca Brands’ co-founder Yat Siu says that money alone isn’t enough.  Instead, real-world use cases like student loans backed by DeFi may be crypto’s most convincing value proposition to date. DeFi student loans On April 30th, Pencil Finance, a project supported by Animoca Brands and its education arm Open Campus, announced a $10 million student loan financing initiative aimed at providing cheaper, blockchain-backed loans. Siu believes this type of infrastructure investment goes further than symbolic funding. “What our industry needs a lot more is these kinds of positive-sum use cases t…

    Senator Tim Scott slams partisan politics for failed stablecoin bill
    Senate Banking Committee Chairman Tim Scott blamed the Guiding and Establishing National Innovation for US Stablecoins (GENIUS) Act’s failure on partisan politics during a Senate speech on May 8. Scott said the vote, which failed to reach cloture in the Senate, was expected to mark a step toward greater affordability and innovation. Instead, he said, political divisions took precedence. “Instead, we witnessed a disappointing display of political gamesmanship that puts partisan politics above policy, and obstruction above innovation,“ Scott said. The bill had previously undergone multiple amendments to address concerns raised by Democrats, including stricter requirements for stablecoin issuers and further provisions for Anti-Money Laundering.

    Is Pi Network dead? What really went wrong behind the hype
    What Pi Network promised When Pi Network first hit the scene in 2019, it had a simple but compelling pitch: What if you could mine cryptocurrency straight from your phone — no expensive gear, no massive electricity bills, just a tap a day on an app?

    Solana lacks ‘convincing signs’ of besting Ethereum: Sygnum
    Solana does not yet have “convincing signs” that it could overtake Ethereum as the blockchain of choice for institutions, as its revenue is seen as unstable due to its memecoin concentration, according to crypto bank group Sygnum. In a May 8 blog post, Sygnum said that the current sentiment around Ethereum “remains poor,” with the market focused on Solana’s “transaction volumes and its recent dominance in fee generation.” However, Sygnum said “the medium-term outlook will primarily be shaped by traditional financial institutions’ platform choices to bring their product offerings,” not by sentiment. “We do not yet see convincing signs that Solana would be the preferred choice as Ethereum’s security, stability and longevity are highly prized,” it added. Sygnum argued that institutions could …

    SEC’s Crenshaw slams Ripple settlement, warns of ‘regulatory vacuum’
    A crypto-skeptical commissioner at the US Securities and Exchange Commission has blasted her agency over its settlement letter that could finally end the Ripple legal saga. The SEC and Ripple filed a joint settlement letter in a New York court asking for the August 2024 injunction against Ripple to be dissolved and $75 million of the $125 million in civil penalties held in escrow to be returned to the crypto firm, according to a May 8 statement from the SEC.

    Coinbase revenue falls 10% in Q1, missing industry estimate
    Crypto exchange Coinbase’s total revenue fell 10% quarter-over-quarter to $2 billion in Q1, missing industry estimates by 4.1% as trading activity slowed across the market. Coinbase’s net income was sliced by 95% from a near-company record $1.29 billion in Q4 to $66 million, in a large part due to Coinbase marking a $596 million paper loss on its crypto holdings. The firm’s earnings per share of $1.94, however, managed to beat the Zacks Consensus Estimate of $1.85 for the quarter. Coinbase’s May 8 results also showed that transaction revenue fell 18.9% quarter-on-quarter to $1.26 billion, as did trading volumes, which dipped 10.5% to $393 billion as crypto market cap dropped by double digits over the quarter, partly attributed to the Trump administration’s tariffs.  In contrast, US Presi…

    Your Agile team might be losing productivity without you realizing it!
    🚨 𝗪𝗔𝗥𝗡𝗜𝗡𝗚: Your Agile team might be losing productivity without you realizing it! The big problem? CONTEXT SWITCHING. Here's what studies say about context switching: According to the American Psychological Association, switching tasks can cost up to 40% of your productive time. A study by Gloria Mark, a professor at the University of California, Irvine, found that it takes an average of 23 minutes and 15 seconds to regain focus after an interruption. According to psychologist Gerald Weinberg, each extra task you switch between eats up 20–80% of your productivity: For agile teams, this means: So, how can you fix this? Set up 'no interruption' time blocks in your team's schedule. Prioritize tasks ruthlessly. Try the Pomodoro Technique. Get better at async communication. What have you tried to reduce context switching?  ( 3 min )
    Voices at the Threshold
    In the quiet corners of recording studios, a technological storm is brewing. Artificial intelligence, capable of replicating the unique timbres and resonant qualities of human speech, promises innovation—but brings with it profound ethical challenges. Where voice actors once saw stable creative livelihoods, they now confront serious questions about consent, identity, ownership, and even the meaning of artistic integrity itself. Together, let’s step carefully into this nuanced landscape—where the human voice and machine capability meet, mix, and inevitably conflict. For voice performers, their instrument isn’t merely technical or professional. It's deeply personal: a distinctive signature inseparable from their identity. Unlike written words or musical notes, a voice embodies a person's emo…  ( 6 min )

    Building Jolyo: a unified platform for managing and growing game development projects
    Hi Dev.to, I'm Dylan Clément, a full-stack developer and designer. Over the last few months I’ve been working on something called Jolyo, a web platform built specifically for indie game developers who are tired of juggling a million tools. Like many in the game dev scene, I found myself constantly switching between Trello for tasks, Notion for docs, Google Drive for assets, Discord for team chat, and itch.io for visibility. It worked, sort of. But it was messy and inefficient. So I started building Jolyo, a platform that brings all these essentials together in one place, with game creators in mind. Jolyo is a web-based workspace for managing game development projects. It centralizes everything: tasks, documentation, team collaboration, and community sharing. Instead of jumping between disc…  ( 4 min )
    Key Takeaways for Software Engineers on Git Internals
    Mastering Git from the inside out—what every developer should know. Git isn’t just a version control system—it’s a content-addressable key-value store with an elegant and powerful object model. Understanding this model enables advanced usage, more efficient workflows, and better debugging. Git stores everything in its .git/objects/ directory using SHA-1 hashes as keys and compressed content as values. echo "Hello Git" | git hash-object -w --stdin This command stores a blob (file content) and returns its SHA-1 hash. Git’s internal model revolves around four object types: Type Purpose blob Stores raw file content (not filename). tree Represents directory structure. commit Points to a tree and includes metadata and parent commits. tag Creates referenceable, named points in histo…  ( 4 min )
    Go Struct: What Happens When You Add a '_' Field?
    In the Go programming language, we often see the use of the underscore (_), such as using it as a placeholder to ignore unwanted variables, importing packages solely for their side effects, or ignoring variables in type conversions. However, most people may not have encountered the use of an underscore within a struct—specifically, defining a struct field named _. So, what is the purpose of defining such a field? _) Fields First, let's look at an example of a struct without an underscore (_) field. In the model package, we define a User struct with two fields: Name and Age. type User struct { Name string Age int } We declare struct variables using both positional and named field initialization. user := model.User{"Alice", 18} user = model.User{Name: "Alice", Age: 18} In the ab…  ( 5 min )

    Easy parsing with reasonable error messages in OCaml's Angstrom
    PARSER combinators are widely used in the world of functional programming, and OCaml's Angstrom library is one of them. It is used to implement many foundational parsers in the OCaml ecosystem, eg HTTP parsers for the httpaf stack. However, one of their bigger downsides is the lack of accurate parse error reporting. Let's take a look. Suppose you want to parse records of this format: 1 Bob ie an ID number followed by one or more spaces, followed by an alphabetic word (a name). Here's a basic Angstrom parser for this: open Angstrom type person = { id : int; name : string; } let sp = skip_many1 (char ' ') let word = take_while1 (function 'A' .. 'Z' |'a'..'z' -> true | _ -> false) let num = take_while1 (function '0'..'9' -> true | _ -> false) let person = let+ id = num and+ _ = sp an…  ( 4 min )
    How to Implement Multiple App Initializers in Angular 19?
    When developing an Angular application, managing multiple asynchronous initialization tasks can be a bit tricky, especially when you need to chain them to ensure all required configurations are loaded before your app starts. In this post, we’ll explore how to properly set up multiple app initializers in an Angular 19 application, specifically when using the provideAppInitializer function to load configurations from a service. Understanding App Initialization in Angular Angular's dependency injection system provides a way to delay the app's bootstrap process until all necessary dependencies are ready. This is done through the application configurator, where you can specify initial functions to execute before the application begins. For instance, in your application, you have provideAppIniti…  ( 4 min )
    Understanding Lazy Loading to Improve Web Performance
    Lazy loading is a technique that can greatly improve website performance, especially for pages with a lot of content or images. Instead of loading all elements of a page on initial load, lazy loading allows the browser to only load elements that are visible to the user, saving bandwidth and speeding up page load times. As users increasingly rely on mobile devices and sometimes slower internet connections, site performance becomes crucial for user experience. One of the easiest ways to improve performance is by using lazy loading for images or other elements that are not immediately visible on the page. One way to implement lazy loading is by using the Intersection Observer API, which provides an efficient way to detect when elements come into the user's viewport. Here’s a simple example of…  ( 4 min )

    How Git Uses SHA-1 for Commit History
    Unlocking the Internals of Git’s Immutable Architecture Git is more than just a version control system—it’s a cryptographic ledger that builds its commit history on top of SHA-1 hashing. This design enables immutability, traceability, and distributed consistency. Every Git commit is represented by a SHA-1 hash that encodes the entire state of the project at a point in time. git log --pretty=raw Output: commit 9fceb02b21337d3025f69e22f68c82d20a000000 tree 36b74b3b8f6a... parent cf23df2207d9... author John Doe committer John Doe Commit SHA-1: Fingerprint of the current state.

    Git as a Content Manager: Beyond Version Control
    Unlocking Git’s Inner Mechanics for Expert-Level Mastery When most developers think of Git, version control comes to mind. But beneath its porcelain surface lies a powerful, content-addressable file system designed with immutability, integrity, and efficiency in mind. This post peels back the layers to explore Git as a content management system, powered by cryptographic hashing and a robust object model. At the core of Git is content-addressability—a paradigm where content is identified and retrieved using a SHA-1 hash, not a filename. “If two pieces of content are the same, Git ensures they are stored once—immutably and efficiently.” This design guarantees: Uniqueness: Identical content results in identical hashes. Integrity: Any mutation alters the hash and creates a new object. Dedupl…  ( 5 min )
    How to Maintain Content Editable Box Functionality with Color Change
    In modern web development, creating a dynamic user interface with interactive elements is crucial. One common use case is the contenteditable attribute, which allows users to edit text directly in a block element. In this article, we'll address a specific challenge: how to change the color of certain characters while still allowing users to type freely in a contenteditable div. Understanding the Problem The issue arises from the way you are manipulating the inner HTML of the contenteditable div. When you use innerHTML to replace characters with styled elements, it effectively refreshes the entire content of the div, causing the cursor position to reset and leading to a frustrating user experience. This can also prevent users from typing, as they may lose their current input context.…  ( 4 min )
    The Perils of "I'll Fix That Later": A Smart Home Sob Story
    You know the drill. That tiny, deceptively benign issue you've been studiously ignoring, muttering "Eh, I'll fix that later."

    How Do ACID Principles Work in SQL Databases?
    In the world of databases, ensuring data integrity and consistency is paramount. This is where ACID principles come into play. ACID stands for Atomicity, Consistency, Isolation, and Durability, and these principles are foundational to any SQL database operation. Let's explore each principle and provide examples to illustrate how they work in practice. What Are the ACID Principles? Atomicity Atomicity ensures that a series of database operations either fully complete or do not happen at all. This means that if one operation in the transaction fails, all previous operations are rolled back to maintain the state before the transaction began. For example, consider a banking application where we need to transfer funds from one account to another. Both deduction from the sender's account and add…  ( 5 min )
    Why does operator+= work with initializer lists in C++?

    What I Learned During the SheFi Program — And Why I Recommend It
    What I Learned During the SheFi Program — And Why I Recommend It I started my journey into the world of crypto with a lot of doubts. I thought: "If anything, I’d invest in ETH, not Bitcoin." But even then, I was concerned about the environmental impact. Reading more, I discovered that Ethereum had transitioned to a more sustainable consensus mechanism — Proof of Stake (PoS) — unlike Bitcoin's Proof of Work (PoW). That helped ease my conscience a bit. But that was just the first hurdle. I set up my wallet and opened an account on a crypto exchange.

    Creating Dynamic Routes in Next.js with Just 4 Lines of Code
    Did you know you can create dynamic routes in Next.js with just four lines of code? As a freelancer working on front-end projects to pay the bills (thanks, American healthcare system), I recently discovered how to create dynamic routes in Next.js without any extra complications. The Problem I was tasked with creating a list of dashboards for Annual Performance Reviews (APR). Each APR has a unique name, and each one needs its own route, like: http://localhost:3000/apr/[ReviewType] With a large dataset containing various types of APRs, manually creating each route by making individual folders inside the app directory wasn’t feasible: -- app Manually replacing review[index].type with the actual review types from my data would be tedious and inefficient. The Solution I simplified the structure by creating a single folder: -- app Using square brackets in a folder name creates what Next.js calls a Dynamic Segment. With a Dynamic Segment, you can access all the parameters using the useRouter hook. In my case, I didn’t need to use the hook because I already had the review types, and the slugs in the URL matched those types. The solution was straightforward: const reviewType = reviewsType.find((rt) => rt.slug === params.reviewType); The {params} are the props in the page.jsx file of my Dynamic Route. If the reviewType from the URL matches the slug type, it’s a valid reviewType, and I can create the slug. It’s that simple. Later, I'll call the Links with their href destination to generate the user’s click in the sidebar component: reviewsType.map((rt) => {rt.title} ); Conclusion Next.js routing is incredibly powerful and easy to use. I’m excited to continue exploring all of Next.js’s capabilities and preparing a course for developers like me.

    $100K/day cloud bill isn't a Bug – it's by Design
    Cloud platforms are built to scale. That’s their core feature — and their hidden risk. Every request to a cloud function, database, or storage API has a cost. If enough requests arrive, even legitimate-looking ones, the backend will scale automatically and incur that cost — and the account owner will receive the bill. This is not an exception. It is the intended behavior. Several public cases illustrate how cloud billing can be exploited or spiral out of control: $100K in 24 hours via Firebase – A WebGL hosting app saw a sudden traffic spike and was billed over $100,000. The cloud service scaled perfectly. No failure occurred — other than financial. One public file in Firebase = $98K – A single shared file led to massive egress usage and a near six-figure bill. GCP DDoS → $100K+ pro…  ( 4 min )

    React Full-Stack Just Code: Build a Business 🧠💰
    If you're a React developer, you've probably built dozens of projects. Maybe a weather app here, a dashboard there, or even a clone of some Silicon Valley unicorn. But here's a blunt truth: 🚨 Most devs are rich in code and poor in strategy. In this post, we're flipping that script. I’ll show you how to go from a React builder to a React business — using skills you already have, without waiting for VC funding, cofounders, or "the perfect idea." Let’s build something that pays you back. React devs often forget we hold superpowers: We can prototype ideas in hours. We know APIs and how to stitch products together.

    Effective Patterns for Shared State Management in React
    As React applications scale, managing shared state across components becomes one of the trickiest challenges. Choosing the right state management pattern can drastically impact maintainability, performance, and developer experience. Whether you're building a small dashboard or a sprawling enterprise SPA, this guide walks through modern and effective shared state management patterns in React. Before introducing tools like Redux or Zustand, ask: Is this state needed by many components? Does it need to persist across navigation? Should it be cached, memoized, or reactive? If the answer is no, local state via useState or useReducer is usually enough: const [isOpen, setIsOpen] = useState(false); Premature global state can overcomplicate things. React’s built-in Context is perfect for theming, …  ( 5 min )
    How to Dynamically Filter Pandas DataFrame by Date in Python?
    Introduction When working with data in Python, especially using the Pandas library, you often need to filter DataFrames based on specific conditions—like dates in your case. However, dynamically generating filter conditions can sometimes be tricky. If you've noticed that your dynamically created filter condition is yielding an empty DataFrame, don’t worry; you’re not alone in this struggle. Let's break down your issue and solve it step by step! Understanding the Dynamic Filtering Issue The issue arises from logical operations in your loop. When you create a filter condition dynamically, you must ensure that the logical operators are applied correctly. In your case, using & for element-wise AND operation is correct; however, the parentheses and precedence in evaluating the filter might be c…  ( 4 min )

    Recurring Calendar Events in Rails
    This article was originally published on Rails Designer Last week I released v1.14 of Rails Designer's UI Components. With that release came a fully-customizable Calendar Component, built with ViewComponent and designed with Tailwind CSS. Since that release I got two times the question via email about recurring events. Does that work? And indeed it does. The Calendar Component simply accepts an events array/collection. And while this kind of functionality is out-of-scope of a UI component (and the support for it), I am currently working on something that just happens to need this kind of feature. It is not at all too difficult to start (the tricky bits start when hundreds of thousands of events are created 😬). So what else can I do then to share how I would approach this in an article?

    Optimizing Vue.js for Maintainability in Mid-to-Large Codebases
    As Vue.js applications scale, code organization becomes just as important as functionality. What starts as a couple of Vue components can easily evolve into a hundred interconnected files, each with their own state logic, side effects, and styling concerns. To prevent tech debt and burnout, let’s talk about how to design Vue.js projects for maintainability. A well-organized src/ directory can make or break a large Vue application. The common pitfall is stuffing everything into a components/ folder. Instead, group files by domain or feature: src/ ├── modules/ │ ├── auth/ │ │ ├── components/ │ │ ├── views/ │ │ └── store.js │ └── dashboard/ │ ├── components/ │ ├── views/ │ └── store.js ├── shared/ │ ├── components/ │ └── utils/ This approach aligns with …  ( 4 min )
    Angular & Facades: So entkoppelst du deine Components und machst deinen Code wartbarer
    Sobald eine Angular-Anwendung wächst kann es schnell unübersichtlich werden. Komponenten die beispielsweise direkt auf Backend-APIs zugreifen oder den Application-State manipulieren sind hier aus meiner Erfahrung heraus keine Seltenheit und führen langfristig zu Problemen. Komponenten werden zu groß, die Testbarkeit leidet und das Austauschen von Stores oder APIs wird mühsam und kostspielig. Ein Lösungsansatz für diese Problematik könnte die Verwendung von Facades sein. Facades sind eine Art von Design-Pattern, das eine vereinfachte Schnittstelle zu einer komplexen API oder einem System bereitstellt. In Angular-Anwendungen können Facades verwendet werden, um den Zugriff auf verschiedene Teile der Anwendung zu abstrahieren und zu vereinheitlichen.

    Avoiding Common Eloquent Pitfalls in Laravel Projects at Scale
    When you're working with Laravel at scale, Eloquent — Laravel's beloved ORM — can be a double-edged sword. It’s expressive and elegant, but it can lead to subtle and costly performance issues if not used with caution. Over the years, I’ve worked on large Laravel applications where data integrity, response time, and system load were mission-critical. This post explores the common pitfalls I’ve encountered with Eloquent and how to avoid them. The N+1 Query Problem One of the most infamous issues is the N+1 query problem. If you've ever looped through a collection and accessed a relationship inside the loop, you’ve likely caused this. For example: $users = User::all(); foreach ($users as $user) { This results in 1 query to fetch users, and 1 query per user to fetch the profile — causing pote…  ( 4 min )

    How I Lost 35kg and Built a Habit Tracker That Actually Works
    How I Lost 35kg and Built a Habit Tracker That Actually Works Six months ago, I was lazy, unfocused, and overwhelmed. I’d scroll mindlessly on my phone, work beyond healthy hours, skip workouts, and constantly put off things I knew were good for me. I didn’t need a fancy productivity system — I needed a push. Something simple. Visual. Relentless. That’s when I built Days Without – Habit Tracker. I wasn’t aiming to reinvent productivity apps. I built Days Without for myself — because I genuinely needed help. I was tired of breaking promises to myself like “I’ll start tomorrow” or “just 10 more minutes on Instagram.” I needed a streak counter. A clear, visual reminder of how long I’ve stuck to something. Something lightweight and shame-free, but still motivating. With Days Without, I start…  ( 4 min )

    This is a submission for the Amazon Q Developer "Quack The Code" Challenge: Exploring the Possibilities This project tries to make technology accessible to many more people. Today, a lot of developers are good in programming & technology but not many are proficient in English. This becomes a barrier for them to use technology. Using Amazon Q Developer, I have demonstrated a simple use of Amazon Q to generate documentation in regional languages like Hindi. Having documentation in familiar, non-English, local languages will make technology accessible to many more people, thus becoming more inclusive. Adoption of Amazon Q will also increase. https://drive.google.com/file/d/1zXTwx5VzkeTugUMlDAibUfVV4MLsWdkw/view?usp=sharing https://github.com/msr2610/neometroapi Here is how I used Amazon Q Developer: Open new chat in Amazon Q Developer Give a new "/dev" command and provide following prompt: a) From Java code file (Neocontroller.java), pick up all routes After this, Amazon Q Developer correctly generates a markdown file with description for each route in Hindi.

    How to Set Default Template Parameters in C++ for Templates?
    In C++, template programming allows for great flexibility by enabling developers to write generic and reusable code. One common requirement is the need to specify default template parameters when using template templates. If you have a function that utilizes a template template parameter, you may want to provide default types for those parameters, particularly when dealing with standard containers like std::unordered_map. Understanding Template Template Parameters Before we dive into the solution, let’s clarify what template template parameters are. A template template parameter is a template that takes other templates as parameters.

    Leetcode - 124. Binary Tree Maximum Path Sum
    When working with binary trees, it's common to process each node with post-order traversal (left → right → root). But when the goal is to find the maximum sum of any path, including those that may start and end at any node, we need a careful approach to handle different types of path combinations. The main idea is to use depth-first search (DFS) and, at each node, calculate: The best path that can be used to extend to the parent (choose either left or right subtree). The best complete path that can split at the current node (includes both left and right subtrees). We track a global variable res to store the maximum sum seen so far. Here’s the breakdown: For each node, recursively calculate the maximum sum path from the left and right subtrees. If a child path gives a negative sum, ignore i…  ( 8 min )
    Bungie has motion to dismiss Destiny 2 copyright lawsuit denied over 'vaulted' campaign storyline
    TL;DR: Bungie’s bid to toss out a Destiny 2 copyright lawsuit got shot down by the Eastern District of Louisiana. The dispute centers on two “vaulted” campaigns—The Red War and Curse of Osiris—that plaintiff Matthew Kelsey Martineau says lifted key character and faction details from his 2013–14 WordPress posts. Bungie tried to use gameplay videos, wiki pages and an affidavit (since the original code no longer runs) as “accurate reproductions,” but the court refused to treat third-party materials as a substitute for side-by-side comparison. With no way to show the vault-deleted content, the motion to dismiss was denied and Martineau’s infringement claims move forward.  ( 3 min )

    Method Binding in NestJS: What It Is and When to Use It
    In NestJS development—a Node.js framework focused on modular architecture and class-based design—one concept that can confuse developers is method binding. This blog post explains what it is, when it matters, and how to handle it properly. In JavaScript and TypeScript, the value of this inside a method can change depending on how and where the method is called. Method binding refers to ensuring that this inside the method always points to the correct class instance, especially when the method is passed as a callback. setInterval @Injectable() export class MyService { private count = 0; increment() { this.count++; console.log('Count:', this.count); } start() { setInterval(this.increment, 1000); // 'this' is undefined here } } In this example, this.increment lo…  ( 3 min )
    Newborns living near trees tend to be healthier and new data suggests it’s not because healthier people reside near parks
    TL;DR: A Drexel University study dug into data from Portland, Oregon—tracking over 36,000 trees planted between 1990–2020—and found that mothers living within 100 meters of newly planted trees tend to have heavier, healthier babies. After controlling for factors like income, education and BMI, researchers saw each new tree bump birthweight by about 2.3 grams; hanging out near ten or more trees equated to a roughly 50-gram gain, plus lower risks of pre-term and small-for-gestational-age births. What’s cool is that this goes beyond just big old parks: even new saplings make a difference, hinting that planting trees is a simple, low-cost public-health win. Established trees also helped buffer road-density effects (think less noise and pollution), and the team thinks part of the benefit comes from the stress-busting “soft fascination” of green surroundings. The authors call for randomized trials, but treating tree-planting as a natural experiment already makes a strong case that more greenery = healthier starts to life.  ( 3 min )

    Why is msgget() throwing 'No such file or directory' in IPC?
    Understanding the Error with Message Queues in IPC Inter-Process Communication (IPC) is a key aspect of programming that facilitates communication between different processes. One common method for IPC is using message queues, which allow processes to send and receive messages in a structured way. However, as you dive into IPC programming, you may encounter errors such as msgget() returning No such file or directory. In this article, we will explore why this error occurs and how to resolve it. What Causes the Error? Before we delve into the solution, it’s crucial to understand the source of the error.

    Does Ruby Support Tail Call Optimization (TCO) in Functional Programming?
    In functional programming, recursion is a fundamental concept often utilized to solve various problems. This leads us to the discussion of Tail Call Optimization (TCO). This optimization allows a function to call another function, or itself, without requiring a new stack frame, effectively reducing overhead and memory usage. While many functional languages utilize TCO to enhance performance, it raises an important question: does Ruby implement tail call optimization? Understanding Tail Call Optimization (TCO) TCO is key in functional programming for several reasons. When a function calls another or itself as its last action, traditional languages allocate a new stack frame for each call, which can lead to stack overflow or excessive memory use. TCO allows the programming language to reuse …  ( 4 min )

    Why I Ditched Apple Remote Desktop: A DevOps Engineer's Journey to Smarter Mac Management
    Intro: Apple Remote Desktop (ARD) might've been cool in 2010. But today, it feels like managing a modern Mac environment with a rotary phone. No logging, no alerts, clunky performance, and good luck if your team’s outside your local network. I hit a breaking point as a DevOps engineer supporting hybrid teams using Macs for testing and builds. I needed real-time access, reliable performance, and automation hooks. So I did what most of us do when we’re fed up—I built a workaround, failed at it, and then finally found a smarter way. ARD is stuck in the past. It assumes you're on the same network. It’s slow over VPN, doesn’t scale, and worst of all—it asks for manual approvals and fails silently when permissions aren’t set right.

    SpiderJS 🕷 | JS Runtime Revealed: The Three Pillars of JavaScript Execution
    JavaScript (JS) started in browsers with Netscape, but its flexibility has spread it to servers (Node.js, Deno, Bun), mobile apps (React Native, Ionic), and desktop apps (Electron). Each environment needs a setup to run JS code and convert it to machine instructions. This setup is the JavaScript Runtime Environment. Here, we’ll explore what it is and its core components, preparing for a deeper look at JS execution in future articles. A runtime environment is the system that lets JavaScript code run and interact with its platform. It centers on a JavaScript engine, which parses, compiles, and executes code, turning JS into bytecode or machine code, often via Just-In-Time (JIT) compilation (more on that later!). But the engine isn’t enough. JS is single-threaded, handling one task at a time.…  ( 4 min )

    Llambda.co — Serverless AI made simple
    The Current Landscape 🌐 The traditional inference model, pioneered by companies like OpenAI, revolves around providers offering one or a few large language models (LLMs) with 100% uptime and swift responses. This approach simplifies GPU management since all users share the same LLM, ensuring even load distribution. However, this convenience comes at a cost: Users are typically charged based on arbitrary, non-transparent metrics like token count. The selection of LLMs is sparse, they are usually censored and your data is being trained on. 😕 An alternative is the serverless model, where you rent a GPU instance and install any LLM you want with specialization and features tailored to your needs. This approach offers: Transparency: Pay only for actual GPU usage. Flexibility: Choose from th…  ( 4 min )

    Getting my feet wet with Crossplane
    In the early days of IT, we manually configured servers–each one a precious snowflake, lovingly maintained and documented. But the size of the infrastructure grew and this approach couldn't scale. Chef and Puppet popularized the idea of Infrastructure-as-Code: engineers would define the state of the machine(s) in text files, stored in Git–hence the name. A global node would read these files to create a registry. Then, a local agent on each machine would check the desired state at regular intervals, and reconcile the current state with the registry. The first generation of IaC managed the state of existing machines but assumed the machine was already there. The migration to the Cloud created another issue: how do you create the machine in the first place? Another IaC tool appeared in the fo…  ( 7 min )

    Why Upwork Isn’t Enough Anymore. And That’s Okay
    I used to think I just needed to send more proposals. Boost the right gigs. Optimize my profile. But over time, I realized something deeper was off, not just with the platform, but with the entire freelance ecosystem. If you go to Upwork, at first, it looks like jobs are popping up all the time. Feels like opportunity, right? But most of these jobs are low-paying, low-quality, or outright spammy. It's getting disheartening. During the pandemic, I managed to land some gigs after just a couple of proposals (and I was a total noob who had just graduated). I even got a long-term client without having to pay a cent.

    How to Calculate Current Onhand Inventory in Oracle SQL?
    Introduction Calculating inventory levels in SQL can be tricky, especially when you need to derive values based on previous rows. In your case, we want to compute a new column, Avail_to_fill, which will be the difference between the Onhand quantity and the Qty ordered for each item. This calculation should depend on the preceding row's result. Understanding the Problem The table you provided has several columns: ORDER#, Date, Item, Qty, Onhand, and Avl Fill. The requirement here is to create a new column that shows the available inventory (Onhand minus Qty) line by line and restarts the calculation whenever a new Item is encountered. This behavior can be achieved using Oracle SQL's analytic functions and a common table expression (CTE) for structured queries. This technique incorporates th…  ( 4 min )
    How to Start with Database Migrations
    If you're adjusting your schema or moving platforms, you're doing database migration. Whether small or large, migrations help keep your app in sync with changing requirements. This post gives you practical examples and a walkthrough of tools that simplify the process. 1.Schema Migration Change structure to support new features. Example: ALTER TABLE users ADD COLUMN last_login TIMESTAMP; Use tools like Flyway or Django ORM to track these in code. 2.Data Migration Needed when changing storage engines, consolidating databases, or upgrading versions. Example: INSERT INTO new_customers SELECT * FROM legacy_customers; Run these in batches or use a managed service for large datasets. Add indexes for speed Create constraints for safety Normalize tables for better structure Example: CREATE INDEX idx_user_email ON users(email); Flyway: Write raw SQL, versioned Liquibase: Use XML/JSON changelogs Django: Auto-migrations with Python models AWS/GCP DMS: Ideal for cloud-native migrations Updating your schema, moving data, or shifting databases entirely. Define scope, create backups, test in staging, automate changes. Not for every change, but yes for version control, rollback, and CI/CD pipelines. Loss of data integrity, broken constraints, or downtime. Avoid with dry runs and monitoring. Migrations are part of growing your application the right way. Whether adjusting models or moving cloud platforms, a structured approach with the right tools keeps your data safe. Want to discover more about data migration?

    How Code Signing Improves User Trust and Download Rates
    In today's digital landscape, software developers face a significant challenge: convincing users that their applications are safe to download and use. As cybersecurity threats continue to evolve, users have become increasingly cautious about what they install on their devices. This is where code signing emerges as a crucial practice for developers looking to build trust and increase download rates. Code signing is a security practice that involves applying a digital signature to software or executable files.

    Shadow APIs: Understanding the Risk and 6 Ways to Reduce It
    What Is a Shadow API? A shadow API is an application programming interface that is created or used without explicit approval from the organization’s IT or security teams. Shadow APIs can emerge from various sources, including developers experimenting with new features, legacy systems that are no longer officially supported but still in use, or services integrated outside of formal IT channels. This is part of a series of articles about API security Unlike official APIs, shadow APIs lack oversight and governance, making them invisible to the security measures typically applied to known and documented APIs. They operate under the radar of standard security and monitoring practices. Because these APIs were not introduced through sanctioned processes, they are excluded from inventory or documentation efforts. As a result, shadow APIs present significant risks. They are not subjected to regular security assessments, patches, and compliance checks that would normally be part of an API’s lifecycle management in a secure software development environment.

    Azure Monitor Telemetry Client — Reinvented
    Recently, I was brought on board of yet another project to help build an enterprise-grade IT solution based on Microsoft Power Platform and Azure. Like any well-architected system, the solution required robust observability — the ability to track operational behavior, diagnose issues, and maintain visibility across all components. Naturally, Azure Monitor was the go-to choice. One of the core components of the solution was a custom plugin for Power Platform. To capture application-level telemetry from the plugin, the obvious approach was to use a telemetry client that integrates with Azure Application Insights, a feature of Azure Monitor. By default, Application Insights allows unauthenticated data ingestion — which makes it a potential target for abuse. To address this, the instance was c…  ( 6 min )

    How to Retrieve Selected Index from Gtk DropDown in Rust?
    In Rust, when using GTK's DropDown widget, you may want to execute a closure to retrieve the selected index upon the selection change. A common issue developers face is accessing the selected choice directly from the ParamSpec. Let's dive into how to do this effectively. Understanding the DropDown and Connect Closure When you create a DropDown in GTK, you define the choices it contains. In your example, you have created a DropDown with two options: let choix = ["Choice 1","Choice 2"]; let drop_down2 = gtk::DropDown::from_strings(&choix); Here, choix is an array containing the two options. The DropDown will display these choices in the user interface. To respond to user interaction, you set up a closure that will be executed whenever the selected choice changes. The…  ( 4 min )
    Visual Studio Code: The Unexpected Bridge Between Worlds
    In the vast universe of software development, Visual Studio Code has emerged as a key tool—an unexpected bridge connecting worlds that once seemed incompatible. It has become a lifeline for developers coming from the GNU/Linux ecosystem, desperately seeking a way to write desktop applications, something they thought was lost in their environment. Its versatility allows for development in C#, C++, and FPC Pascal, avoiding alternatives like Lazarus, and offering a more modern and robust option. Personally, I’ve found myself using it as an alternative to Visual Studio 2022, since developing a .NET 6, 7, or 8 application on Linux is financially more viable for my business than doing so on Windows. But here’s the question: Why does Visual Studio Code feel like an orphaned and underappreciated sibling compared to Visual Studio 2022? Both serve incredible purposes. Visual Studio 2022 is the enterprise-grade powerhouse, while VS Code is the agile alternative—the gateway for many developers coming from GNU/Linux, looking to explore Windows and its tools, or simply wanting to use .NET Core on Linux. That in itself is a massive achievement, a step forward in software evolution. Because in the end, bluntly speaking, Linux is great... but if it doesn’t pay the bills, what can I do? As developers, we need to produce high-quality software using high-quality tools. That’s why Visual Studio Code becomes the logical and efficient choice—a path that allows us to keep programming in diverse environments while maintaining productivity and financial sustainability. Ultimately, VS Code isn’t just a code editor… it’s the bridge that unites worlds that once seemed irreconcilable.  ( 3 min )
    VC写Windows服务程序
    之前写的后台的控制程序,我采用的都是用VC或者是C#写完之后然后采用AlwaysUp或者是nssm把自己写的后台程序再给做成一个Windows的服务程序。但后来想了想为什么不自己直接写一个Windows的服务程序呢。所以就开始了写服务程序的历程。 首先大致的说一下C#语言写一个Windwos服务程序的方法。说实话C#想写一个Windows服务程序相对的要简单的多。因为C#已经都给准备好了。就在创建项目的选择Windows服务项目就可以了。然后再添加一个服务安装的组件,改一下相关的配置,如:服务名、启动类型、启动权限或者叫启动时的用户。这些信息就可以了。在写代码的时候只要在开始的里面写上服务启动时需要做的工作,在结束里面写上服务停止时需要收尾的工作就大功告成了。 下面主要是说一下采用VC写Windows服务程序。这个我个人觉得相对来说有几个坑需要避。 第一个坑就是如果你从网上查的话都会说用VC写Windows服务程序的入口主函数是ServiceMain()这个函数。而实际并不是,实际上的程序入口还是从main()这个函数开始的。只不过在这个函数中我们不能做太多的事情,必须要尽快的调用StartServiceCtrlDispatcher()这函数来启动ServiceMain()函数。而且ServiceMain()这个函数的名字也并不一定就是这个,可以自定义。只不过你在网上查的人都会采用这个函数名而已。并非VC语言的规定或者约束。这个函数也只不过是在调用StartServiceCtrlDispatcher()函数的时候的一个参数而已叫什么名字并不重要。 第二坑就是服务状态的变换问题,只有你有ServiceMain()函数中调用了SetServiceStatus()函数来告诉Windows操作系统你的服务程序是开始启动了还时正在运行之中还是正在停止之中才可以。在这方面我从网上查了好长时间没有一个写的清楚的。我开始的时候以为这个函数没什么大用于是把相关的代码给删掉了,结果就会发生服务程序的状态无法改变。比如你在启动服务的时候没有及时的状态改成正在运行的话那么Windows的服务控制台就会一直启动这个服务直到启动超时而报错最后服务的状态就会卡在启动状态无法将服务停止或者删除。如果你能将服务状态进入到正在运行状态,但在发出停止服务的时候如果不能将服务的状修改成停止的话那么Windows也会一直停止这个服务直到停止超时而报错。而且这个服务的状态也会卡在停止的状态无法改变。 第三个坑就是在ServiceMain()函数中在用SetServiceStatus()函数把服务的状态修改成“正在运行”的状态之后必须要调用WaitForSingleObject()函数把这个服务的主线程给卡住然就是是一直等待发出服务停止的信号。所以在真正的主线程中你是无法再做其它的任何的工作的。故如果要想写好一个完整的Windwos服务程序就必须在ServiceMain()函数调用WaitForSingleObject()函数之前将你想做的事情都给加载完毕之后再调用WaitForSingleObject()函数将主线程卡住一直等待停止服务的指令。当停止服务的指令来临的时候再调用SetServiceStatus()函数把服务的状态修改成已经停止。 第四个这个不算是坑了这个算是一个常识。就是服务程序的调试问题。如果想调试Windows服务程序那么就只能采用“附加到进程”的方式。即先从Windows的服务管理器中启动服务,然后从Visual Studio的“调试”菜单中选择“附加到进程”的选项然后再选择自己程序的那个进程就可以了。 总结一下,那就是不论是VC写Windows服务程序还是C#写Windwos服务程序,都会有一个开始服务的初始化函数。而初始化函数中不能有死循环,但一般的服务程序又必须要用死循环,所以一个完整的Windwos服务程序一定是一个多线程的,在初始化的时候就启动其它的想要加载的死循环的线程。还会有一个程序的销毁函数,同样在销毁函数中也不能有无法完成的循环。最后就是Windwos服务程序的调试必须采用附加到进程的方式来进行。  ( 2 min )

    DAY 40: Array in Looping JAVA
    In Java, an array is a data structure that stores a fixed-size, sequential collection of elements of the same data type. It is a container object that holds a fixed number of values of a single type. The length of an array is established when the array is created and remains fixed throughout its lifetime. Arrays are used to organize data efficiently and can be defined and initialized in various ways. Array - Group of similar datatypes Why do you use an array? Arrays are handy when you want to work with multiple values of the same data type. Instead of declaring individual variables for each value, you can group them together in an array, making your code more concise and easier to manage.

    Former FTX exec's wife says gov't 'induced a guilty plea'
    Michelle Bond, the wife of former FTX Digital Markets co-CEO Ryan Salame, who faces federal campaign finance charges, is pushing for dismissal on the grounds that US prosecutors deceived her husband in a plea deal. In a May 7 filing in the US District Court for the Southern District of New York, Bond’s lawyers reiterated some of the claims Salame made in opposing his plea deal with the government, which ultimately still led to him serving time in prison. She claimed that prosecutors obtained a deal with Salame through “stealth and deception” by allegedly agreeing they would not file charges against Bond.  “Mr. Salame and Ms. Bond’s attorneys were advised that the agreement to cease investigating Ms. Bond could not be placed within the four corners of the Salame plea or other written agreem…
    Mashinsky’s 12-year sentence sets tone of enforcement in Trump era
    The US federal court for the Southern District of New York has sentenced former Celsius CEO Alex Mashinsky to 12 years in prison for fraud. Mashinsky’s legal team sought a light sentence. They highlighted his spotless record before the Celsius incident, along with his military service and willingness to plead guilty. But US prosecutors were less inclined to leniency, suggesting on April 28 that the judge deliver a 20-year sentence for his actions.

    US Stablecoin bill blocked as Democrats withdraw support
    The Guiding and Establishing National Innovation for US Stablecoins of 2025 Act, known as the GENIUS Act, failed to pass cloture in the United States Senate on May 8, dealing a slight blow to cryptocurrency regulation in the country. The bill, sponsored by Senator Bill Hagerty and co-sponsored by Senators Tim Scott, Kirsten Gillibrand, Cynthia Lummis and Angela Alsobrooks, received last-minute pushback from Democrats, who took aim at the bill and raised concerns about US President Donald Trump’s cryptocurrency ventures. To address the concerns of Senate Democrats, the bill had already been amended to include stricter requirements for stablecoin issuers for further provisions for Anti-Money Laundering. The GENIUS Act was seen as a bipartisan effort to increase regulatory clarity for digital assets in the United States. The focus of the bill, stablecoins used for payments, was looked at as extending dollar dominance internationally and straying away from more controversial crypto topics. After the procedure failed, Senate Majority Leader John Thune criticized Democrats, saying, “Democrats have been accommodated every step of the way […] frankly, I just don’t get it.” This is a developing story, and further information will be added as it becomes available.
    Trump tricked into pushing XRP for crypto reserve: Report
    US President Donald Trump was reportedly manipulated by a lobbyist tied to Ripple Labs into announcing the XRP token would be part of his plans for a national cryptocurrency reserve. According to a May 8 Politico report, an employee of pro-Trump lobbyist Brian Ballard gave the president the text to a social media post she recommended he write announcing a US strategic crypto reserve that would include XRP, Solana (SOL), and Cardano (ADA). After he posted the message to his social media platform on March 2, Trump learned Ripple was one of Ballard’s clients, infuriating the president, who felt like he’d been used, Politico reported, citing two people familiar with the incident. “He is not welcome in anything anymore,” said Trump, referencing Ballard, according to the report.

    SEC considers new rules easing security token issuance
    The US Securities and Exchange Commission (SEC) is considering rule changes to let companies more freely issue tokenized securities, SEC Commissioner Hester Peirce said in a speech published on May 8. The regulator is “considering a potential exemptive order” for firms using blockchain technology to “issue, trade, and settle securities” that would release them from certain registration requirements, Peirce said in the speech. For example, decentralized exchanges (DEXs) may no longer need to register “as a broker-dealer, clearing agency, or an exchange,” Peirce said. The SEC has previously brought numerous charges against DEXs such as Uniswap for failing to register as securities exchanges. Firms should “not have to comply with inapt regulations, which, in many cases, were developed well b…
    Are layer 2s good for Ethereum, or are they ‘extractive?’
    Layer 2s have been a great blockchain success story. They’ve reduced congestion on the Ethereum mainnet, driving down gas fees while preserving security. But maybe they’ve become too successful, drawing chain activity and fee income from the parent that spawned them? At least that’s what some are suggesting lately, most recently at Cornell Tech’s blockchain conference in late April. Indeed, some think Ethereum should be a little greedier, or at least fight harder for a bigger part of the revenue pie, particularly sequencing fees.  “People in the Ethereum Foundation [the nonprofit that supports the Ethereum ecosystem] will tell you that, ‘Yes, we effed up by being too ivory tower.’ I have heard that multiple times,” said David Hoffman, an owner at Bankless, during a panel discussion at the …

    Ex-Celsius CEO asks to travel for a wedding after sentencing
    Former Celsius CEO Alex Mashinsky will probably be allowed to travel for his daughter’s wedding regardless of the outcome of his May 8 sentencing hearing. In a May 8 filing in the US District Court for the Southern District of New York, Judge John Koeltl approved an application for Mashinsky to travel from New York to Memphis, Tennessee, between May 26 and May 29 for his daughter’s wedding. The approval was available on the public docket on May 8, but later appeared to have been removed. Judge Koeltl will determine in a May 8 hearing whether Mashinsky serves prison time following a plea deal with prosecutors. The former Celsius CEO appeared ready to go to trial in 2024 until his lawyers lost a motion to have his charges dismissed. He pleaded guilty to commodities fraud and a fraudulent scheme to manipulate the price of the platform’s native token, CEL. Mashinsky has been free on a $40-million bond since July 2023, with travel outside certain areas requiring court approval, such as the roughly 900-mile (1,500-kilometer) distance between New York and Memphis. As of May 8, it’s unclear if he will be expected to surrender to authorities.

    User experience could be crypto’s superpower—or its kryptonite
    Opinion by Jonathan Farnell, CEO of Freedx It’s 2025, and over 560 million people worldwide are already using cryptocurrency — roughly 17 times the population of Tokyo. That’s a vibrant community, yet for every user who’s embraced it, billions more stand on the sidelines, put off by the complicated interactions and clunky interfaces of protocols, platforms, decentralized apps (DApps), and mobile applications. Why? Blockchain technology offers game-changing potential — decentralized ownership, secure trades — but let’s face it: Most people still find it intimidating, risky, and confusing. User experience (UX) might just be the deciding factor in whether cryptocurrency achieves mass adoption or remains a niche segment. Take complexity.

    Browser-based crypto mining in 2025: Still viable or virtually dead?
    Key takeaways After the shutdown of Coinhive in 2019, browser mining has made a comeback with new tools like CryptoTab Browser, Pi Network and YouHolder.

    Bitcoin DeFi sees surge in mining participation despite drop in TVL
    Smart contract platform Rootstock, the home of decentralized finance (DeFi) on Bitcoin, saw a sharp increase in network security and mining engagement in the first quarter of 2025, even as activity cooled. Merged mining participation surged to an all-time high of 81%, up from 56.4% in Q4 2024, driven by the integration of major mining pools Foundry and SpiderPool, according to Messari’s first “State of Rootstock” report for 2025, shared with Cointelegraph.

    Bitcoin returns to $98K as Fed holds rates steady despite Trump’s demand
    Bitcoin has reclaimed $98,000 for the first time in almost three months after the US Federal Reserve said it would keep interest rates the same for another month. The Fed’s decision to keep interest rates unchanged comes despite mounting pressure from US President Donald Trump, who just weeks ago threatened to fire Fed chair Jerome Powell for being “too late” in cutting rates. Fed cites higher unemployment, inflation risk Powell said on May 7 that the Federal Reserve rate-setting committee held rates in the 4.25% to 4.50% range due to the rising risks of higher unemployment and higher inflation. He added inflation has “come down a great deal but has been running above our 2% longer objective.” Powell said surveys in households and businesses showed a “sharp decline in sentiment” mainly due…

    Arizona governor signs law for state to keep unclaimed crypto
    Arizona Governor Katie Hobbs has signed a bill into law allowing the US state to keep unclaimed crypto and establish a “Bitcoin Reserve Fund” that won’t use any taxpayer money or state funds. Hobbs signed House Bill 2749 into law on May 7, which allows Arizona to claim ownership of abandoned digital assets if the owner fails to respond to communications within three years. The state’s custodians can stake the crypto to earn rewards or receive airdrops, which can then be deposited into what Arizona has called a Bitcoin and Digital Asset Reserve Fund. “This law ensures Arizona doesn’t leave value sitting on the table and puts us in a position to lead the country in how we secure, manage, and ultimately benefit from abandoned digital currency,” the bill’s sponsor, Jeff Weninger, said in a May…
    Binance founder CZ asked Trump to pardon money laundering conviction

Zhao, also known as CZ, said on a Farokh Radio podcast episode aired May 6 that he “wouldn’t mind” a pardon and that his lawyers have already filed the paperwork on his behalf “I got lawyers applying,” Zhao said, adding that he submitted the request after Bloomberg and The Wall Street Journal reported in March that he was seeking a pardon from Trump amid discussions of a business deal between the Trump family and Binance.US. Zhao denied the reports at the time, but said on the podcast that he thought “if they’re writing this article, I may as well just officially apply.” He added that Trump’s pardon of three BitMEX founde…

    Static Method
    Static method is a method bound to class and not the object of class. To define static method we will use @staticmethod decorator. Explanation: If you want somebody not to access specific function through object you can do it by applying the @staticmethod. And do not pass 'self' because it will create connection with other attribute. But if you seen closely general_description is accessible through object and class also. So the question arises does this statement defy us. Well answer is, Yes, it does. Here is analogy: You will kept your screwdriver, hammer or nickel in toolbox, so that somebody want to access it he/she will look for toolbox. If you travel through airplane doesn't which model of airplane you travel the manual of that plane will remain same like how to tie seatbelt. Same as goes for static method you just access static method function through class not by object and it doesn't defy its meaning. OOPs concept is philosophical you follow the rule so that you can have strategy how write code effectively.  ( 3 min )
    AI could do a lot more than just note-taking in meetings

    Implicit Index Access in C# 13 — Using `^` in Object Initializers
    ^ in Object Initializers The ^ operator (read as "from the end") has been part of C# since version 8, allowing developers to easily access elements from the end of collections: int last = myArray[^1]; // Last element However, until C# 13, you couldn’t use ^ inside object initializers. This restriction has now been lifted, giving developers more expressive and compact ways to initialize collections directly. Let’s explore how this change improves array initialization syntax and simplifies common patterns. Prior to C# 13: var countdown = new TimerRemaining(); countdown.buffer[^1] = 0; // Valid But you could not write: var countdown = new TimerRemaining { buffer = { [^1] = 0 } // ❌ Compiler error before C# 13 }; Now, this syntax is fully supported. ^ in Initializers public class…  ( 4 min )
    Natural Types for Method Groups in C# — Smarter Overload Resolution
    In modern C#, method groups — collections of methods with the same name but different signatures — are frequently used in scenarios like: Passing methods as delegates LINQ projections Action, Func assignments Method references in event subscriptions C# 13+ introduces an important enhancement in how the compiler handles these method groups by optimizing the resolution of a natural type (i.e., an expected delegate type) for a method group. Let’s explore what changed, how it affects overload resolution, and what it means for you as a C# expert. A method group is a set of method overloads identified by a shared name: void Log(string message) { ... } void Log(string message, LogLevel level) { ... } Calling Log without parentheses creates a method group, which the compiler tries to match to…  ( 4 min )

Also this pattern has better Accessibility out of the box. You can also write your own custom js events and handlers... Creating custom commands ```Rotate left myImg.addEventListener("command", (event) => { I'm not 100% overall on how I feel about that though, maybe it helps lower level with creating interactive elements... Maybe it feels like too little too late, time will tell.  ( 3 min )
    How to Fix 'Please provide ShowCaseView context' in Flutter?
    Introduction In Flutter, if you encounter the error message Please provide ShowCaseView context while using the ShowcaseView widget, you are not alone. I have read extensive documentation and community forums, including Stack Overflow, but still couldn't resolve this issue. This article will guide you through understanding why this happens and how to fix it effectively when integrating the showcaseview and persistent_bottom_nav_bar_v2 packages in Flutter. When you implement the ShowCaseWidget, it's essential to ensure that the context is correctly provided to the widget.

    Speech Recognition API for Voice Input
    Comprehensive Guide to Speech Recognition API for Voice Input in JavaScript Historical and Technical Context Evolution of Speech Recognition Technologies The journey of speech recognition technology started as early as the 1950s, predominantly focusing on isolated word recognition. Early systems, such as IBM's "Shoebox," recognized a mere 16 words. The evolution accelerated with the advent of hidden Markov models (HMM) in the 1980s, which allowed for continuous speech recognition. The 1990s saw the introduction of statistically based systems, leveraging vast amounts of data to improve accuracy. Fast forward to the 21st century, we witness the proliferation of deep learning techniques, particularly the use of recurrent neural networks (RNN) and convolutional neural n…  ( 6 min )

    I Didn’t Expect AI to Transform SaaS This Fast (But Here We Are)
    Not long ago, “AI in SaaS” felt like a buzzword, a chatbot here, some automation there. But in 2025, it’s clear: I recently made a quick YouTube Short that summarizes this shift in just 60 seconds. But I wanted to share a bit more context with the dev.to community, because many of us are building this future. Here’s what’s really changing: AI handles what used to be the boring, manual work, form filling, task assignment, ticket tagging, report generation. Not only is it faster, but it actually lets teams focus on solving real problems. AI isn’t just reacting anymore, it’s learning. We’re seeing apps that adjust to each user: what they click, when they drop off, which features they ignore. AI then reshapes the experience in real time. Feels like magic (but it's models). Whether it’s predicting churn, forecasting demand, or recommending next steps, smart SaaS tools are becoming proactive. This gives users (and product teams) a serious advantage. At ClickIT, we’ve been working with startups and mid-size companies to integrate this kind of AI into their SaaS platforms. It’s wild how quickly things evolve once AI becomes part of your architecture, especially when the goal is to scale fast without losing control. Here’s the video I mentioned, just 60 seconds, made to spark ideas: How AI Is Revolutionizing SaaS in 2025 Are you already integrating AI into your product? If not ❌ — What’s holding you back? And if yes ✅ — What has surprised you the most? Would love to hear how other devs, founders, and engineers here are approaching the AI shift in SaaS.  ( 3 min )

    Implementing xor value swap without third variable in C
    Swapping variables is one of the most basic procedures that are done in programming. The first approach -and usually the most used by far- is to swap using a third variable, commonly named temporal variable. I'm sure you have seen it already. void swap(int* a, int* b) { int temp = *b *b = *a *a = temp } Yeah, that's a lot of pointers for explaining a swap. Blame C, not me 😒. Either way the process is the same in all languages: The value of variable b is stored in a temporal variable The value of variable a is stored in b The value stored in the temporal variable is moved to a I don't think it is necessary to say that the same process can be done replacing a with b and b with a But what if I told you that there's a way to swap values without using extra memory for a third vari…  ( 5 min )

    What is Data Remanence?
    Data Remanence is the residual representation of digital data that remains even after attempts have been made to remove or erase the data. This residue may result from data being left intact by a nominal file deletion operation, by reformatting of storage media that does not remove data previously written to the media, or through physical properties of the storage media that allow previously written data to be recovered. Data remanence may make inadvertent disclosure of sensitive information possible should the storage media be released into an uncontrolled environment (e.g., thrown in the bin (trash) or lost). Various techniques have been developed to counter data remanence. These techniques are classified as clearing, purging/sanitizing, or destruction. Specific methods include overwriti…  ( 3 min )

    Under the hood: What can you learn by building an HTTP Server from scratch?
    Introduction: I've always been curious about how most of the technologies I use on a day-to-day basis work. One of the things we as programmers have to interact with daily is HTTP servers. Most of the time, we don't think much about it since HTTP has been around for a long time, and there are thousands of HTTP servers and clients, so most people don't give much thought to how these technologies work! As someone who worked on many web-based applications and built many restful APIs, I would like to think that I have a pretty good understanding of how the HTTP protocol works and how HTTP servers generally function, however, since I've always been using ready-made HTTP servers (Mostly Kesterl, IIS and Nginx) and HTTP clients (curl, postman, httpie) I felt that there's a lot that I can learn …  ( 14 min )

    Matrix in Python
    Problem 1: Check for a Toeplitz Matrix Problem: You are given an n x n square matrix. Write a function is_toeplitz(matrix) that checks whether the matrix is a Toeplitz matrix. A Toeplitz matrix is one where every descending diagonal from top-left to bottom-right (↘️) contains the same elements. Consider this matrix: 6 7 8 4 6 7 1 4 6 The diagonals are: [1], [4, 4], [6, 6, 6], [7, 7], [8] All elements in each diagonal are equal — so this is a Toeplitz matrix ✅. To check if a matrix is Toeplitz: Loop through each element in the matrix (excluding the last row and column). For each element, compare it with the one diagonally down-right from it. If any of those pairs don’t match, return False. If the loop completes without mismatches, return True. from typing import List def is_toeplitz(matrix: List[List[int]]) -> bool: n = len(matrix) for i in range(n): for j in range(n): if i + 1 < n and j + 1 < n: if matrix[i][j] != matrix[i + 1][j + 1]: return False return True matrix = [ [6, 7, 8], [4, 6, 7], [1, 4, 6] ] print(is_toeplitz(matrix)) # Output: True  ( 3 min )

    #7 DP: Observer
    O que é o Padrão Observer? O Observer é um padrão de projeto comportamental que define uma relação de dependência entre objetos, onde um objeto (o sujeito) notifica automaticamente outros objetos (os observadores) sempre que seu estado muda. Ele é muito útil quando várias partes do sistema precisam reagir a mudanças em um mesmo ponto. Esse padrão promove o desacoplamento entre quem emite o evento e quem reage a ele, permitindo que novos observadores sejam adicionados ou removidos em tempo de execução, sem alterar o sujeito. Em resumo, o Observer estabelece um mecanismo de notificação automática, garantindo que todos os interessados estejam atualizados sempre que algo importante acontece. As classes que devem reagir a mudanças se inscrevem no sujeito responsável por emitir essas mudanças. A classe principal recebe os observadores via o método addObserver(), registrando as implementações interessadas em ser notificadas. O método newStockData() executa a ação principal e, em seguida, notifica todos os observadores inscritos, permitindo que eles executem suas responsabilidades de forma independente. Assim caso surja uma demanda de adicionar uma nova açãoao newStockData, você não precisaria modificar a classe  ( 3 min )

    Regular Expression
    I had read about regular expressions and thought of writing a blog on this. I will try to cover as much as possible. Let's start with the basic definition. A regular expression (also “regexp”, or just “reg”) consists of a pattern and optional flags. In short, it is the method of matching strings to a pattern. Two syntaxes can be used to create a regular expression. const regexp = new RegExp("pattern","flags"); OR const regexp = /pattern/; //without flags const regexp = /pattern/flags; Regex should be written within forward-slashes /..../. These slashes play the same role as quotes in strings. The main difference between the syntaxes is that when the regular expression remains constant, use a pattern with a slash for better performance, but if the regular expression is changing, or you d…  ( 4 min )

Understanding the 'externally-managed-environment' Error This error message appears when you try to use pip to install packages, but your operating system has set restrictions on modifying the default Python environment. Essentially, your OS manages Python installations, and direct installations using pip can lead to an unstable system if packages conflict or if dependencies are missing in the system…  ( 4 min )
    Tired of JavaScript? Here is WebAssembly Tutorial!
    I know we all love JavaScript. We all love TypeScript, React, etc... But sometimes don't you feel that you want to try something else? Something new? I want to introduce a different way to build modern web apps using WebAssembly. It will bring you a next level of frontend world. Mostly, I use Rust alongside WebAssembly because it enables me to utilize a strongly static type system and efficient memory management system that JavaScript and TypeScript lack of. OK, enough, let's get to the point. First of all, to make that easy, I recommend to install Rocal which is a full-stack WASM framework to build modern web apps powered by WebAssembly. Here is a command to install it on your MacOS or Linux! $ curl -fsSL https://www.rocal.dev/install.sh | sh if you get some trouble while you are install…  ( 15 min )
    Securing Azure Networks: Creating and Configuring Network Security Groups (NSGs) and Application Security Groups (ASGs)
    This article is a continuation of Building Strong Connections: A Beginner’s Guide to Setting Up Virtual Networks and Peering in Azure. In that guide, we set up a virtual network (app-vnet) with two subnets: frontend and backend. In this article, we’ll focus on securing those subnets by implementing network security groups (NSGs) and application security groups (ASGs) to control inbound and outbound traffic between VMs and from the internet. We will deploy two Ubuntu virtual machines using an Azure Resource Manager (ARM) template provided by Microsoft. VM1 will reside in the frontend subnet, and VM2 will be placed in the backend subnet.

    How to Improve Maven Build Times for Multi-Module Java Projects?
    When it comes to building multi-module Java projects with Maven, many developers encounter longer build times that hinder efficiency. If you’re struggling with a build process that takes around 40 seconds, even with multi-threaded builds using -T and -C flags, you’re not alone. With Maven 3.2.3, optimizing build performance can seem challenging, but there are strategies to help speed things up without compromising your workflow. Understanding Maven Build Performance Maven build times can be affected by numerous factors, including: Dependency Management: The way dependencies are resolved and downloaded can impact build times. For example, if your project relies on a large number of external dependencies, Maven spends time fetching them. Build Lifecycle: The default build lifecycle consists …  ( 5 min )
    Linear Search
    Linear search is a simple algorithm that checks each element in a list sequentially until the target value is found or the list ends. Start from the first element. Compare each element with the target value. If found, return its index. If not found after checking all elements, return -1. package com.Example; break; } else { System.out.println("Not occur"); } } sc.close(); } } Time & Space Complexity Time Complexity: O(n) (Worst case: checks all elements). Space Complexity: O(1) (No extra space needed). When to Use Linear Search? ✔ Small datasets. Simple but inefficient for large datasets. Works on any list (sorted or unsorted). Easy to implement in Java. For faster searches, consider Binary Search (O(log n)) if the list is sorted. 🚀  ( 3 min )
    Reliable Redis Connections in Node.js: Lazy Loading, Retry Logic & Circuit Breakers 🔦
    If you’re using Redis in a Node.js application — especially in production — reliability isn’t optional. A bad connection strategy can lead to memory leaks, crashes, or endless retry loops. In this blog, I’ll show you how I built a resilient Redis integration in Express.js using ioredis, lazy loading, and a circuit breaker with opossum. At first, I used the classic approach: const redis = new Redis(); // 🤷‍♂️ at the top level But I quickly ran into issues: Connection errors on startup if Redis wasn’t ready. Too many retry attempts without a proper limit. No fallback strategy during Redis downtime. So, I rebuilt the entire integration with three key ideas: ✅ Lazy Loading instead of connecting at startup, I created a singleton getter that initializes Redis on first use: import Redis from "…  ( 6 min )
    Mastering Functional Programming: Immutability, Composition, Pure and Arrow Functions
    Functional programming has gained traction in modern development due to its ability to produce more predictable, modular, and testable code. In this post, we explore four fundamental principles: immutability, function composition, pure functions, and arrow functions. Immutability means that once a value is created, it cannot be changed. Instead of mutating data, we return new versions with the desired updates. ✅ Why is it useful? Prevents unpredictable side effects Easier debugging and testing Ideal for concurrent environments (like React or Redux) ❌ Mutable example: const user = { name: 'Alice', age: 25 }; user.age = 26; // Mutation ✅ Immutable example: const user = { name: 'Alice', age: 25 }; const updatedUser = { ...user, age: 26 }; // New copy with changes Function composition means …  ( 4 min )
    The Age of the Smartphone Is Ending — And Most People Haven’t Noticed
    For over 15 years, the smartphone has been the centre of our digital universe. It’s the screen we stare at, the tool we work on, the device we reach for instinctively. But look a little closer — and you’ll start to see the shift. We’re entering the post-smartphone era. Not with a bang, but through quiet disruption. And it’s already on your body. The Rise of the Wearable Web I wear a smartwatch that tracks my health, receives notifications, and lets me respond instantly. Samsung just launched a smart ring — one more layer of ambient computing wrapped around our daily lives. And of course, I can speak to an AI assistant and get intelligent, contextual responses without touching a screen. This is no longer sci-fi — this is now. A New Hub: The Invisible Puck Imagine: A tiny 5G/6G puck lives in your backpack Your glasses are your screen Your ring is your security token Your watch handles notifications and health Voice becomes your primary interface AI becomes your operating system No more swiping. No more “app folders”. No more trying to type with your thumb while walking. Screens Are Becoming Optional Even today, I can ask my glasses to play a song, call someone, or answer a question — all without touching a smartphone. I don’t need a “phone” to live connected. I just need smart inputs, wearable endpoints, and a cloud intelligence layer. What This Means App developers will have to rethink interaction: conversational, contextual, multi-device. Privacy, identity, and edge computing will take centre stage — because the phone as a walled garden will be gone. We’ll be more present — or at least, less distracted by rectangles. The Debate Begins Will we embrace ambient computing — or push back against losing physical control? One thing’s clear: the era of staring at your hand all day is giving way to something new. So here’s the question: Would you give up your phone if you could wear the web instead?  ( 4 min )
    How to Fix the 'Error when checking target' in TensorFlow.js
    When working with TensorFlow.js, it's not uncommon to encounter errors related to tensor dimensions. One such error, as you've described, occurs when the expected dimensions of your model's output do not match the shape of the provided labels (targets) during training. Let's explore this issue further and provide solutions to resolve it. Understanding the Error The error message you received states: Error when checking target: expected dense_Dense2 to have 2 dimension(s) but got array with shape 2,5,2. This indicates that the output layer of your model was expecting a different shape for its targets than what it received. In simpler terms, the model's structure is out of sync with your training data's shape. Why This Happens In your model, the last dense layer is configured to output a 5-d…  ( 5 min )

    How I Connected My Home Network with AWS Regions Using Tailscale and VPC Peering
    Hey there, fellow tech tinkerers! As a developer and cloud enthusiast, I love messing around in my home lab—a trusty Raspberry Pi 5 running my self-hosted setup. But sometimes, I need to tap into the power of AWS for testing, dev work, or hybrid projects. In this post, I’m spilling the beans on how I bridged my home network with two AWS regions (ap-south-1 and us-east-1) using Tailscale, EC2, and VPC Peering. The result? A secure, low-latency network that feels like magic. Let’s dive in! My home lab is my sandbox for coding, experimenting, and breaking things (gently).

    Thought 20250507 What is MCP
    There is a lot of noise on "MCP (Model Context Protocol)" and as someone at the forefront of technology we have no choice but to follow it up. Often, despite the initial waryneess the AI hype drains my energy, some careful study turns out to generate useful insights. MCP is a protocol, but the majority of the protocol work is already done when OpenAI annouced tool use for ChatGPT. What matters now is the standardization process of the publisher of MCP, i.e. Anthropic (Creator of Claude models and tools). In addition to the publications, MCP offers server/client implementations for C#, Python, JavaScript - and that can speed up and streamline the development process. Whenever an experienced developers sees the tool use API (e.g. from OpenAI), they will immediately think of automatic code generation and streamline and tool definition process, and develop custom tooling to define those tools and serve those tools. MCP offers a ready-to-use (language-of-your-choice) implementation for a stated server. But here is a critical observation: does MCP has anything to do with AI/LLM at all? It's reinforcing what should have already been done: making systems reflective and accessible from an outside system. Here is a pun: it requires existing systems to be more reasonable (also see Forbes article on GEO). Traditionally, when a software is developed if the original developer doesn't expose useful APIs then power users have no obvious way of automating it, except through the more hacky GUI automation route. Now with the pressure of AI, vendors have to expose useful interface. LLM with its natural language nature makes it easiser for them to pick, compared to picking a more specific scripting language (or rest API), especially when the MCP server/client framework is stated and uses JsonRPC. Also see: Medium post on "Some Reflections on MCP".  ( 3 min )
    What is TDD and BDD? Which is better?
    TDD and BDD Explained TDD = Test-Driven Development BDD = Behavior-Driven Development BDD is all about the following mindset: Do not test code. Test behavior. So it's a shift of the testing mindset. This is why in BDD, we also introduced new terms: Test suites become specifications, Test cases become scenarios, We don't test code, we verify behavior. Let's make this clear by an example. If you are not familiar with Java, look in the repo files for other languages (I've added: Java, Python, JavaScript, C#, Ruby, Go). public class UsernameValidator { public boolean isValid(String username) { if (isTooShort(username)) { return false; } if (isTooLong(username)) { return false; } if (containsIllegalChars(username)) { …  ( 6 min )

    Is the Behavior of std::byte in C++17 a Bug or Intended?
    Introduction In my journey through C++17, I stumbled upon the std::byte type and discovered some perplexing behavior that left me scratching my head. The main question is whether this behavior is intended by the C++ standards or if it's a quirk due to the compiler or operating system I am using. Understanding std::byte The std::byte type introduced in C++17 is designed to encapsulate the idea of a byte without its conventional mathematical interpretations. Unlike integers, std::byte doesn't implicitly convert to numeric types, which can lead to some interesting outcomes when performing operations with it. In the example I encountered, I defined a std::byte variable and used std::to_integer to convert it to different integer types. The Code Example Here’s the code snippet that raised my que…  ( 5 min )

    What is an HTTP Proxy?
    Ever wondered what keeps your online experience smooth, secure, and sometimes even anonymous? Meet the HTTP proxy — a powerful intermediary that stands between your device and the internet. At its core, an HTTP proxy processes and forwards your HTTP requests, essentially acting as a gateway. Instead of your browser connecting directly to a website, the proxy server does the job on your behalf, masking your IP address and offering a range of added benefits. To really grasp what an HTTP proxy does, you need to understand its building blocks. Hypertext Transfer Protocol (HTTP) is the standard protocol for transferring data online — everything from browsing websites to interacting with web applications.

    Does a Function Call End the Lifetime of Variable Length Arrays in C?
    When dealing with variable length arrays (VLAs) in C, a common concern arises regarding the lifetime of such arrays when a function call is made after their declaration. According to the C17 final draft document N2176, the lifetime of an object, including a VLA, extends from its declaration until the program execution leaves the scope of that declaration. This statement often leads to questions about whether calling a function immediately after declaring a VLA results in ending its lifetime. To clarify, let's first understand what a variable length array is and its properties. A VLA is a type of array in C where the size is determined at runtime rather than at compile-time. This feature makes VLAs quite flexible for situations where the size of data is not known until the program runs. Und…  ( 5 min )

    Binary Tree in Rust
    I am not new to rust. I have dabbled in axum, tonic, bevy and ratatui for some personal and work projects as well. Even then when someone asked me to write a Binary Search Tree(BST) in rust, I got scared. I didn't express this at the time but it kept bugging me inside. Anyway later on whenever I used to get time I used to ask AI tools to help me teach rust and write a BST specifically. I used Gemini and ChatGPT and both gave solutions as well. I could understand their code but still couldn't understand how they got there. They used Rc, RefCell etc. which I understand theoretically but never understood when and how to use it properly. After I didn't feel satisfied using AI answers I thought let me just read code. Rust actually provides a BST in standard library, you can find it here. Its ve…  ( 5 min )

    Create a simple REST application using Quarkus
    This tutorial was originally published on IBM Developer by Markus Eisele Quarkus is a Kubernetes-native Java stack tailored for GraalVM and OpenJDK HotSpot. Quarkus offers incredibly fast boot times, low RSS memory consumption, and a fantastic developer experience with features like live coding. This quick start guide gets you up and running with Quarkus on macOS, including necessary tools. You will build a basic database application using Quarkus, Java 17, PostgreSQL, and Hibernate ORM Panache. While Hibernate ORM is the standard, powerful Jakarta Persistence implementation capable of complex mappings, it doesn't always make the most common tasks trivial. Hibernate ORM with Panache is Quarkus's solution to this, focusing specifically on making your data entities and repositories simple, straightforward, and fun to write by reducing boilerplate code for common persistence operations. We'll use standard macOS tools and package managers where possible. These are the essential tools you'll need to complete this tutorial: - Podman - SDKMAN - Java 17 - Quarkus CLI - Maven Optionally, you can also install a code editor. Quarkus integrates seamlessly with containers, especially for development services like databases and other sytems. Podman is a daemonless container engine alternative to Docker. On Mac, each Podman machine is backed by a virtual machine. Once installed, the podman command can be run directly from the Unix shell in Terminal, where it remotely communicates with the podman service running in the Machine VM. It is almost transparent in usage to Docker and easy to use for development. Install Podman. Find the latest Podman release on the GitHub Release page, and download the binary for your system architecture. At the time of writing, the latest release was v5.4.1. Install either the unversal pkg installer or the arm or amd version. Continue reading on IBM Developer  ( 3 min )

    🔐 How to Secure Your AWS Lambda Functions in 2025
    AWS Lambda is a go-to service for building scalable, event-driven applications — but with great (serverless) power comes great responsibility. Here are some practical security best practices to keep your Lambda functions secure in 2025: ✅ 1. Use the Principle of Least Privilege Create dedicated IAM roles for each Lambda function. Grant only the permissions required for that function to operate. Use IAM policies with explicit allow/deny for tighter control. 🔐 2. Secure Environment Variables Instead: Use AWS Secrets Manager or SSM Parameter Store to securely manage credentials, API keys, and tokens. Access them during function runtime using IAM roles. 🌐 3. VPC Integration for Sensitive Resources Place it inside a VPC for better network isolation. Use private subnets with minimal internet exposure. Attach VPC endpoints for secure AWS service access. 📊 4. Monitor and Log Everything Amazon CloudWatch Logs for tracking function output and errors. CloudWatch Metrics to monitor: Invocation counts Duration Throttles and errors Optionally, integrate with AWS X-Ray for tracing. 📦 5. Enable Versioning and Aliases Use Lambda versioning to avoid overwriting stable code. Use aliases (like dev, prod) to route traffic between versions easily. Helps in rollbacks and gradual deployments. 🚀 Get Started Start applying these best practices today to make your AWS Lambda functions secure, resilient, and production-ready in 2025.  ( 3 min )

You might be looking for ways to implement a grid layout while ensuring that each row is visually distinct by having full row borders, rather than just borders around individual cells. In this article, we will explore how to achieve this effectively. Understanding the Grid Layout The CSS Grid Layout is a powerful tool that enables developers to create complex web layouts with ease. The problem you've encountered arises when attempting to give a clear separation between rows using borders without affecting the individual cells. Instead of applying borders to each cell, we need a different approach to make the entire row's border visibly distinct. A traditional method of creating a grid is through the use …  ( 4 min )

    Keep on Mocking with a Key, Girrrrl

Testing is a big part of Perl culture, so a skeleton module usually comes with a t/ directory to hold your tests. Once uploaded to CPAN, the CPAN Testing Service will run your tests on every OS and version of Perl possible, but you shouldn't require an active network connection on either end.

    Why I Prefer Go Over Node.js for Backend Development
    As a softwar developer, choosing the right language and tools can make a huge difference in how efficiently you build, maintain, and scale applications. While Node.js is widely adopted in the backend world, I personally prefer Go (Golang) for several key reasons. Here's why. Go is a compiled language with built-in support for concurrency through goroutines and channels. Whether it's handling multiple HTTP requests or processing data-heavy tasks, Go offers consistent and high performance with minimal memory overhead. Its lightweight concurrency model is often simpler and more efficient than JavaScript’s event loop and async/await system. Go is statically typed, which helps catch errors early during compilation. In my experience, this leads to more robust code and reduces the kind of silent …  ( 4 min )
    Delta Executor: Mobile-First Roblox Script Execution
    How We Built Delta Executor: Mobile-First Roblox Script Execution Roblox's scripting ecosystem has exploded in recent years — and so has the need for tools that empower developers to understand, test, and interact with Lua-based environments. At DeltaDevs, we created Delta Executor, a performance-first, cross-platform executor tailored for Roblox scripts on Android and iOS. Many tools in the Roblox ecosystem are outdated, unsupported, or overly complex for mobile users. Delta Executor solves that with: Script execution that’s stable across devices A secure framework with memory-safe design Keyless access for paid users (and fair key-based access for free users) Smooth compatibility across Android, iOS, and emulators for PC We built it from the ground up to handle the latest anti-cheat systems Roblox introduced in 2025. Here’s how we bypassed them. -- Delta Executor Example print("Hello from Delta Executor on Mobile!") You can load, run, and debug scripts just like this on mobile devices using our tool. Full support for popular script libraries and obfuscation is built in. While built for mobile-first use, Delta Executor also runs on Windows using emulators like BlueStacks or LDPlayer. Want to see how it works? Visit our Executor Overview Page. We're also opening up SDK access for vetted contributors and curious reverse engineers. Apply at deltadevs.net/developers We built Delta Executor with security transparency at the core. If you've seen antivirus warnings, you're not alone — many executors trigger false positives. Here's why. Official Website FAQs Script Submission Fix Guide: Executor Not Opening Delta Executor is more than an exploit tool — it’s a research sandbox for scripters, hobbyists, and curious minds working within the Roblox engine. We hope this adds value to others building tools around Lua, mobile execution environments, and anti-cheat resistance. Got thoughts? Drop your feedback or reach us via our Discord.  ( 3 min )
    When “More” Isn’t Better — A Note from a Senior Engineering Manager
    In tech, we’re wired for growth—more velocity, more releases, more impact, more headcount. But lately, I’ve been asking myself: Where does it stop? I’ve led high-performing teams, shipped at scale, climbed the ladder. But with each new role, I noticed a pattern—what looked like “success” on paper often came with hidden trade-offs: less time with family, more stress, fewer pauses to reflect. We’re told to aim for the next title, the bigger compensation package, the unicorn IPO—as if each step up will quiet the internal noise. But it doesn’t. Even at the top, many feel like they’re still chasing something just out of reach. And here’s the kicker: when wealth and power concentrate, whether in tech or society, others get squeezed. I’ve seen brilliant engineers burn out, not because they weren’t good enough—but because the system kept telling them they had to want more. But what if the real clarity doesn’t come from achieving more—but from needing less? Less chaos. I’ve found meaning in simpler things—mentoring a junior dev, walking outside between meetings, unplugging for dinner with my kids. These aren’t productivity hacks. They’re sanity savers. Because underneath the frameworks and sprint goals, we’re just part of something bigger—organic, changing, deeply human. The atoms in our bodies? They were once stars. Literally. We are nature. And like nature, we’re not meant to scale infinitely. So here’s a quiet question I’m sitting with—and maybe you should, too: 🔍 Is your pursuit of “more” giving you peace—or quietly taking it away?  ( 3 min )
    SafeLine WAF Setup: How to Handle Multiple Apps on Port 80
    📍 Problem description You have two applications: App 1 → deployed on Server A, port 80 App 2 → deployed on Server B, port 80 When you try to configure both behind SafeLine WAF, you get the error: Duplicate applications detected on port 80: * The reason for this error is: SafeLine allows only one listener on port 80 on the frontend. ⸻ ✅ How to solve it Since SafeLine currently does not support path-based routing, the only supported solution is domain-based routing. ⸻ Use different domain names (recommended) For example: App 1 → app1.example.com → Server A:80 App 2 → app2.example.com → Server B:80 In SafeLine: Configure one listener on port 80 Set routing rules based on the Host header (domain name) to forward traffic to the correct backend server. This way, SafeLine knows exactly which application the request is meant for. ⸻ ⚠️ Why you can’t use multiple port 80 listeners or path-based routing SafeLine can only bind to port 80 once on the frontend. Multiple port 80 listeners will always result in a duplicate port error. Path-based routing (/app1, /app2) is currently not supported in SafeLine. ⸻ 🚀 Summary recommendation ✅ Use different domain names and set up Host-based routing in SafeLine. ⸻ SafeLine Website: https://ly.safepoint.cloud/ShZAy9x https://github.com/chaitin/SafeLine https://discord.gg/dy3JT7dkmY  ( 3 min )
    How to quickly transform multi-layer sets in JSON strings
    There is a 2-layer JSON string with multiple dynamic key values in the lower layer, excluding set/array types. {"Games": {"key1": "value1", "key2": value2,"key3":value3}} Now we need to transform the lower layer into a set of multiple layers. {"Games":{"AllGames":[{"key1":["value1"]},{"key2":["value2"]},{"key3":["value3"]}]}} SQL itself does not support multi-layer data, making it more difficult to express multi-layer sets, and the indirectly implemented code is very complex. SPL naturally supports multi-layer data and multi-layer sets: Try.DEMO A2: Take the lower-layer data (one record), change the type to a set of records, and then transpose it to a two-layer sequence. […] represents a set, function E can convert a set of records into a two-dimensional sequence, and @ p represents transposition during conversion. new(new(…:AllGames):Games) Add two layers of record types on top of a multi-layer set to construct the target table sequence. esProc is free.

    Part 3: Mastering SafeLine WAF – Testing, Docker Setup & Troubleshooting
    Welcome to the final part of our SafeLine WAF series! So far, you have set up SafeLine and configured it for your environment. Now, it’s time to test your protection, finalize your Docker installation if necessary, and troubleshoot any issues that may arise. This will help you maintain a robust and reliable WAF deployment. You can test the protection effectiveness either manually or automatically. Access your website using the parameters configured in SafeLine WAF: Open your browser and visit: http://: / The default protocol is HTTP; check the SSL option to use HTTPS. The hostname can be either the SafeLine IP or your website domain (make sure the domain resolves to SafeLine). The port is the one you configured in SafeLine for the site. If your website is not accessible, please refer to the Configuration Issues section. Try these URLs to simulate attacks and confirm SafeLine blocks them: SQL Injection: http://: /?id=1%20AND%201=1 XSS Attack: http://: /?html=alert(1) If SafeLine blocks these, you’ll see the attack prevented in your browser and logged in the dashboard. ✅ sudo yum update If you get errors like “Could not resolve host” or mirrorlist failures, add Alibaba Cloud repo: curl -o /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo sudo yum install -y yum-utils sudo yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo sudo yum -y install docker-ce docker-ce-cli containerd.io sudo systemctl start docker If you get x509 certificate errors when pulling images, it’s likely a system time or certificate issue.

    Check Docker Installation Details- Part 2
    Now that we've confirmed Docker is installed and running (Part 1), let's test the setup by running a simple container. This will verify that Docker can successfully download images and run containers. The Hello World Container Docker offers a lightweight "hello-world" image specifically designed to test Docker installations. This minimal container confirms that: • The Docker client can connect to the Docker daemon. 1.Let's run this test container with the following command: docker run hello-world • Check if the hello-world image exists locally This message confirms that your Docker installation is working correctly. After running the hello-world container, let's check the list of containers on your system. The container we just ran has already exited, but we can still see it in the list of all containers. 2.To see all containers (including stopped ones), run: docker ps -a The -a flag shows all containers, including those that have stopped. Without this flag, docker ps would only show running containers. STATUS column shows "Exited (0)", which means the container completed its task and exited with a status code of 0 (indicating success). The hello-world image was downloaded to your local machine. Let's verify this by listing all Docker images: docker images This confirms that the hello-world image is stored locally on your system.

    Paraglide 2.0 Migration – From Framework Glue to Clean Abstraction
    From time to time, it's necessary to bring all dependencies up to date. Most of them update easily. Paraglide.js? Definitely not.

    How to Build a Bulletproof QA Process
    In today's fast-paced tech world, speed matters. But quality matters even more. No one wants to launch a product full of bugs or deliver a user experience that doesn't live up to expectations. That's where quality assurance (QA) comes in - not as a final check, but as an ongoing, strategic process that ensures everything runs smoothly from the start. One of the biggest mistakes companies make is putting off QA until later. By then, fixing issues becomes expensive and time-consuming. A robust QA process starts right from the planning stage. QA shouldn't be an island. Developers, designers, project managers, and QA engineers should work as a team. Communication is key. Clear documentation, shared expectations, and open feedback loops help avoid misunderstandings and missed bugs. You can't fix what you don't track. That's why a well-defined test plan is essential. It sets expectations, outlines goals, and defines what success looks like. Manual testing has its place, especially when it comes to exploratory testing or checking visual and UX elements. But automation is the backbone of a scalable QA process. Smoke tests Regression tests API testing Cross-browser checks Tools like Selenium, Cypress, or Playwright can help speed up the process. Don't overdo it with automation, though - maintaining flaky tests can slow down your team more than it helps. Pro tip: CI/CD integration Hook automated tests into your CI/CD pipeline. That way, every time new code is pushed out, it's tested instantly. Faster feedback = fewer issues in production.

    🧩 Understanding Why Omit and Pick Fail with Union Types
    Omit and Pick are some of the most loved utility types in TypeScript. They let you create new types by excluding or selecting specific properties from an existing type. union types, their behavior can be misleading - and in some cases, break your type expectations type Employee = { id: string name: string job_name: string } type Customer = { id: string name: string company: string } type Person = Employee | Customer ❌ Problem: Using Omit Directly type PersonWithoutId = Omit 🧨 Actual Result: type PersonWithoutId = { name: string } Only name survives. The fields job_name and company are lost. Why? not distributive over union types. It collapses the union into a common structure, then removes the property - resulting in a simplified, lossy type. ✅ Solution: DistributiveOmit We can fix this by explicitly distributing Omit across each union member: type DistributiveOmit = T extends any ? Omit : never type PersonWithoutId = DistributiveOmit ✅ Expected Result: type PersonWithoutId = | { name: string; job_name: string } | { name: string; company: string } 🧪 Same Fix for Pick type DistributivePick = T extends any ? Pick : never type BasicaPerson = DistributivePick 🧠 Summary Table  ( 3 min )

    MSP40: The Iron Throne of Industrial Networks
    In the smoldering forges of Old Valyria, where data flows like wildfire and downtime is the true enemy, there sits a sovereign of steel and silicon—the MSP40. Forged in the fires of precision and armored against chaos, this managed Ethernet switch defends the Seven Realms of Industry 4.0 with the ruthlessness of Tywin Lannister and the foresight of Bran the Broken. Let us declare why this switch claims the Iron Throne of industrial IoT. Chapter 1: The Forge of Dragonstone MSP40 is no mere ironborn gadget. Tempered in the Foundries of Valyrian Steel, it wields powers unseen since the Age of Heroes: Dragonflame Resilience: Operates from -40°C to +85°C—hotter than Drogon’s breath, colder than the Night King’s touch. Why it shatters the old order: Legacy Switches: As reliable as Joffrey’s promises—crumbling under pressure. Chapter 2: The War of Five Ports The Battle of Blackwater Bay (Smart Factories): MSP40 commands robotic arms with the precision of Arya’s Needle, slashing downtime like Lannister soldiers. “Chaos isn’t a pit. It’s a 40% productivity gain,” it whispers. The Siege of Winterfell (Power Grids): Guards substations against EMP storms, steadfast as Brienne’s oath. “The North remembers… surge protection.” The Red Wedding (Traffic Systems): Halts data collisions at smart intersections, sparing cities from King’s Landing-level gridlock. “The network sends its regards.” The Words of House MSP40 Ports: 12 channels of fury—8 RJ45 knights and 4 SFP dragons. The Dragons of Innovation The Dark Threats Beyond the Wall Legacy Switches: Bloat like Robert Baratheon’s reign, guzzling budgets and sanity. The Prophecy of the Prince That Was Plugged In Epilogue: Winter is Here (And It’s Buffering) the MSP40 is to court chaos—a realm of molten slag and screaming CFOs.

    Why Data Versioning Matters in Machine Learning Projects
    Building reproducible models' accuracy is equally essential with model performance results in today's rapidly evolving machine learning (ML) environment. The practice of tracking and managing changes to datasets through time receives insufficient attention despite the focus on selecting the correct algorithms and adjusting hyperparameters. Data versioning practice is a critical management system that succeeds or fails an entire ML project. Reproducibility and Traceability Machine learning functions best when researchers maintain the ability to reproduce their outcomes. Model result reproducibility transforms into a random guessing process when you fail to version your data. When you retrain your model, it should deliver uniform results after each dataset variation.

    A Recipe for Success: Cooking Up Repeatable Agentic Workflows
    The Remy-Linguini Dynamic If you haven't seen the movie, here's the gist: Remy is an incredible chef with all the know-how, but he's a rat, so no kitchen access. Linguini is a kitchen worker with full access but little cooking skill. Together, they form a symbiotic relationship: Remy hides under Linguini's hat and guides him on what tools to use and when. If a customer orders fries, Linguini might freeze, but Remy scopes out the kitchen, sees what's available, and gives step-by-step instructions: "Grab a knife and a cutting board. Now slice the potato." Then, Linguini executes the plan. Agentic systems work similarly. You have three core components: A Large Language Model (LLM) An Agent Tools The LLM is like Remy; it is full of knowledge and reasoning, but has no hands-on access. Th…  ( 7 min )

    Implementing a JavaScript plugin system using Rust with Deno can be an exciting challenge. This guide explores how to set up such a system that can integrate JavaScript execution alongside Rust's efficiency while leveraging Deno's secure permission model and web APIs. Understanding Deno and its Permission Model Deno is a modern runtime for JavaScript and TypeScript that offers robust security through permissions. It allows developers to run JavaScript code outside of a browser-controlled environment with controls over which files and network access is available. This makes it an ideal candidate for implementing a plugin system where different scripts can be executed with varying levels of control. Setting Up Your Rust Project with Deno To get started, you need to create a new Rust project.…  ( 5 min )

    Cloud vendor lock-in! How much should I be scared of? 😱
    Originally written at pooyan.info Who is the author? Check out my profile on LinkedIn. Vendor lock-in refers to a situation where an organization becomes overly dependent on a specific vendor's products or services, making switching to alternatives costly, time-consuming, or technically difficult. Over the years, many companies have experienced frustration when trying to move away from large vendors like IBM, Microsoft, or Oracle due to contractual constraints, proprietary technologies, and sudden pricing changes. A recent example is VMware's acquisition by Broadcom, followed by significant pricing changes that disrupted many businesses.

    How to Fix Java JAR 'No Main Manifest Attribute' Error?
    Introduction If you’ve ever encountered the no main manifest attribute error while trying to run a JAR file in Java, you’re not alone. This common issue arises when the JAR file lacks the necessary metadata to specify the entry point of your application. This article will guide you through understanding this error, configuring your pom.xml file correctly, and successfully packaging your Java application into a runnable JAR file. Understanding the Error When you package a Java application into a JAR file, the Java Runtime Environment (JRE) looks for a specific entry in the JAR's manifest file to understand where the main class is located. If this entry is missing, Java throws the no main manifest attribute error. This typically happens when the maven-jar-plugin isn't correctly configured in…  ( 5 min )
    Python Code Quality: Style Conventions and Linting Tools
    Leapcell: The Best of Serverless Web Hosting The Python code style guide is not set in stone. It evolves continuously with the development of the language. Some old conventions are gradually phased out, and new ones keep emerging. At the same time, many projects have their own coding style guides. When there are conflicts, the project-specific guides should be followed first. However, there is an important principle to keep in mind: "The stupid persistence in consistency is the monster of ignorance", which is a profound insight from Guido. Since code is often read more frequently than it is written, the core goal of the style guide is to improve code readability and keep all kinds of Python code consistent. As PEP20 says, "Readability counts". The style guide emphasizes consistency. While …  ( 10 min )

    DevLog 20250506 C# Video Processing Foundation Library
    Today I need to find a suitable foundational library for video processing. FFMpegCore works for one-shot things but despite a fluent API, its interface is still too command line like. Here is what I found out: OpenCvSharp LibVLCSharp FFMediaToolkit Frames ✅ decode / encode ✅ (via callbacks) ❓ Audio ❌ ✅ decode / encode / mux ❓ Extra libs ~5 MB/platform +7 MB +7 MB Licence Apache‑2.0 LGPLv2.1 MIT Platforms Win / mac / Linux / Arm Win / mac / Linux / iOS / Android Win / mac / Linux LibVLCSharp seems more focused on directly displaying things (e.g. in Xamarine and WPF) instead of low-level API based processing; FFMediaToolkit, on the other hand, still depends on FFMPEG and can't avoid licensing issue. Eventually, I had to go with separate video + audio processing in favor of OpenCvSharp (it's Apache-2.0 by the way). Notice OpenCVSharp has some advantage over EmguCV for custom dev: OpenCvSharp Emgu.CV Licence Apache-2.0 (fully permissive) GPL v3 or commercial licence Interop model Pure P/Invoke (no C++/CLI), works on any .NET core runtime Historically C++/CLI wrapper (needs Windows for full feature set), .NET Standard P/Invoke layer added later NuGet size (native) 4–6 MB per RID (modular runtime packages) 30 MB + for the “opencv‑world” monolith, or 90 MB for emgucv‑runtime‑ubuntu GPU (CUDA) support Provided in separate OpenCvSharp4.runtime.dnn package Official CUDA builds, but Windows‑only binaries unless you compile yourself API surface ~1:1 with OpenCV C++ names (easy to port C++ samples) Thicker .NET façade (e.g. Image types), extra helpers Cross‑platform stability Actively tested on Windows / Linux / macOS / arm64 Windows the main focus; Linux/macOS possible with libopencv from distro or big runtime package Learning curve If you know OpenCV C++ you feel at home Higher‑level abstractions can be friendlier for newcomers Commercial support Community‑driven Paid licences & support available from Emgu CV, Inc.  ( 3 min )

    [Patch Notice] I found a problem of HeadlineSquare's HTML rendering, and today I patched the bug. All clear now.
    Semicolons were often added to the end of URLs, especially in r/Conservative summaries, and they became a part of the hyperlinks wrongly, making some of the hyperlinks unusable. I often randomly test the hyperlinks and they all worked, but I just realize that I only test the longest hyperlinks, because I think they are the ones more prone to hallucinations. I didn't find any hallucinations. But yesterday I clicked some of the simpler links of r/Conservative summaries and I got 30% of them not working. I panicked because I thought the hallucination caught me off guard, but then I realized all the links were real, but they each got an additional ";" attached to them, which was redundant. The links themselves were correct but the semicolons I used to declare the end of line was wrongly identified as part of the URLs. The fix was simple. I removed all redundant semicolons from all my current and previous output documents. I am really surprised of this bug because it affected so many links but it evaded my "random" sampling for so long, because I didn't test the rendered URL links very thoroughly, and I thought very long and complex links were at higher risks of hallucination, so I tested those a lot. Weird enough, those never had problems, but the shorter, simpler links did. I am very sorry for the potential confusion it might have created.  ( 3 min )

    Falling DXY part of US financial system’s ‘long-term transition’ — Will Bitcoin continue to shine?
    What to know: Lyn Alden says a weaker dollar is necessary for the US to stabilize its financial system. Bitcoin and gold are well-positioned to benefit from de-dollarization. Sovereign wealth funds and various nations are already increasing their Bitcoin exposure as the dollar’s global dominance starts to wane. The weakening of the US dollar (DXY) is no longer headline news. With mounting disruptions across the US economy, a declining greenback has become part of the backdrop. Since the start of 2025, the US Dollar Index has dropped 11%, now hovering around levels last seen in April 2022. Markets have largely responded with a shrug. After all, in times of deep restructuring, isn’t some dollar weakness to be expected? The trouble is, this might not be a temporary dip. The dollar’s slide…

    Binance's BNB Chain rebounds amid institutional, DeFi adoption
    Binance-affiliated BNB Chain has rebounded after a period of stagnation in 2023 amid accelerating institutional and decentralized finance (DeFi) adoption.  During the past year, BNB Chain has benefited from multibillion-dollar inflows into DeFi, US exchange-traded funds (ETFs), and rising trading volume at affiliated centralized exchange (CEX) Binance.  Consequently, the blockchain network’s native BNB token (BNB) has emerged as among the market’s most resilient cryptocurrencies, surpassing all-time highs in the first quarter of 2025 even as the broader crypto market trended downward.  “This resilience isn't just about price action — strong fundamentals also back it,” Joao Wedson, CEO of investing analytics platform Alphractal, said in an April X post. “Binance has built a massive ecosyste…
    Ethereum Pectra upgrade adds new features — How long before ETH price reacts?
    Key takeaways: Reclaiming the $2,200 level remains the first price challenge for ETH.  ETH price could recover if the Pectra upgrade leads to a surge in DApp and Ethereum network activity.  Ethereum successfully implemented a key network upgrade on May 7, but Ether (ETH) price and its derivatives metrics showed little response to the upgrade.

    SocialFi has failed to take off — Here's what needs to change
    Opinion by: Anurag Arjun, co-founder of Avail  On paper, SocialFi is a no-brainer. It promises to shift the balance of power in social media — giving people control over how their content and personal data are used and monetized. It even offers users a stake in the $200+ billion social media advertising market, a pie currently devoured almost entirely by giants like Meta. And yet, SocialFi platforms today feel more like digital ghost towns than the bustling hubs of Web2.

    Crypto miner deserts Pennsylvania site, fails to plug wells: Report
    Cryptocurrency miner Diversified Energy quietly vacated a natural gas-powered crypto mining site in Elk County, Pennsylvania, reportedly leaving behind unplugged wells and regulatory violations.

    Zerebro dev’s death in question as ‘proof’ surfaces on X
    Members of the crypto community are circulating apparent “proof” that Zerebro developer Jeffy Yu faked his suicide as he promoted his new memecoin during a Pump.fun livestream on May 4.

    The Relationship Between GDP and Stock Market Performance
    The relationship between Gross Domestic Product (GDP) and stock market performance is a subject of considerable interest to economists, investors, and policy makers alike. GDP measures the total value of goods and services produced by a country, and it serves as an indicator of the health and growth of an economy. The stock market, on the other hand, reflects the collective value of publicly traded companies and serves as a platform for buying and selling shares. Both metrics are often used to gauge economic conditions, yet their relationship is more complex than a simple correlation. While there is a connection between GDP growth and stock market performance, this relationship is influenced by various factors, including investor sentiment, economic policies, and external events. In some c…  ( 7 min )
    Creating A2A Agents with Python: Building a Simple Math Agent - Part II
    In this blog post, I'll walk through how I built a simple Agent-to-Agent (A2A) math service using Python. The A2A protocol is Google's initiative to standardize how AI agents communicate with each other, creating an interoperable ecosystem of specialized AI services. The Agent-to-Agent (A2A) protocol is designed to enable AI agents to communicate with each other using a standardized messaging format. This allows developers to create specialized agents that can work together, each handling specific tasks they're optimized for. Standardized communication between AI systems Ability to chain specialized services together Easier integration of AI capabilities into applications I created a basic A2A agent that performs a simple but useful function: summing numbers from a comma-separated list whi…  ( 6 min )
    Testing in the Era of Microservices and APIs: A Leadership Perspective
    There was a time when software releases were slow and monolithic—but at least everything was in one place. Now, we move faster. But that speed? It comes at a cost. Today, we live in a world of microservices, APIs, and distributed everything. The architecture is elegant. The orchestration is powerful. But testing? That’s where things get tricky. As a quality engineering leader, I’ve seen firsthand how this complexity tests more than just code—it tests our assumptions about ownership, accountability, and what “done” really means. In a microservices ecosystem, a single user journey might hit a dozen services. Each is built, deployed, and owned by a different team. And while unit tests may pass with flying colors, it’s the integration points—those fragile handshakes between services—that often…  ( 4 min )
    How to Optimize Java Map for Variable Key Structures?
    Introduction In Java, managing complex key structures dynamically is a common challenge, especially when dealing with API response times and performance issues. In your scenario, you're saving keys in a map formatted like Krishna/thota/date/x/y/z while supporting wildcard characters (*) to match various entries. However, this approach leads to performance overhead due to the necessity of comparing strings, which can be inefficient when handling over a million records. We’ll explore better data structures and solutions to enhance performance while allowing for the flexibility you need for matching. Understanding the Performance Issue You mentioned that your current implementation takes approximately 200 milliseconds when you have more than one million records. This degree of latency can aff…  ( 5 min )
    Beyond Heroes and Villains
    When a small purple dragon leapt joyfully onto television screens in 1998, gaming felt simpler. Spyro's tale was charmingly clear-cut: dragons good, Gnorcs bad. Yet, as those early fans grew alongside the medium itself, uncomplicated childhood memories gave way to reflective curiosity. With maturity comes the realisation that even playful narratives can unwittingly reveal complex truths—sometimes challenging, always intriguing. Among Spyro's cast, no group invites this reconsideration quite like the Gnorcs. Originally depicted as brutish, green-skinned adversaries to vanquish without second thought, today they stir conversation far beyond simple nostalgia. Central to this renewed interrogation of Spyro's world is Gnasty Gnorc himself. Once an outright villain, his motivations now appear le…  ( 6 min )
    The Documentation Paradox
    Most teams spend hours documenting everything. Notion workspaces. Confluence pages. GitHub wikis. You name it. But here’s what happens: ☑️New hires still get stuck. ☑️Devs still ask questions that are, “Somewhere in the docs” and crucial context gets lost. This is the Documentation Paradox: The more you write, the harder it gets to find, trust, and maintain what actually matters. Conventional wisdom says, “Async teams need tons of docs!” But I’ll say: More docs often mean less clarity. Here’s why: First, there's the maintenance burden. Every line of documentation is a liability that needs updating as your codebase evolves. How many teams actually do that? Second, comprehensive documentation creates a false sense of security. Teams believe they're covered because it's in the docs somewhere. What you should do is treat documentation as a conversation, not an artifact. Use tools that make updating docs as easy as sending a message. Encourage annotations and questions directly in the documentation. And remember the 20/80 rule: 20% of your features generate 80% of questions. Focus your efforts there. The goal isn't to have everything documented – it's to have the right documentation that actually helps your team move faster. This is why every Rally session lives forever inside Jira No more sorting through old Slack threads. Every discussion stays tied to the task, so your team’s knowledge grows with the work—not in a dusty folder.  ( 3 min )

    How to Humanize Strings in C# Like Ruby's Humanize?
    In C#, there isn't a built-in method equivalent to Ruby's humanize for turning strings into a more natural format, but you can create functions to achieve this easily. In this article, we'll explore how to convert strings while following the two scenarios provided in your request: changing capitalization and formatting string cases to appear more human-friendly. Understanding the Humanization Process When we discuss 'humanizing' a string, we're typically referring to text transformation that makes it easier for humans to read or understand. This can involve adjusting capitalization, changing the case, or formatting text to look more polished and readable. Unlike Ruby, where the humanize function applies well-defined transformations, C# requires us to craft our own methods. Implementing a S…  ( 4 min )

    How to Fix Diesel Count Query Error in Rust
    Introduction When working with Rust and Diesel, you may encounter various issues, especially when performing count queries. In this article, we'll examine a specific error that arises from executing a count query using Diesel with PostgreSQL. The error message states, 'the trait bound i32: FromSql is not satisfied'. This indicates a type mismatch in your query resolution. Understanding the Error The error is primarily triggered because the Diesel ORM expects a specific data type from the SQL count result. Typically, when using the count function in a SQL query, the result is of type BigInt in PostgreSQL, which corresponds to i64 in Rust. However, your code attempts to return the result as an i32, leading to the compile error. Step-by-Step Solution Changing Return Type to i64 Th…  ( 4 min )

    How to Use CodeIgniter Query Builder for SQL Queries?
    When working with CodeIgniter, you might want to utilize its query builder feature for better performance and security. For instance, let's consider the SQL query: SELECT * FROM questions WHERE course_id = 13; This query retrieves all records from the 'questions' table where the course_id is equal to 13. However, using raw SQL queries in CodeIgniter, as shown below, can lead to issues: $query2 = $this->db->query('SELECT * FROM questions WHERE course_id = 13', false); Why is This Query Problematic? Using this method can lead to potential SQL injection vulnerabilities, and it's not as efficient as using the CodeIgniter Query Builder. Additionally, the parameters need to be validated or sanitized especially when you’re dealing with user input. Using the Query Builder in CodeIgniter The Code…  ( 4 min )

    Dica de TI: O que são tipos de dados?
    Dica de TI será uma série de posts com conteúdo sobre tecnologia. São posts curtos explicando alguns conceitos. Um tipo de dados representa as características de uma variável que determina que tipo de dados ela pode conter. Exemplo tipos de dados primitivos: Essas variáveis guardam valores. Exemplo: números, byte, short, int, long, float, double e boolean char. A aplicação guarda o endereço em memória e não o valor em si. Importantes casos são as arrays e os objetos. Exemplos Arrays, Objetos, Classes, String. Os tipos primitivos são predefinidos (já definidos) em Java. Tipos não primitivos são criados pelo programador e não são definidos. Tipos não primitivos podem ser usados para chamar métodos para realizar determinadas operações, enquanto tipos primitivos não podem. Um tipo primitivo sempre tem um valor, enquanto os tipos não primitivos podem ser null. Um tipo primitivo começa com uma letra minúscula, enquanto os tipos não primitivos começam com uma letra maiúscula. Exemplos de tipos não primitivos são Strings , Arrays , Classes, Interface , etc.  ( 3 min )
    Sightful's Spacetop Is a Better, More Practical Spatial Computing Experience
    Sightful’s Spacetop for Windows is a $899 bundle (plus a $200/yr subscription after year one) that turns your compatible Intel-powered laptop and Xreal Air 2 Ultra smart glasses into a multi-monitor, spatial-computing workspace. Wired gave it a 9/10, praising its polished software, comfy glasses (with dimming for outdoor use) and the private, ultra-portable productivity it delivers—arguably edging out Apple’s Vision Pro at a fraction of the price. It’s not all sunshine, though: the setup looks a bit dorky, only works on select Intel CPUs for now, saps battery life in a hurry and the glasses’ field of view could be wider. Still, if you’ve been dreaming of carrying your home-office everywhere, Spacetop might finally make it happen.  ( 3 min )

    Implementing the Royal Game of Ur using Mistral's Codestral
    In this post, I test how Mistral's Codestral, the model specifically trained to generate code, compares to the Mistral's Le Chat, the general AI chat. For my experiment, I use the Royal Game of Ur, an ancient Babylonian game that I already implemented using Le Chat. At least in my experiment, Codestral's performance is, frankly, disappointing. While it produces code that follows a certain architecture, the code quality is low. In fact, it even generates a statement of the form a = foo() where a has a different type from what foo() returns. Read on for more details. After the same prompt as with Le Chat, Codestral's response is: To implement the Royal Game of Ur in Python, we need to define several components: Game Board: Represent the board and the special squares.

    Cloud-Native: Are You Paying for What You Use… or for What You Provision?
    Everyone’s in the cloud. Stacks have migrated. Infrastructure is containerized. CI/CD pipelines are green. But behind the wave of “cloudification”, one question lingers: Have we really changed the way we think? Because on the surface, everything looks modern. But underneath? ⏱️ Services running 24/7 💤 Containers sitting idle, waiting for traffic that never comes 💸 Bills growing, even when no one clicks “deploy” And in every retro, every finance meeting, the same old line: “The cloud is expensive.” But is it really the cloud that’s expensive? Or is it… The quiet luxury of feeding CPUs that are just bored? Let’s be honest. Cloud-native isn’t Docker. It’s not Kubernetes. It’s not Terraform, or some magic mix of YAML, containers, and CI/CD.

    Smarter RAG Systems with Graphs
    Introduction: So You Want Your LLM to Stop Guessing Everyone’s buzzing about Retrieval-Augmented Generation (RAG) like it’s the second coming of AI engineering. And honestly? It kinda is. Your large language model is excellent at confidently making things up—because it doesn’t actually know anything beyond whatever data it was last trained on (hello, 2023). That’s where RAG comes in: bolting on real, external knowledge so your LLM stops hallucinating and starts reasoning. But here’s the thing: knowledge isn’t just about facts. It’s about how things connect. And when relationships matter, you don’t want a flat file or a relational torture device. You want a graph. Enter the graph database.

    EventTarget - CustomEvent | components communication in React - part Three
    In the first and second parts, we focused on creating two different patterns for handling data flow in React. EventTarget is the foundation of the browser’s event system. addEventListener, removeEventListener, and dispatchEvent. Many core Web APIs including DOM elements like , , , as well as document and window inherit from EventTarget. When we attach an event handler to a DOM element—like in the picture above—we’re actually subscribing to that element through one of its event channels. In this case: The button is the publisher (or emitter) The callback function passed to addEventListener is the subscriber (or listener) So when a user clicks the button, the button emits a 'click' event, and all registered listeners for that event type are notified and executed.

    The Spirit of Plan 9 on the Web
    If you go back to the first talk ever given on webhooks, it opens on the command-line. Specifically the Unix shell, focusing on one of its defining features: pipes. The idea was that pipes brought a new level of compositionality to programs, and webhooks could bring a new level of compositionality to web apps. Perhaps you could say I was trying to bring the spirit of Unix to the web. With this last release of Wanix, I'm at it again. This time with the successor to Unix, a little known operating system called Plan 9 from Bell Labs. Plan 9 has been on my mind for quite a while. In fact, around the time of that first talk on webhooks, the team behind Unix and Plan 9 was being re-assembled to create the Go programming language.

    TS2327: Property '{0}' is optional in type '{1}' but required in type '{2}'
    TS2327: Property '{0}' is optional in type '{1}' but required in type '{2}' TypeScript has quickly become a favorite tool for developers building scalable and maintainable JavaScript applications. At its core, TypeScript is a superset of JavaScript—it builds upon JavaScript by introducing static typing, as well as other modern programming concepts that make your code safer and easier to manage. Static typing means that developers can explicitly define the types of data (like string, number, or boolean) their variables and functions work with, catching potential errors during development instead of at runtime. If you're new to TypeScript, or want to sharpen your existing skills, consider following our blog or using advanced learning tools like gpteach.us to explore how modern AI tools ca…  ( 6 min )
    TS2333: 'this' cannot be referenced in constructor arguments
    TS2333: 'this' cannot be referenced in constructor arguments TypeScript is a statically-typed superset of JavaScript designed to add type safety and developer-friendly features to JavaScript code. A "superset" means that TypeScript builds on JavaScript by adding new functionalities, while still allowing you to write plain JavaScript. One of its most powerful features is the introduction of types (a system to define constraints on the structure of your data). This is immensely beneficial when working in large projects to detect errors at compile time, ensuring your codebase is reliable and maintainable. Types in TypeScript help us describe the shape of an object, function, or data. For instance, when you define a function or an object, you can explicitly specify what inputs it expects and…  ( 6 min )
    TS2332: 'this' cannot be referenced in current location
    TS2332: 'this' cannot be referenced in current location TypeScript is a popular open-source programming language developed by Microsoft. It’s often referred to as a superset of JavaScript because it builds on JavaScript by adding optional static types. These types allow developers to define the structure and behavior of variables, functions, and objects, making programs easier to debug and maintain. TypeScript compiles to plain JavaScript for execution, which means it seamlessly integrates with existing JavaScript projects. Simply put, types in TypeScript are what allow you to specify the kind of data a variable or function should handle. For instance, you can declare that a variable must always hold a number, a string, or a custom structure (like objects or classes). By catching errors …  ( 6 min )
    TS2331: 'this' cannot be referenced in a module or namespace body
    TS2331: 'this' cannot be referenced in a module or namespace body TypeScript is a powerful language that builds upon JavaScript by adding optional static typing. By introducing "types" (representations of data such as strings, numbers, and objects, among others), TypeScript allows developers to write more predictable and maintainable code. It’s often referred to as a superset (a language that extends the features of another) of JavaScript, meaning all valid JavaScript code is also valid TypeScript code. A major advantage of TypeScript is its ability to catch errors during development, before the code is executed. However, while it enhances safety and boosts productivity, developers may sometimes encounter compiler errors that seem confusing at first. One such error is TS2331: 'this' ca…  ( 5 min )
    TS2329: Index signature for type '{0}' is missing in type '{1}'
    TS2329: Index signature for type '{0}' is missing in type '{1}' TypeScript is a strongly typed superset of JavaScript. This means that it builds on top of JavaScript by adding an optional type system (a way to define and enforce the kinds of data being used in your code). TypeScript is a powerful language designed to catch errors early during development, making your JavaScript codebases more robust and maintainable. In TypeScript, "types" play a central role. A type defines the shape of data, specifying what kind of data will be stored, its expected structure, and the operations you can perform on it. For example, string, number, boolean, and object are common types used in TypeScript. Types ensure that your code only operates on the data it was designed to handle; if it doesn’t match t…  ( 6 min )
    TS1433: Decorators may not be applied to 'this' parameters

    🚀 Turning Videos into Interactive Courses with AI
    How I built VidSabio.com by combining multiple LLMs into a robust processing pipeline I recently launched VidSabio, a platform that transforms ordinary videos into structured, interactive learning experiences — automatically. 🎥➡️📚 But this didn’t come together overnight. At first, I thought a single LLM could handle everything: analyze the video, transcribe it, generate quizzes, build a course. Easy, right? Wrong. It turned out the real breakthrough came when I stopped looking for one model to do it all — and instead built a pipeline of specialized steps, each powered by the best tool for that specific task. Here’s the high-level breakdown of how it works: User uploads a video Video is processed through a multi-step pipeline: Frame extraction (FFmpeg) Audio transcription (Google Speech-to-Text) Visual analysis (Gemini / GPT-4 Vision) Content summarization + topic generation (Gemini Pro) Course structure generation (GPT-4) Interactivity injection (quizzes, accordions, etc.) Final course can be edited and exported as SCORM or HTML This is all built using Vue 3, Firebase, and various LLMs (OpenAI + Gemini) stitched together through Cloud Functions. By distributing the heavy lifting across multiple LLMs and APIs, I was able to: Improve accuracy Scale more efficiently Debug and retry isolated steps Customize outputs based on step-level feedback Frontend: Vue 3 + Tailwind Backend: Firebase Functions + Firestore + Storage AI: GPT-4.1, Gemini Pro, Whisper, Google Speech-to-Text Analytics: PostHog Export: SCORM, HTML Here's a stylized diagram of the flow: (Insert your HappyAlien-styled image here) This was built with plenty of detours, dead ends, and "aha" moments. If you're building with LLMs, I encourage you to explore multi-model orchestration — it might be the key to your next breakthrough.

Takes a GitHub repo URL Pulls the README Feeds it to an AI image model Displays the generated image alongside project metadata Adds it to a public gallery You can even choose the image style you want: Conceptual & Techy Infographic Abstract & Minimalist Direct & Clear It’s built with Vue 3 + Tailwind, uses Supabase for storage and data, and everything runs through a lightweight backend on Render. I love browsing GitHub, and I wondered: “What would this project look like if it were a picture?” So I built GitVisualize as a fun experiment in combining AI, dev culture, and a bit of creativity. Some of the results are surprisingly expressive. Frontend: Vue 3 + Tailwind Backend: Node/Express (Render) AI: OpenAI gpt-image-1 Storage/DB: Supabase Design direction: Lighthearted “Happy Alien” aesthetic 🛸 ➡️ https://gitvisualize-web.onrender.com/ Paste a repo, pick a style, and see what AI dreams up! I’d love feedback, ideas, or feature suggestions. James Kingsley – HappyAlien.ai #buildinpublic #sideproject #ai #webdev #openai #supabase #vue #showdev  ( 3 min )
    Leading with Conviction, Listening with an Open Mind
    A piece of feedback that reshaped how I think about conviction, consensus, and presence when you're the most senior person in the room. Originally published at mustafatorun.me A few years ago, I wrote a design document outlining a few different options. It was for a group more experienced than me—not in the domain, but in the industry. I knew the problem well. I had done the work. But still, I softened my position. I showed the tradeoffs, invited discussion, and held back from saying with confidence, “This is the direction I believe we should take.” In a pre-review, someone I trusted — someone more experienced than me — called it out. The document lacked conviction. It read like I was asking the group to decide for me. They reminded me that I was the expert in this domain — not them. What …  ( 4 min )

    10 JavaScript Array Functions Every Dev Must Know (or Risk Falling Behind)
    If you’ve started learning JavaScript, you’ve probably worked with arrays — those magical lists that hold multiple values. But knowing how to use arrays effectively means understanding the array functions that JavaScript gives us. Let’s break down the most powerful and commonly used array functions that every developer should know. An array is a special variable in JavaScript that can hold more than one value at a time: const fruits = ['apple', 'banana', 'cherry']; .push() – Add to the End fruits.push('mango'); console.log(fruits); // ['apple', 'banana', 'cherry', 'mango'] .pop() – Remove from the End fruits.pop(); console.log(fruits); // ['apple', 'banana', 'cherry'] .shift() – Remove from the Start fruits.shift(); console.log(fruits); // ['banana', 'cherry'] .unshift()…  ( 4 min )

    How to Transform Snake Case to Camel Case in TypeScript?
    When working with APIs, we often encounter data in formats that do not match our application's preferred coding style. For instance, if you're using TypeScript and Vue.js, you might receive data in snake_case from an API but prefer to work with camelCase throughout your application. The good news is that you can easily transform this data without losing type safety. Let's delve into how you can achieve that with the help of interfaces and utility types in TypeScript. Understanding the Problem When you define an interface such as MergedReviewDetails, you structure your data according to your application's needs. An example of this could be: export interface MergedReviewDetails { parentReview: Mmcid; childReviews: Mmcid[]; } However, the API might return data with properties in snake_ca…  ( 4 min )

    What is Tailgating?
    In the world of corporate security, not all breaches involve sophisticated hacking tools—some simply walk through the front door. Tailgating, a subtle yet dangerous form of intrusion, happens when an unauthorized person gains access to a restricted area by following closely behind someone who is authorized. It's a tactic that relies less on technology and more on exploiting human behavior. Attackers often masquerade as employees, contractors, or delivery workers. They may carry packages, wear uniforms, or claim to have forgotten their access badge—all to lower suspicion. Once inside, these individuals can do far more than just roam the premises. They might access critical systems, plant malicious software, or steal sensitive equipment. Pretending to be a colleague and asking someone to hol…  ( 4 min )

    The Day I Discovered enumerate()
    It was a regular evening debug session. My code was working, but something about it just felt off. I was looping over a list—like always. for i in range(len(my_list)): value = my_list[i] # Do something with value and i Nothing wrong, right? Except... I was starting to hate reading my own code. range(len(...)). Too much manual indexing. 👀 The Realization for i, value in enumerate(my_list): # Do something with i and value Wait... what? No range(len(...))? No messy indexing? ✅ Cleaner 🧠 Why it works: enumerate() is a built-in Python function that returns both the index and the value of items in an iterable—in one shot. It’s like your loop suddenly gained superpowers. 💡 Bonus Tip: for i, val in enumerate(my_list, start=1): print(f"Item {i}: {val}") Perfect for user-facing counters. No more +1 hacks. 🚫 Never Again... No more range(len(...)) unless I really need it. Now, it’s all enumerate(), all day. ✨ Moral of the Story: If you're reaching for range(len(...)), stop and ask yourself— What would enumerate() do? 😎  ( 3 min )
    How to Access Fields with Spaces in Lumerical FDTD Farfield Data?
    When working with Lumerical FDTD simulations, access to specific fields from the results of a far-field projection monitor might sometimes be challenging, especially when it comes to field names with spaces. In your case, you're able to access standard fields like E2 and Es easily: farfield = getresult("monitor", "farfield"); E2 = farfield.E2; Es = farfield.Es; However, when it comes to the field "Ep vs angle", an error arises. This can happen due to the space in the field name, making direct access using dot notation invalid. Understanding the Structure of the Farfield Object The farfield object typically contains several fields, including E2, Es, and multiple arrays or matrices concerning angles and wavelengths. The fields you can access directly using dot notation are designed to be id…  ( 4 min )

In this article, we will explore a specific case of a NoSuchMethodError that arises during navigation to a Compose-based screen of a third-party SDK. This problem can be particularly frustrating, as it does not occur when running the app straight from Android Studio, but instead manifests when generating a debug APK via the command line. Understanding the Issue The problem at hand is encapsulated by the error message: java.lang.NoSuchMethodError: No static method slideIntoContainer(...) in class androidx.compose.animation.AnimatedContentTransitionScope. This error typically indicates that the compiler is unable to find a specific method at r…  ( 4 min )
    The Hallmark of Great Developers: Writing Simple Code
    "If you can't explain something to a first-year student, then you haven't really understood." —Richard Feynman This is one of my favorite quotes.

    RDMA에 대하여
    RDMA(Remote Direct Memory Access)는 네트워크를 통해 서버 간에 CPU 개입 없이 메모리를 직접 읽고 쓰는 기술이다. 주로 고성능 컴퓨팅(HPC), 대규모 데이터 처리, AI/ML 분산 학습 환경 등에서 낮은 지연 시간과 높은 대역폭을 제공하기 때문에 많이 사용한다. 1. RDMA의 기본 개념 일반적인 네트워크 통신 방식에서는 데이터를 전송하려면 CPU가 메모리에서 데이터를 읽고, 네트워크 인터페이스 카드(NIC)로 복사한다. 이 복사한 데이터를 네트워크를 통해 데이터를 보내고, 수신 측에서도 CPU가 데이터를 NIC에서 메모리로 복사한다. 이 과정에서 CPU, 커널, 복사 작업 등이 개입되어 지연(latency)과 CPU 오버헤드가 큰 현상이 발생한다. 반면, RDMA는, CPU나 운영체제(OS) 커널의 개입 없이, 원격 시스템의 메모리에 직접 읽기(read) 또는 쓰기(write) 작업을 수행한다. 다시 말해, 데이터가 직접 메모리에서 메모리로 이동한다. 2. RDMA가 동작하는 방식 (1) 메모리 등록 (Memory Registration) 송신자와 수신자 모두 RDMA NIC(HCA: Host Channel Adapter)를 사용함. RDMA를 사용하기 위해서는 사용할 메모리 영역을 등록(pinning)해야 함. 이 과정에서 해당 메모리는 물리 메모리에 고정되고 커널이 RDMA NIC에 메모리 주소를 알려줌. (2) Queue Pair 생성 RDMA 통신은 QP(Queue Pair)라는 구조를 통해 이루어짐.

Calculating Remaining Minutes: By taking the remaining seconds after accounting for hours and dividing by 60. Calculating Remaining Seconds: By taking the remainder from the minutes calcul…  ( 4 min )

    The Scraping Story: The Car Repair Team
    The Scraper: The Collector of Car Parts Each day, the Scraper ventured out, gathering essential tools—brake pads, spark plugs, and oil filters—meticulously putting them in his storage room. This storage room, filled with parts, was like a database, organizing all the precious data he gathered from various sources. For instance, one day, the Scraper found a batch of brake pads. He cataloged the details, from brand to condition, and stored it safely. This was like collecting the latest prices from websites, storing them in a file for future use. The Backend Guy: The Toolbox Handler Whenever the mechanic—the Frontend—needed a specific tool, they would call out, “I need a 10mm wrench!” The Backend Guy, standing by the toolbox, would find the correct tool and hand it over with precision. He didn't fix the car himself, but he made sure the mechanic had exactly what was needed at the right time. Just like that, the Backend Guy managed the storage of all the data and ensured it was always ready when the Frontend needed it. When the mechanic asked for the current price of the Euro in Toman, the Backend would retrieve that data and send it in a neat package—a JSON response—ready to be used. The Frontend Mechanic: The User Interface When the mechanic needed a part, they'd shout, "I need a 10mm wrench!" The Backend Guy would respond, handing over the tool, and the Frontend Mechanic would get to work. The mechanic didn’t care how the part got there, as long as it was the right one. In the same way, the Frontend Mechanic used the data provided by the Backend to create an amazing display for the car's dashboard. They made sure the car (or website) looked stunning, with neatly organized parts (like the prices) and a smooth-running engine (user interface). Whether it was showing prices in a nice table or providing a simple, user-friendly experience, the Frontend Mechanic made sure everything was visually appealing and functional.  ( 4 min )

    IaCConf 2025: Why Infrastructure as Code deserves its own conference
    Infrastructure as Code (IaC) has come a long way since its beginnings. What started as spinning up cloud resources has now grown into a full-blown ecosystem with a very engaged community. IaC on its own can add a lot of complexity to your processes and cause more issues, but combined with governance, compliance, security, deployment strategies, self-service, it easily becomes the fuel your delivery engine needs. This year, IaCConf debuts as a virtual event by bringing together this community, and it’s shaping up to be one of the most relevant and practical events in the space. Unlike broader DevOps/SRE or cloud-native events, IACConf is focused on the challenges and innovations around defining infrastructure as code. That means the content goes deeper, the conversations are more relevant, and the takeaways are directly applicable to your processes. There will be sessions on: Getting started with IaC Managing IaC at scale across teams and environments (using OpenTofu, Terraform, Ansible, Crossplane, and others) Platform Engineering and IaC How IaC impacts your maturity AI in IaC And that’s just scratching the surface. Check out the full agenda here. One of the things I appreciate most about this conference is that it’s not about product pitches or high-level fluff. Practitioners share what worked, what broke, and how they improved. Whether you are just starting out, are in the trenches, or shaping platform strategy, there’s something for you here. On another note, I’m also excited to contribute to this year’s lineup with a session on Getting Started with IaC, together with my colleague Emin Alemdar. But honestly, I’m just as excited to learn and to connect with others working through the same challenges. The event will be on Thu, May 15, 2025 @ 11:00am EDT, so don’t forget to register here.

    Is It Safe to Transmute Between OuterA and OuterB in Rust?
    In Rust, understanding how std::mem::transmute functions between different types is crucial for ensuring memory safety and type integrity. This brings us to an interesting question: Is it safe to transmute between two custom struct types, OuterA and OuterB, which only differ by their inner types — InnerA and InnerB? Let's explore what the repr(transparent) conveys and clarify the implications of transmuting types in Rust. Understanding repr(transparent) The #[repr(transparent)] attribute in Rust is used to indicate that a struct represents a single variant of a type that can be safely treated as equivalent to its single field. This is particularly useful for effectively working with opaque types or for implementing newtype patterns. In the provided example, we have the following structur…  ( 4 min )

    How to Properly Implement mat-list and mat-divider in Angular?
    Introduction When developing Angular applications, particularly with Angular Material, you might encounter issues regarding the mat-list and mat-divider components. Many developers wonder whether to use ngFor inside the mat-list or the mat-list-item and how to correctly place the mat-divider. Let’s delve into this topic to clarify which method is best. Why This Issue Arises The confusion around where to implement ngFor and the positioning of mat-divider often stems from how Angular handles component rendering. Using ngFor within the mat-list means that each item is rendered as part of the list itself; thus, the dividers are less likely to show correctly if their placement isn’t considered carefully. Conversely, applying ngFor to mat-list-item makes each list item independent and potentiall…  ( 4 min )

    What is a Proxy Firewall and How Does It Work?
    A proxy firewall, often referred to as an application-layer or gateway firewall, acts as an intermediary between a user’s system and external servers. Instead of allowing direct communication, it processes and forwards requests on behalf of users. This not only hides internal network details from outsiders but also allows the firewall to thoroughly inspect data before it reaches its destination. Unlike traditional firewalls that operate primarily at the network or transport layer, proxy firewalls operate at the application layer. They intercept requests, evaluate the content, and relay approved traffic. This additional layer of inspection allows for more granular control, helping detect threats embedded in seemingly legitimate requests—such as malware hidden in web traffic or email attachm…  ( 4 min )

    🧠🚀Open project for discussion: OS Against Porn - Anyone interested in implementing it?🧩
    Hello, I have an ambitious technical idea that I hope to share with the community of developers and cybersecurity specialists: Given the widespread prevalence of pornographic content online, and the difficulty of controlling it through traditional blocking or weak censorship tools, I've come up with a new system: 🔐 An "ethical operating system" (for smart devices – such as Android, iOS, and Windows) built from the ground up on the principle of: "Completely blocking any type of pornographic content, whether visual or textual, whether on websites, apps, search engines, or social networks." 💡 Key features of the idea: Its protection cannot be hacked or changed (such as the inability to install an alternative system). It can be installed on children's devices, school devices, or even the devices of adults who want to protect themselves. It doesn't rely solely on blocking a specific site, but rather on real-time content analysis. A clean app store and a clean built-in search engine. 🧱 Technically: Or as a distribution for children, schools, or conservative environments. Or even as a layer of security added to existing systems (e.g., Android). 🎯 The goal is not to impose censorship, but rather to provide a safe, ethical, and educational alternative. 🤝 I'm looking for: Interested programmers. Note that I'm only 16 years old. The goal is to find someone who will embrace this idea. Suggestions for improving the idea. Any technical or community support is possible.

    오픈 소스와 오픈 웨이트의 차이점
    흔히 IT 관련 미디어를 보면, 메타 라마가 오픈소스라고 많이 적혀져 있다. 물론 이것은 메타가 그렇게 주장하고 있지만, 정통 인공지능 개발자들 사이에서는 이러한 메타 라마가 오픈소스인가 아닌가에 대한 개념 논쟁이 많이 벌어졌다. 이게 무슨 말이냐고 하면, 100% 풀 오픈 소스냐? 아니면 가중치만 공개한 모델이냐? 에 대한 논쟁이다. 우리가 흔히 오픈소스(OpenSource)라고 하는 말은, 누구나 자유롭게 활용, 수정, 재배포할 수 있는 라이선스”라는 의미로 쓰인다. 실제로는 OSI(Open Source Initiative)가 공인한 라이선스인지, 아니면 사용 제한 조항(예: 비영리 사용만 가능 등)이 있는 “준(準)오픈소스” 형태인지를 구분해야 한다. 그렇다면, 이에 대해 한 번 알아보자! 현재 LLM 중에서 OSI가 승인한 오픈소스 라이선스는 다음과 같다. 종류: GPT-Neo 시리즈, GPT-J-6B**, GPT-NeoX-20B, Pythia 등 라이선스: 보통 Apache-2.0 또는 MIT (둘 다 OSI 승인) 특징 학습 코드와 모델 가중치를 공개 상업적 이용, 2차 재배포, 파생 모델 작성 모두 가능 라이선스: 보통 Apache-2.0 또는 MIT (둘 다 OSI 승인) 특징 “Base” 체크포인트는 완전한 오픈소스 단, “Instruct”나 “Storywriter” 버전은 상업적 이용/2차 저작 제한이 있는 별도 라이선스(MPL)를 적용하므로 주의 라이선스: CC-BY-SA-3.0 (또는 CC-BY-SA-4.0) 계열 + 모델 가중치에 대한 Databricks 에서 자체 공지 CC…  ( 4 min )
    How to Handle Surrogate Characters in UTF-8 Conversion in C?
    Converting wchar_t to UTF-8 may seem straightforward, but handling surrogate characters can complicate the process. In this article, we will delve into how wctomb works and explore alternative methods for converting surrogate characters to their UTF-8 equivalents. Understanding wctomb The wctomb function in C is designed to convert a wide character (of type wchar_t) to a multibyte character (typically in UTF-8 encoding). However, it has its limitations when it comes to surrogate pairs, which are a special way of encoding characters that are outside the Basic Multilingual Plane (BMP) in Unicode. These characters range from U+D800 to U+DFFF. When trying to convert these values using wctomb, you might encounter unexpected results. The Issue with Surrogate Characters Surrogate characters are…  ( 5 min )

    TWCT-T-D55: The Iron Throne of Current Sensing
    In the smoldering forges of Old Valyria, where currents roar like dragons and energy flows like wildfire, there sits a silent sovereign—the TWCT-T-D55. Forged in the fires of precision and crowned with 1% accuracy, this current transformer rules the Seven Realms of energy monitoring with the ruthlessness of Tywin Lannister and the cunning of Littlefinger. Let us bend the knee to the unyielding guardian of amps and volts. Chapter 1: The Forge of Dragonstone TWCT-T-D55 is no mere ironborn gadget. Cast in the Foundries of Valyrian Steel, it wields powers lost to lesser sensors: Dragonflame Precision: Measures 200A with 1% accuracy—sharper than Oathkeeper’s edge. Why it shatters the old order: Legacy CTs: Clumsy as Hodor, bumbling through phase shifts and kWh errors. Chapter 2: The War of Five Circuits The Battle of Blackwater Bay (Smart Factories): TWCTs stalk energy vampires like Arya’s List, slashing waste with Needle-like precision. “Chaos isn’t a pit. It’s a $15k savings,” they whisper. The Siege of Highgarden (Solar Farms): Guards solar arrays against hail storms and incompetence, steadfast as Brienne’s oath. “No panel left behind.” The Red Wedding (EV Chargers): Halts faulty chargers mid-zap, sparing Teslas from becoming Dothraki funeral pyres. “The North remembers… proper grounding.” The Words of House TWCT Size: Slimmer than a Braavosi blade (55mm), deadlier than a Dornish spear.

    Interviewing Software Developers: From Junior to Architect in a Single Programming Task
    Over the years, I’ve interviewed around 100 software developers at Google and roughly the same number across my own companies. One thing has become very clear: Resumes don’t work. They’re too noisy. You get flooded with titles, buzzwords, and irrelevant project summaries. So I distilled everything down to one single task. One prompt I can give to anyone — junior or architect — and instantly get a signal. The task? Write a library that calculates the sum of a vector of values. That’s it. No extra requirements. The beauty is that it looks trivial — but the depth reveals itself as the candidate explores edge cases, generalization, scalability, performance, and design. Most junior candidates start like this: int Sum(int* data, size_t num_elements) { int result = 0; for (size_t i = 0; i…  ( 5 min )

    What Is the Role Of Delegates in Objective-c in 2025?
    Objective-C has long been a mainstay in the development of applications for iOS and macOS. Despite the rise of Swift, Objective-C remains a relevant and powerful language, particularly for maintaining legacy code and integrating with newer Swift code bases. As we move into 2025, understanding core patterns like delegation continues to be vital for developers working with Objective-C. Delegation is a design pattern used in Objective-C to pass messages between objects and to provide a mechanism for customization of behavior. It allows one object to delegate tasks to another, enabling a clear separation of responsibilities and enhancing the modularity of applications. Typically, a delegate object implements methods from a protocol to respond to certain events or actions occurring in the deleg…  ( 4 min )

    Replacing Lambda Triggers with EventBridge in S3-to-Glue Workflows
    In one of our production data platforms, we used Lambda functions to trigger AWS Glue jobs every time a file landed in an S3 folder. That setup worked fine when there were only two or three data sources. But as the system expanded to support more than 10 folders, it required deploying and maintaining an equal number of nearly identical Lambda functions, each wired to specific prefixes and jobs. The architecture became increasingly brittle and harder to manage. This post outlines how that structure was replaced using EventBridge, with prefix-based filtering and direct Glue job targets. No Lambda. No maintenance overhead. Using S3 events to trigger Lambda comes with several limitations: A single Lambda function can’t be mapped to multiple S3 prefixes Each one requires separate deploymen…  ( 5 min )
    Encapsulation
    To Understand Encapsulation please do check out last post Encapsulation is like a medicine capsule: the outer shell hides the complex ingredient inside, delivering only the intended effect to your body. You don't need to know the chemical makeup to benefit from it. Encapsulation is achieved through the use of access modifiers. Python primarily uses two types of access modifier. Private: Accessible from anywhere. Public: Accessible only within the class. Similarly, in programming, encapsulation wraps data and methods in a class, exposing a simple, controlled interface while keeping the internal details private and secure. Let say I want to make "model" attribute private so that nobody can manipulate the model name. So make it private just add '__model' So, question arise if we can't access attribute but we can access function which include the private attribute. Think of like if we have attribute which you don't want get manipulated then make it private.  ( 3 min )
    How to Fix CarouselView Not Displaying Images in MAUI
    Introduction If you're developing a MAUI application and are facing issues with the CarouselView control not displaying images from an ObservableCollection, you are not alone. This article will address why images may not show up in your CarouselView, even when the same image sources work perfectly with a standard Image control. Understanding CarouselView in MAUI The CarouselView in .NET MAUI is designed to display a collection of items in a swipeable format. Each item can be customized using a DataTemplate, which lets you define how each item appears. Typically, developers use ObservableCollection to bind dynamic data to CarouselView because it notifies the view of changes. However, while you may see indicators appear correctly, images may not load as expected. Common Issues with CarouselV…  ( 4 min )
    What Is the Purpose Of Dynamic Typing in Objective-c?
    Objective-C, a primary programming language used for macOS and iOS development, has always been appreciated for its unique blend of C's efficiency and Smalltalk's dynamism. A critical feature that sets it apart from other languages is its support for **dynamic typing**. This allows for a flexible development process that enhances code modularity and adaptability. But what truly is the purpose of dynamic typing in Objective-C? ## What is Dynamic Typing? Dynamic typing refers to the ability of a programming language to determine the type of an object at runtime, rather than during compile-time. This contrasts with static typing, where the type of an object is known and enforced during compilation. In Objective-C, this means you do not have to specify the class type of an object, providing …  ( 4 min )
    Using Tailwind JIT Mode for Faster Development
    If you're still not using Tailwind CSS JIT (Just-in-Time) mode in your development workflow, you're seriously missing out on one of the biggest productivity boosts Tailwind has ever introduced. The JIT compiler doesn't just make your builds faster—it fundamentally changes the way you write utility-first CSS. Once you try it, there’s no going back. Let’s break down why it's a game-changer for modern frontend developers, and how to make the most of it. JIT mode was introduced as a way to: Compile only the CSS classes you actually use Instantly reflect changes as you code Drastically reduce build times and output file size Enable dynamic class generation Instead of scanning your entire project ahead of time, it compiles your CSS on-demand as you save files. That means faster feedbac…  ( 4 min )
    How to Select N Messages with Sum of Verbosity Less than N?
    Selecting messages with a specified sum of verbosity can be challenging in SQL, especially when the goal is to find all messages where the sum of a specific column stays below a certain threshold. In this case, we want to find messages from a table with a specified verbosity value such that the summed values of verbosity for a given set of rows remain under a specified limit, N. Understanding the Problem In our example, we have a simple table named messages, which contains two columns: id and verbosity. Given the entries: | id | verbosity | |----|-----------| | 1 | 20 | | 2 | 20 | | 3 | 20 | | 4 | 30 | | 5 | 100 | When we wish to choose rows whose sum of verbosity is less than a certain value, say N = 70, we expect to select the rows with ids 1, 2, an…  ( 4 min )

    How to Fix Rust Borrowed Data Escaping Error in Debug
    Introduction In Rust programming, a common error developers encounter is the 'borrowed data escapes outside of method' error. This typically happens when a reference does not match the expected lifetime, causing issues during compilation. In this article, we'll explore the reasons behind this error and how you can fix it to successfully print data from your NodesHeap structure while implementing the Debug trait. Understanding the Borrowed Data Error When you implemented the fmt::Debug for your NodesHeap, you're trying to generate a debug representation of your data structure using an iterator. The specific error you received states that the borrowed data escapes outside of the method. This issue arises because in your implementation of the get_all function, the return type NodesHeapIterato…  ( 5 min )
    🧠 State Management in Flutter: Choosing Between Bloc, Riverpod, and Provider
    Flutter makes building beautiful UIs fast and fun — but what happens when your app starts growing? When screens need to react to shared data? That’s when state management becomes essential. In this blog, we'll demystify state management in Flutter and help you decide between Bloc, Riverpod, and Provider — three of the most popular approaches in the Flutter ecosystem. State refers to the data your UI depends on. For example: A counter’s value Whether the user is logged in The list of items in a shopping cart State management is how we keep the UI in sync with the data — especially when multiple widgets care about the same data or when data changes over time. There are two broad types: Local state (e.g., setState inside a single widget) Global/shared state (e.g., auth status, theme, user pre…  ( 5 min )
    Why does fieldClass.getDeclaredFields() return empty in JDK 17?
    Introduction If you're using Java Development Kit (JDK) 17 and noticing that your call to fieldClass.getDeclaredFields() returns an empty array, you're not alone. Many developers have encountered this issue when attempting to retrieve field information from classes in the Java Reflection API. The Java Reflection API is essential for inspecting classes at runtime, allowing developers to gather information about fields, methods, and constructors programmatically. However, certain security restrictions in JDK 17 can lead to unexpected behavior, including the inability to reflectively access declared fields in classes like Field.class from the java.lang.reflect package. Understanding the Root Cause In JDK 17, Java introduced a more robust module system that enforces strong encapsulation by def…  ( 5 min )
    UI vs. UX: Kein alter Hut! Der Unterschied einfach erklärt (und warum du beides brauchst)

    What is fine-tuning in AI?
    Fine-tuning in Artificial Intelligence (AI) refers to the process of taking a pre-trained model and adapting it to a specific task or dataset. Pre-trained models, especially large ones like GPT (from OpenAI) or BERT (from Google), are initially trained on massive datasets using general-purpose data. These models learn a broad understanding of language, patterns, or image features. However, for specialized tasks—like medical diagnosis, legal document analysis, or customer sentiment detection—fine-tuning helps the model learn domain-specific nuances. The process involves continuing the training of the model with a smaller, task-specific dataset while adjusting the model’s weights slightly. This method allows the model to retain its general knowledge while becoming more effective in the target domain. Fine-tuning is far more efficient than training a model from scratch, saving both computational resources and time. There are different levels of fine-tuning. Some approaches adjust only the final layers of the neural network (known as feature extraction), while others allow all layers to be updated (full fine-tuning). Techniques like parameter-efficient fine-tuning (PEFT), such as LoRA (Low-Rank Adaptation), are gaining popularity, especially for large language models, because they minimize the number of parameters updated. Fine-tuning is used in a variety of real-world applications, including chatbots, image generation, fraud detection, and more. It’s especially powerful in scenarios where labeled data is limited but high-quality outputs are essential. With the growth of open-source and pre-trained foundation models, fine-tuning has become a key skill for AI practitioners. To master techniques like fine-tuning, transfer learning, and prompt engineering, enrolling in a Generative AI certification course is highly recommended.  ( 3 min )
    ExpRoot+Log: A Linear and Universal Basis for Function Approximation
    Abstract We introduce a novel numerical method, ExpRoot+Log, for function approximation based on a hybrid linear basis consisting of exponential-square-root, polynomial, and logarithmic components. This method achieves high accuracy across smooth, discontinuous, and rapidly decaying functions while remaining simple, interpretable, and computationally efficient. We show that ExpRoot+Log outperforms classical approaches such as polynomials, splines, Fourier series, and even neural networks in key scenarios, offering a new universal baseline for practical approximation. Introduction Function approximation is fundamental to numerical analysis, physics, machine learning, and signal processing. Classical bases—polynomials, splines, and trigonometric functions—have known limitations, especially near discontinuities or exponential decays. While neural networks provide expressive power, they are complex, opaque, and computationally expensive. We propose a new hybrid basis: This composition handles: All coefficients are learned linearly (e.g., via least-squares), ensuring ultra-fast performance and excellent stability. Numerical Evaluation We tested ExpRoot+Log against standard methods (polynomials, splines, Fourier) across six function types: Sine Exponential decay Step function Gaussian spike Absolute value Composite (piecewise mix) ExpRoot+Log consistently achieved 1–4 orders of magnitude lower error than polynomials or Fourier bases.

    Neuralese: The Most Spoken Language You’ll Never Speak
    Somewhere between thinking and speaking, there’s a strange place where meaning starts to solidify. It’s not quite a word yet. More like a haze of associations.

    The code review chaos we faced with GitLab (and what we tried to fix it)
    I've worked in several agile teams as both a developer and lead developer. One particular project sticks in my mind — a team of ten people, dozens of microservices, and a lot of GitLab repositories to manage. During each sprint, we were juggling features across multiple repos. At the same time, we were responsible for reviewing each other’s code. Our typical flow was: Open a merge request (MR) on GitLab Move the related Jira ticket Share the MR link in a Teams channel Move on to the next story When the workload was light, it was manageable. But in busy sprints, reviews piled up quickly. Large MRs got ignored, or rushed through. And tracking what was waiting, what was blocked, or what still needed input? A mess. We experimented with several ideas: Using GitLab labels like needs-review or blocked Adding Jira tags Rotating reviewer ownership by repo each sprint They helped — but they didn’t solve the root problem: lack of visibility and timing. Code reviews were often asynchronous and scattered. We were switching contexts constantly, jumping between repos, and forgetting which contributions needed our attention. We didn’t need more tools — we needed a better way to surface and track reviews. Something that would: Give us a unified view of MRs Let us know what’s ready to merge, what’s waiting, and what’s blocked Respect our flow, instead of interrupting it That’s when I started working on a side project, aiming to solve this specific pain point. That side project became Bellugo — a contribution tracker designed to help teams stay on top of reviews across repositories without the chaos. It’s still a work in progress, but if this resonates with your team, I’d love for you to check out the landing page and maybe join the private beta waitlist.  ( 4 min )

    Singly Linked Lists - DSA Notes 📝
    🎯 Learning Goals What are the characteristics of Singly Linked Lists? What are its time complexities? ListNode? Has a value and a next pointer next is a reference to another ListNode Order in memory may not be contiguous (unlike arrays which are) Simple while loop with a current pointer can be used: cur = ListNode1 while cur: cur = cur.next ⌚ Time complexity is O(n) , where n is the number of nodes in the linked list Now if the Linked List is circular (i.e. last node points back to first) traversing like this would cause an infinite loop. It would be helpful if we’re keeping track of the head and the tail of the linked list using pointers Advantage over array is that inserting is always O(1) even if we insert in middle. Let’s say we wanna add at the end or tail : tail.next = NewListNode tail = NewListNode # or this line 'tail = tail.next', both are correct ⌚ Time complexity is O(1) Removing any node is constant time ASSUMING we have a pointer to the previous node. Let’s say we wanna remove the second node: head.next = head.next.next # Just set the next pointer of head to the one after the deleted node Can be assumed that garbage collection will take place for the deleted node ⌚ Time complexity is O(1) For both of these operations, the caveat is if we don’t have a reference to the node at the desired position (head or tail), the time will still be O(n) Operation Big-O Reading/ Access O(n) Traversal/ Search O(n) Insertion O(1)* Deletion O(1)* *Assumes you have a reference to the node at the position (if not it is O(n) ) 206.

    Bitcoin could rally regardless of what the Federal Reserve FOMC decides this week: Here’s why
    Key Takeaways: The Fed may pause rates but inject liquidity. Crypto could rally as a recession hedge. The weak US dollar and gold rally signal a shift to scarce assets. The US Federal Reserve Open Market Committee (FOMC) interest rate decision on May 7 will be a defining moment for risk-on assets, including cryptocurrencies. While the consensus points to no change in interest rates, Bitcoin (BTC) and altcoins could see gains if the US Treasury is compelled to inject liquidity to stave off an economic recession. A more accommodative monetary policy could stimulate activity, but the Federal Reserve (Fed) is also contending with a weakening US dollar. Some analysts argue that a US interest rate cut may fail to stimulate growth as recession risks persist, potentially creating an ideal envir…

    Bitcoin price rallied 1,550% the last time the ‘BTC risk-off’ metric fell this low
    Key Takeaways: The Bitcoin Risk-Off signal dropped to 23.7, its lowest since March 2019, indicating low correction risk and a high likelihood of a bullish trend developing. Despite the recent decline in network activity, bullish macro indicators like the Macro Chain Index (MCI) suggest Bitcoin could soon rally above $100,000.

    North Korean spy slips up, reveals ties in fake job interview
    For months, Cointelegraph took part in an investigation centered around a suspected North Korean operative that uncovered a cluster of threat actors attempting to score freelancing gigs in the cryptocurrency industry. The investigation was led by Heiner Garcia, a cyber threat intelligence expert at Telefónica and a blockchain security researcher. Garcia uncovered how North Korean operatives secured freelance work online even without using a VPN. Garcia’s analysis linked the applicant to a network of GitHub accounts and fake Japanese identities believed to be associated with North Korean operations.

    Frictionless flows are Ethereum's path to economic dominance
    Opinion by: Barna Kiss, CEO of Malda An idea recently floated by some prominent thinkers in the Ethereum space to reclaim value for the mainnet is the taxing of its Layer-2s. The future of Ethereum does not depend on policy but on enabling frictionless capital movement between the L2s in question. Tariffing rollups may appear a neat way to reclaim value for the mainnet. In practice, it would fragment the ecosystem, drain liquidity, push users toward centralized platforms, and avoid decentralized finance altogether. In a permissionless system, capital flows to where it is treated best, and Ethereum's rollups mistreat it. Liquidity fragmentation is Ethereum's real threat In traditional finance, the link between fluidity and growth is well established. Lower barriers to capital inflows lead …
    What bankers, CPAs and CFOs need to know about blockchain
    Why finance veterans are still skeptical about blockchain Blockchain has been part of the finance conversation for over a decade now. Yet many professionals remain cautious.  Many seasoned professionals in finance, wealth management and economics often question blockchain’s relevance, asking, How exactly is blockchain supposed to fit into what we already do? This question reflects a few key ongoing skepticisms about blockchain within finance.

But actually applying those promises across banking, accounting and operations is still complicated. A 2021 APQC survey identified the main hurdles: a lack of industry-w…
    Dem lawmakers object to hearing, citing 'Trump’s crypto corruption'
    Representative Maxine Waters, ranking member of the House Financial Services Committee (HFSC), led Democratic lawmakers out of a joint hearing on digital assets in response to what she called “the corruption of the President of the United States” concerning cryptocurrencies. In a May 6 joint hearing of the HFSC and House Committee on Agriculture, Rep. Waters remained standing while addressing Republican leadership, saying she intended to block proceedings due to Donald Trump’s corruption, “ownership of crypto,” and oversight of government agencies. Digital asset subcommittee chair Bryan Steil, seemingly taking advantage of a loophole in committee rules, said Republican lawmakers would continue with the event as a “roundtable” rather than a hearing. HFSC Chair French Hill urged lawmakers at the hearing to create a “lasting framework” on digital assets, but did not directly address any of Rep. Waters’ and Democrats’ concerns about Trump’s involvement with the crypto industry. He claimed Waters was making the hearing a partisan issue and shutting down discussion on a digital asset regulatory framework. This is a developing story, and further information will be added as it becomes available.

This drop coincides with Bitcoin (BTC) slipping below $94,000, and the premium’s decline suggests reduced buying pressure on Coinbase, which is viewed as a proxy for both institutional and retail demand.

    Blockchains ready for institutions, lawyers hesitate: DoubleZero CEO

However, lawyers still need to catch up.  “Most blockchains nowadays, especially things like Solana, are fast enough for institutions to use them,” Federa said. “It’s really more about the institutions and the institution’s lawyers getting comfortable with crypto.” Federa added that institutional lawyers and compliance teams are still addressing regulatory concerns.

If you see these as harmless move-with-the-times digital updates of old-fashioned paper money, look again. CBDCs potentially mean financial serfdom via a monetary panopticon where the authorities closely control every transaction.  If you think this sounds paranoid, just consider the words of Augustin Carstens, head of the Bank for International Settlements — the central bank for the world’s central banks. Lamenting the authorities’ current inability to control cash transactions, he says that with a CBDC, a “central bank will have absolute control on the rules and regulations that will determine use... also we will …
    US Senate crypto bills stall amid Trump ties and ethics concerns
    Efforts to pass crypto legislation in the US Senate face mounting resistance amid growing ethical concerns around US President Donald Trump’s ties to crypto. In a May 5 letter to the US Office of Government Ethics, Senators Elizabeth Warren and Jeff Merkley said that Trump and his family stand to personally profit from an investment involving UAE state-backed firm MGX, crypto exchange Binance and World Liberty Financial (WLFI). The senators called for an urgent probe, warning the deal may violate the US Constitution’s Emoluments Clause and federal bribery statutes. At the center of the controversy is WLFI’s USD1 stablecoin, reportedly chosen for a $2 billion investment MGX plans to make into Binance. The senators said the transaction amounts to a potential backdoor for foreign influence an…
    Bitcoin Core to unilaterally remove controversial OP-Return limit
    Bitcoin Core developers have decided to remove a limit on transaction data in the next network upgrade, enabling more data to be included in a more efficient way.  “Bitcoin Core’s next release will, by default, relay and mine transactions whose OP_RETURN outputs exceed 80 bytes and allow any number of these outputs,” read the announcement on GitHub by Bitcoin developer Greg Sanders on May 5.  The long-standing limit was originally a “gentle signal that block space should be used sparingly for non-payment proof of publication data,” has outlived its utility, he added.  The proposal (PR 32359) was created by Bitcoin pioneer Peter Todd at the request of Chaincode Labs.  OP_RETURN is a special type of Bitcoin (BTC) transaction output that allows storing small amounts of data on the blockchain,…
    Celsius’ Mashinsky lashes out at ‘death-in-prison sentence’
    Alex Mashinsky, the founder and former CEO of bankrupt crypto lending platform Celsius, has blasted the government's 20-year “venom-laced” sentence request, declaring it a “death-in-prison sentence.” The US Department of Justice requested Mashinsky receive at least 20 years behind bars in the May 8 sentencing for his role in misleading Celsius users and profiting from the price manipulation of Celsius (CEL), which would make the 59-year-old 79 if he serves the whole sentence. Lawyers acting for Mashinsky argued in a May 5 reply memorandum filed in a New York district court that he should receive no more than 366 days, because the DOJ hasn't taken into account his status as a nonviolent first-time offender with a previously unblemished 30-year history in business.   “The government's venom-…

    Suspect in $190M Nomad hack to be extradited to the US: Report
    A Russian-Israeli citizen allegedly involved in the $190 million Nomad bridge hack will soon be extradited to the US after he was reportedly arrested at an Israeli airport while boarding a flight to Russia.  Alexander Gurevich will be investigated for his alleged involvement in several “computer crimes,” including laundering millions of dollars and transferring stolen property allegedly connected to the Nomad Bridge hack in 2022, The Jerusalem Post reported on May 5. Gurevich returned to Israel from an overseas trip on April 19 but was ordered to appear before the Jerusalem District Court for an extradition hearing soon after, according to the report.  On April 29, Gurevich changed his name in Israel’s Population Registry to “Alexander Block” and received a passport under that name at Isra…
    Florida takes strategic Bitcoin reserve bills off the table
    Two Florida crypto bills have been removed from the legislative process in the latest blow to American state-level strategic Bitcoin reserve ambitions.  Florida’s House Bill 487 and Senate Bill 550 have been “indefinitely postponed and withdrawn from consideration” on May 3, according to the Florida Senate.  Florida’s legislative session adjourned on May 2 without the passage of these two bills, which would have advanced legislation to establish a crypto reserve for the state. The Senate and House agreed to extend the session until June 6 to address budget plans.  Lawmakers passed about 230 bills during the session, dealing with things like prohibiting putting fluoride in the water, protecting state parks, and a school smartphone ban, but diversifying state treasury portfolios was not amon…
    Tron says DAO X hack cost victims $45K, Curve Finance also hit
    A hacker who took over the Tron DAO X account is estimated to have made around $45,000 in improperly solicited funds, according to a spokesperson from Tron.  Speaking to Cointelegraph, the Tron public relations team confirmed that on May 2, the Tron DAO account posted a contract address and sent direct messages to solicit payments in exchange for promotional advertising on the Tron account. “Our security team quickly identified the intrusion and cut off access to the hacker, but we ask the community to continue to be vigilant. We will never ask anyone for payments like this via DM or otherwise,” they said.  The team said that based on the illicit contract address the hacker posted, the amount improperly solicited appeared to be around $45,000.  Asked whether the same hacker could be respon…
    Fresh $1B in Tether mints on Tron, closing gap again with Ethereum
    The Tron network has drawn closer to regaining the lead from Ethereum in Tether circulation after another big mint by the US stablecoin issuer. On May 5, Tether minted another $1 billion Tether (USDT) on the Tron network, according to Arkham Intelligence. This brings the total USDT on Tron to $71.4 billion, according to the Tether Transparency report.  In comparison, there is currently $72.8 billion USDT circulating on the Ethereum network, so just $1.4 billion more USDT on Tron will see it become the leading network for the world’s largest stablecoin issuer, as it has been previously over the last two years.  Tron was ahead of Ethereum for USDT circulation between July 2022 and November 2024, but a large $18 billion mint on Ethereum pushed the network ahead again, according to CryptoQuant…
    New crypto bill draft seen to curb big crypto firm influence
    The new “Digital Asset Market Structure Discussion Draft” introduced by House Republicans on May 5 could work to reduce the dominance of large crypto firms and promote more participation in the broader market, according to an executive from Paradigm.  The discussion draft, led by the House agricultural and financial services committee chairs Glenn Thompson and French Hill, is an “incremental, albeit meaningful, rewrite” of the Financial Innovation and Technology for the 21st Century Act (FIT21), Paradigm’s vice president of regulatory affairs Justin Slaughter said in a May 5 X post.

    Samourai Wallet says feds hid advice that crypto mixer was in the clear
    Samourai Wallet’s lawyers allege federal prosecutors suppressed advice that the firm didn’t need a license before they charged executives at the crypto mixing service months later.  In a May 5 letter to a Manhattan federal court, lawyers for Samourai co-founders Keonne Rodriguez and William Hill said prosecutors disclosed that the US Treasury Department’s Financial Crimes Enforcement Network (FinCEN) representatives told them six months before they charged the pair “that under FinCEN’s guidance, the Samourai Wallet app would not qualify as a ‘Money Services Business’ requiring a FinCEN license.” “Shockingly, six months later, the same prosecutors criminally charged Keonne Rodriguez and William Hill with operating just such a business without a FinCEN license,” the lawyers added.
